On Wednesday, October 18th Ben Ramseth and Atma Mani teamed up to present the webinar, "Explore the Power of the ArcGIS API for Python". This webinar is part of the newly established GeoDev Webinar Series started by the Developer Outreach at Esri. These webinars were designed to keep an on-going discussion within the developer community about developer-related products, ideas, and APIs available from Esri and ways to continue assisting the developer community in leveraging their own projects with the use of our tools. In this webinar, both Ben and Atma show attendees how the ArcGIS Python API can help in scripting and automating their tasks. They take the attendees on a tour of the API and demonstrate some of the powerful capabilities such as mapping, query, analysis, portal administration, and much more.  Throughout the webinar, attendees send in their questions to get answered. At the end, Atma was able to address a number of questions, but was not able to get to all of them within the hour. We have included the remaining questions that came up during the webinar below.  Q: Are tokens consumed differently if using the API for spatial analysis or geocoding? A: No, tokens are used the same way, as when a user uses the http://arcgis.com map viewer. Q: Are you going to share the notebook used in the webinar? A: Yes…we will make the notebooks available via Github. Q: Are you using Anaconda? Do you recommend using Anaconda Python? A: Yes, we recommend using Anaconda. It comes with a lot of useful 3rd party packages. For users that have ArcGIS Pro, Anaconda ships with Pro, so no need to download and install it separately. Q: Can I use it to geocode places in Africa like Sierra Leone? A: Yes, the world geocoder with your ArcGIS Online account can be used to geocode the whole world. Q: Can scripts use aspects of both ArcPy and Python API? For example, preprocess layers in desktop using ArcPy before uploading to portal using Python API all in one script.  A: Yes, to use both ArcPy and Python API, install the API using ArcGIS Pro as explained here: https://developers.arcgis.com/python/guide/install-and-set-up/#Install-using-ArcGIS-Pro Q: Can the ArcGIS API access an ArcGIS Server that is not part of a Portal? A: Yes, we added support for stand-alone ArcGIS Servers. Q: Can we set symbol renderer with ArcGIS API for Python? A: Yes, checkout this useful resource where you can select a symbol of your choice and get the code for that symbol: esri.github.io/arcgis-python-api/tools/symbol.html Q: Can we use a "Clip" tool in Python API? A: Yes, you can clip both raster and vector layers. For instance, see this help https://developers.arcgis.com/python/guide/raster-analysis-advanced-concepts/#Clipping-to-an-area-of-interest Q: Can we use Anaconda on Python 2.7? A: No, the minimum version of Python required is 3.5. Q: I am using ArcMap10.4.1 and Python 2.7. Then can I install Anaconda? A: Yes, you can install Anaconda separately on your computer and install Python API using that Anaconda. Q: Can we use for ArcGIS server map services? A: Yes, the MapImageLayer class in arcgis.mapping module allows you use map services http://esri.github.io/arcgis-python-api/apidoc/html/arcgis.mapping.html#mapimagelayer Q: Is it possible to consolidate both (ArcPy) and ArcGIS for Python into one? A: There are no plans as of now to consolidate both these libraries into one. Q: Do we need any ArcGIS licenses to use Python? A: No, the ArcGIS API for Python is free to use. Q: Can you please provide the link to the online documentation? A: ArcGIS API for Python | ArcGIS for Developers  Q: Can you talk a bit about building/updating web applications with ArcPy? A: Jupyter project has a nice feature called 'Jupyter Dashboards' which were used in the demo. Using this, you can quickly prototype your dashboard style application all in Python. You can then decide to use a web dev language like JavaScript to build it. TO learn more about dashboards, go to http://jupyter-dashboards-layout.readthedocs.io/en/latest/ Q: Can you use python to create groups/subgroups to publish layers in ArcGIS portal? A: Yes, checkout https://developers.arcgis.com/python/sample-notebooks/publishing-sd-shapefiles-and-csv/ and the rest of the publisher samples Q: Can you use the API to automate the downloading of data from AGOL? A: Yes you can. Check out this lab: https://developers.arcgis.com/labs/data/python/download-data/ Q: Can you use the Python API to update description sections in Story Maps? For instance, automate a nightly process to pull a description field text from a database row and overwrite an existing description section in a Story Map. A: No, this is currently beyond the scope of the API. However, you can read the story map data using Item.get_data() method and make updates. Then call Item.update() method to push the changes. Q: Can you use your custom created basemaps with the API? A: We are adding support for this feature. Q: Does analysis in Jupyter Notebook use credits? A: Yes, it uses the same amount of credits as when doing it using ArcGIS Online Q: Any Special instructions for installing the module with Conda behind a corporate proxy?  Is there a .tar file available instead? A: Yes, you can perform an offline install. Instructions and helper scripts are here: https://developers.arcgis.com/python/guide/install-and-set-up/#Offline-install Q: Hi all. Is possible to develop a spatial regression analysis (OLS, logistic regression) with this ArcGIS API for Python inside Jupyter?  A: Yes, Python API can be used to read data from feature layer. Then using third party libraries like Scikit-Learn Ordinary Least Square regression or any other regression can be preformed. The results can then be published back to the GIS using the Python API. Q: So I assume the dependent variable and independente variable can be set up in Sklearn through the columns of the attribute table of my feature layer. Right?I  have JSON files from a HTTP rest of a mobile app about destinations. Is possible to convert this JSON to GeoJSON with ArcGIS API for Python? And return this new GeoJSON to my HTTP rest and use this in ant webmapping with Web Appbuilder? A: That is correct. We are adding support for GeoJSON, so not possible now. Q: Can we define new widgets for Web Appbuilder with this API? A: No, that is beyond the scope of the API Q: What's the function we can use to copy Annotation feature class fastest with a where clause to a SDE database? A: We would recommend looking into using ArcPy to accomplish this. Q: If I have anaconda for Python 2.7, I have to install Anaconda for Python 3.6 for the ArcGIS API? A: That is correct. You will have to install Python 3.x to work with the API. Q:  I would like to bulk process a large number of landsat and sentinel images on the API without having to download them individually. Is there a way to invoke the respective Landsat and Sentinel libraries using the API? Also, if you have time, could you show a possible example of a "for loop" to process a certain number of images, perhaps looping a cropping process? A: The best way is to create a mosaic dataset using the images and publish them as image services. Then you can define masks using raster functions which are equivalent to clipping. We will plan to write a sample explaining the workflow in future.   Q: How do you import ArcPy into your Jupyter Notebook? A: You must install the Python API as explained here https://developers.arcgis.com/python/guide/install-and-set-up/#Install-using-ArcGIS-Pro. Then start the 'Python command prompt' app and type 'Jupyter Notebook'. Now you can import both ArcPy and the Python API. Q: How is python API different from Javascript API ? A: They are similar in that they both work with web GIS using the ArcGIS REST API. The difference comes in the purpose you would use each for. JS for building web app, Python for automating and managing your web GIS - users, groups, services, items, maps etc. And Python API allows you to make use of the rich data analysis ecosystem possible with Python. Q: Can Python work offline and can it work in Demo? A: Yes, it can. You would need an ArcGIS Enterprise in your disconnected network for the API to connect to and work offline. Q: I have ArcMap on my computer. How do I get the ArcGIS API in ArcMap? A: You need ArcGIS Pro to get Python API. Or you can install anaconda and install Python API. Instructiosn here: https://developers.arcgis.com/python/guide/install-and-set-up/. Q: Do I need ArcGIS Pro installed to use the ArcGIS API for Python? A: No, its optional. Q: If you export code to .py and run, will maps open similarly to the Jupyter environment? A: No, you need the Jupyter Notebook IDE to visualize the map widget. Q: In the demos, everything is typed in the Jupyter Notebook by the user. But how do you script this in a file and how do you schedule this script (like with a task scheduler)? A: You can use the API from a Python script instead of a Jupyter Notebook. But if you already have a notebook, you can download the notebook as a Python file from the File menu. Q: Is it possible to combine both ArcGIS Pro ArcPy and Python API into one Jupyter Notebook to make use of both ArcGIS Online data connection and ArcGIS Pro analysis capabilities? A: Yes you can. You need to install the API using ArcGIS Pro as explained here: https://developers.arcgis.com/python/guide/install-and-set-up/#Install-using-ArcGIS-Pro Then you can import both ArcPy and Python API into your scripts. Q: Not very related to ArcGIS API: In ArcMap i was able to create AddIn, in future will be possible create Python AddIn in ArcGIS Pro? A: Yes, you can make add-ins with Python; however, they are made with ArcPy, NOT the ArcGIS API for Python. Q: On your online Jupyter Notebook site do you have a sample of using an SDE source to update ArcGIS online data? A: No, we don’t have one. But, we will consider this for future. Q: So at this point (locating address) you're creating a new point layer and filling in attribute fields just by geocoding that address? A: Yes, thats correct. Q: What about SAML say with Okta?  A: Users with SAML are recommended to connect using Arcgis Pro. Help link is here: https://developers.arcgis.com/python/guide/working-with-different-authentication-schemes/#Connecting-through-ArcGIS-Pro Q: What is the module for accessing and adminstering ArcGIS Server directly? A: It is the 'server' module. Help doc here: http://esri.github.io/arcgis-python-api/apidoc/html/arcgis.gis.server.html# Q: When I do a process in ArcGIS, can I see the process the Python script? For example, let's say I do some step to get the NDVI (Normalized Difference Vegetation Index). If I do a process for getting it, can I see this process that I did in Python? A: If you used Python API, then yes, the Jupyter Notebook keeps a record of it Q: When you are using the "tools" like buffer or hotspot are you consuming credits? A: Yes you are consuming credits. Q: Where are the iPython Notebooks you mentioned in your introduction?  A: GitHub - Esri/arcgis-python-api: Documentation and samples for ArcGIS Python API  Q: You say the Python API can be installed using ArcGIS Pro, does it install this jupyter program too? A: Yes it does install Jupyter Notebook as well. Q: You showed shapefiles to publish, what's the best way to publish geodatabase content using the API to enterprise or online? A: You can zip your file geodatabase and publish that as a feature layer. Q: Can the ArcGIS API for Python easily do with geo-analysis/process, similar to the toolbox in ArcGIS Desktop? I see arcgis.geoprocessing module in the online Reference page. But I do not see the sample code and wonder if this module can connect with tools in ArcGIS Toolbox. The reason to ask the question is that we have some complicated geo-processes at the desktop level. I wonder if the complicated geoprocess can be moved to AGOL. A: The doc here explains how to use geoprocessing tools form Python API and contains sample code https://developers.arcgis.com/python/guide/an-introduction-to-geoprocessing/ Q: Can the ArcGIS API for Python connect with SQL Server? My organization only uses SQL Server. A: Python API cannot direclty connect to your SQL server. However you can use Pandas library to connect to it, read data then use Python API to publish that layer to your GIS and make it available for rest of the analysis or processing. If you do not see a question you have listed above, leave one in the comment section below, and we'll check it out and get you your answer!

Now, in our fifth annual Developer Summit Europe conference, as much as we have learned over the years, we have also grown and are better than ever. Here are some highlights from the event and all of the enriching sessions, activities, and networking opportunities that took place: Pre-Summit Hands-On Training While short tech sessions during a conference are a great way to spin up on the latest tools and capabilities within an API, sometimes nothing beats spending a day getting some hands-on training, to put your hands (and your code) directly onto an API, to build up skills that you can put to productive use right away in your work, apps, and projects and given that JavaScript is the most popular app development API among our user community, and Python is more and more the 'language of the ArcGIS platform', we figured those two would be most popular amongst those who chose to attend DevSummit.  ArcGIS Python API - Ben Ramseth introduced the ArcGIS Python API, which allows ArcGIS users to automate their workflows and perform repetitive tasks by writing Python scripts. With about a dozen attendees, Ben taught about automating the administration and management of an ArcGIS Enterprise and ArcGIS Online Organization, cloning contents of one portal to another, analyzing GIS datasets, creating illustrative reports using Python notebooks, and creating new content or publishing the analysis results as web layers and web maps. ArcGIS API for JavaScript - Andy Gup leads attendees along the  journey of creating web apps featuring ArcGIS content and capabilities. ArcGIS API for JavaScript 4.x streamlines app development and capabilities to incorporate 2D and 3D content. Andy takes this workshop to introduce the API classes, components, and functionality to help users create web applications. Plenary The following format for the plenary this year was quite different from years passed. Instead of the usual ArcGIS theme, we chose to focus on more of the APIs and their features: Introduction to the DevSummit ArcGIS for Developers ArcGIS API for JavaScript ArcGIS Runtime SDKs The ArcGIS Developer Experience ArcGIS Pro .NET SDK ArcGIS API for Python Many of the attendees appreciated this format and felt that it really answered a lot of the questions they had about our upcoming features and available tools. We also enjoyed presenting in this format and will consider maintaining it in the future. Technical Sessions Over 45 unique technical sessions were offered at DevSummit. Some of the presentations included, but were not limited to, the following:  JavaScript ArcGIS API for JavaScript: Building Mobile Web Apps was presented by Andy Gup. This session helped users to learn about important design and implementation considerations for building mobile apps for JavaScript through the use of a Mobile First approach. App Design and CSS Styling with the ArcGIS API 4.x for JavaScript was presented by Allan Laframboise. This session covered how to work with CSS for the new ArcGIS API 4.x for JavaScript. It included how to perform the manual overrides, access to the SASS libraries, and how to re-build the CSS libraries to create custom versions. ArcGIS API for JavaScript: Tips and Tricks for Developing and Debugging was presented by Mark Jagt and Maarten van Hulten. This session helped users to learn quickly and easily how to find and fix problems in their web mapping applications. It helped to guide users how to set up their dev environment to write cleaner code. They showed users some debugging tools to debug, style, and optimize their apps.  Runtime  ArcGIS Runtime SDKs: An Introduction to the API and Architecture was presented by Euan Cameron and David Cardella. This session presented an introduction to the Runtime SDKs, the advantages of using them, and an overview of the API.  ArcGIS Runtime SDKs: Building 3D Applications was presented by Mark Baird and Luke Smallwood. This session provided details and inspirations for developers as they think of using 3D as they design and build their Runtime apps. ArcGIS Runtime SDKs for Qt, Android, and Java: Building Apps sessions were presented so users developing on Windows, Linux, Desktop, and smartphone/tablet applications could use Runtime to easily build interactive mapping applications. Python Administering ArcGIS Enterprise and ArcGIS Online with Python was presented by Rohit Singh and Ben Ramseth. This session taught Web GIS administrators how to use the ArcGIS Python API to automate some of their most repetitive tasks and use scripts instead of the UI and clicking through.   Geospatial Data Science and Analysis using ArcGIS API for Python was presented by Rohit Singh and Matthias Schenker. This session covered how analysts and data scientists can use the ArcGIS platform in combination with data science libraries from Python for mapping, visualization, and geospatial data analysis.  Arcade ArcGIS API for JavaScript: Using Arcade with Your Apps was presented by Rene Rubalcava. This session provided an overview for users on how to navigate the Arcade documentation while highlighting some key functions available in Arcade. Rene demonstrated how the live Arcade editor in ArcGIS Online could be a powerful tool in helping attendees write, edit, and execute custom expressions.     Sponsor With sincere thanks and gratitude, we would like to take a moment to share how very important con terra is to us as an organization. Without their support, our event would not be the same. Their participation at our Esri DevSummit events has been invaluable, and we are overwhelmed with appreciation for all that they do in this #geo world. Many thanks to you, con terra! Tech Talk In between tech sessions and breaks, we had our Tech Talk areas: Desktop, Native, Web, and ArcGIS Online/Enterprise. These areas were housed with Esri staff so that at any time, a user could walk up and ask a question they may have related to those areas. Most users found this quite useful when they had remaining questions that they wanted to have answered that may have been a bit more specific about their use of our platform. Developer User Community Events SpeedGeeking This event is a great way to break the ice with some of our attendees by inviting them to listen to a new technology or feature of our technology that an Esri presenter shares within five minutes. Borrowing the concept of SpeedDating, we ask users to select one of our twelve stations to start, and we start the clock for our presenter to talk for five minutes. Within the hour, all of our attendees are able to learn about each new idea/concept/feature in a fast and unique way. Here were our speakers and what they covered: SpeedGeeker Title Andy Gup Using Angular with the ArcGIS API for JavaScript Ben Ramseth Using the ArcGIS API for Python Rene Rubalcava WebGL or Bust! Simon Haegler CityEngine and the Unreal Game Engine Niklas Koehn Extension of Standard Web AppBuilder Widgets by Inheritance via TypeScript Antti Kajanus Taking a Webmap Offline with ArcGIS Runtime Daniel Cronin World View - Building a Chrome Extension with Esri Leaflet Matt Jones Mapstyler - Styling Vector Tiles using Photos Javier Gutierrez 3D with the ArcGIS API for JavaScript Matthias Schenker Augmented Reality User Presentations Users were given the opportunity to present their own development projects and ways they've leveraged the ArcGIS platform.  Sven Aanesen from Geodata in Norway presented his talk, "Success with Custom Native Apps". In this talk, Sven discusses how Geodata is helping the Norwegian Environment Agency with mapping nature types in a classification system. They have developed an advanced and customized iPad app to do so. They have a unique user interface with focus on quick user input, ease of use, and advanced geometry sketching with a complex set of rules. The app has proven to become a much appreciated tools for the users. The collection of very detailed data is performed outdoors every summer and is using ArcGIS SDK for offline support. This user presentation was a great example of how our users are able to leverage the usage of ArcGIS to expand their product to their customers and other agencies. Lightning Talks  We had a few great lightning talks this year that covered routing, street level imagery, and the use of OpenStreetMap (OSM) on ArcGIS Online. Christopher Beddow from Mapillary covered using their API and integrations in general with the Esri JavaScript API, Web AppBuilder, ArcGIS Online, and also what they've been able to gain from their use of ArcGIS Pro. Simon Geigenberger presented his five minute lightning talk on the Python script he wrote that can be used to convert data from OpenStreetMap into Feature Services that can be hosted on ArcGIS Online. In his talk, he describes the main steps from OpenStreetMap to ArcGIS Online: Read and validate configuration data Get the data from OpenStreetMap Store the data in the pandas data frame Publish the data on ArcGIS Online Finally, he showed a feature service that is published using the script. Jans Wilkening presented a web-based 3D campus routing developed at the University of Applied Sciences in Würzburg that solves the problem of finding rooms throughout buildings on university campuses. The solution presented was based on ArcGIS Desktop, the JavaScript API, and a Network Service hosted on the ArcGIS Server.  The Party We returned to Hofbräu in Berlin for our Wednesday night party. With a nice selection of meat, potato soup, pretzel pieces, and beer, our attendees and staff were able to enjoy each other's company and introduce one another and what we do in a relaxed setting. It was a great time had by all, and we were able to make new friends and lasting work relationships. Closing While goodbyes are always difficult, the closing session at DevSummit is the greatest way to gather feedback and address questions that come up throughout the conference. We also get to share some pretty fun stats on how much food was consumed, how many attendees we had with us, and where the audience feels we should focus our attention for future developer conferences. We had a great time spending the week with the developer community throughout Europe in Berlin, and we look forward to what is in the plans for next year's DevSummit Europe! ... View more

We had so many great questions during our "Discovering the ArcGIS API 4.x for JavaScript" webinar, that we decided to share them all with you! We hope by answering some of these questions, we will open up a dialogue with you from the comments you leave below. Feel free to follow up and keep checking this page's comments section for more contribution. Q: Will Arcade expressions work inside TypeScript? If so how? A: Arcade is it's own expression language; it's not JavaScript or TypeScript. Q: I have been looking for a way to use the directions widget in the 4x. But I have not found the documentaion yet except in the 3x. I will be happy if the directions widget could be included in the 4x or could you show me how.  A: Directions widget is planned for 4x, but there is no timeline on when it will be ready. Q: If I'm using ArcGIS Online instead, could I do it? I mean, instantiating a web map created in ArcGIS Online and controlling it in JavaScript, because I couldn't find the portal item ID if I created it in the ArcGIS Online or make it public?  A: This is custom app development using ArcGIS Online services. Q: What software do we need for creating web GIS apps? A: An editor like Atom, Visual Studio Code. And just a free developer subscription for creating layer items and web maps. Q: Can I create one app that works on desktops and phones? A: You can create a web app that would be performant in both. You can read about Progressive Web Apps here (https://developers.google.com/web/progressive-web-apps/). You may also want to look at Cordova (http://cordova.apache.org/). Q: If I have a 2D map with multiple layers, say I have two different layers but I want them to be both displayed on the same map, but only certain parts of each legend in each layer - can this be done? A: You can disable layers from showing in the legend if desired (https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-FeatureLayer.html#legendEnabled). Q: What application are you using to write code and view those maps? A: We are using Reveal and CodePen. Q: I see a lot of good support for 2D Maps in JS API 4.4, so why we should use 3.21 to build 2D maps and 4.4 to build 3D maps? in other words, what does 3.21 provide that 4.4 does not provide? A: 4.x is our next generation JavaScript API that implements many of the latest JavaScript patterns and practices. 3.x uses patterns and practices that are now over seven years old. You can refer to the functionality matrix (https://developers.arcgis.com/javascript/latest/guide/functionality-matrix/index.html) to see if you need 3x capabilities or could get by with 4x until feature parity is complete. Q: Can you code the popup to be moved on the map? A: This is not a feature built into the popup, but you might be able to customize this yourself. We have no samples of this. Q: What if you don't have longitude and latitude, but you have X,Y coordinate? A: X,Y works with defined spatial reference when you create a layer. Q: Is there a book available to get started with tutorials? This is overwhelming. A: We recommend reading the topics under the Guide section of the API docs. You can also take a look at our DevLabs which are 10 - 15 minute step-by-step learning aid. Here are the links: https://developers.arcgis.com/labs/ and https://developers.arcgis.com/javascript/latest/guide/discover/index.html. If you are looking for getting started with JavaScript, then we recommend doing internet searchs until you find tutorials that match your expectations. There are so many we can't really determine which ones are best for each person. Q: Jumping the gun, I know, but I've been working with SceneViews, elevationInfo, and 3D renders a lot lately. Will the API eventually have support for either setting/modifying z values via Arcade expressions or/and setting elevationInfo.offset via Arcade expressions? We have a lot of "3D" data that is not 3D and use cases where we may not want to use actual elevations, for instance, exaggerating vertical distance between building floors to show all space owned by a department within a building.  A: The 4.5 release and documentation will have a property on elevationInfo called featureExpressionInfo that should meet your needs. Q: Will we ever be able to set elevationInfo.offset or set/modify Z values via Arcade expresssions? A: The 4.5 release and documentation will have a property on elevationInfo called featureExpressionInfo that should meet your needs. Q: Any documentation on "Best Practices when working with JS API for ArcGIS"? A: Yes, under the https://developer.arcgis.com/javascript home page. Q: Can we use 3D sketchup models directly into Portal/AGOL using JS API to view the models? A: You would need to export out of CityEngine or try to convert to multipatch in Pro and publish a scenelayer. This doc may help (http://pro.arcgis.com/en/pro-app/help/projects/styles.htm). Q: WIll the draw option work in 3D view as well? A: Not in the 4.5 release, but is on the roadmap for a future release. Q: Do you require anything other than the out-of-the-box portal to load an Excel sheet (e.g. a geoprocessing server / extension)? A: No, you just want to save the excel file as a CSV and upload it. Q: Is there any rest layers grouping option in ArcGIS Online or ArcGIS JavaScript APIs? A: You may be looking for the GroupLayer (https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-GroupLayer.html), but you can't group layers in Online at the moment. Q: Is there still no editing capabilities in JS API 4x? A: A widget with editing capabilities should be coming early- to mid-2018. However, in the meantime the 4.x API can programmatically add, update or delete features using FeatureLayer.applyEdits(). Q: Do vector tile layers sit on top of basemap layers or are they considred a basemap layer? A: Vector can be basemap Q: Do Arcade renderers show up in an updated legend? A: Arcade is not a renderer; it's used within an existing renderer to extend its capabilities. Q: Incompatible spatial reference? Does that mean non-web mercator? A: The map can be in any projection, but we can only reproject layers from mercator <-> web-mercator.  Q: Can it be used to build mobile web apps with HTML5 Web Storage support (i.e., offline)? A: It can, but a mobile offline experience is tricky with maps. A better option is our native Runtime SDKs https://developers.arcgis.com/arcgis-runtime/. Q: Is mapview compatible with other basemaps from Mapbox, CartoDB, etc.? A: If you can provide the schema of the tiles, you can use WebTileLayer (https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-WebTileLayer.html), but we can't load the Mapbox vector tile. Q: Can you please recommend an Esri Virtual Course for a true beginner. That is, for the first time a student will be exposed to APIs and JavaScript? A: We recommend finding an online JavaScript course that fits your needs, W3 schools is a great introduction to the basics: https://www.w3schools.com/js/default.asp.  Q: What are the main differences between using the ArcGIS API and using ESRI's open source esri-leaflet? A: The ArcGIS API for JavaScript fully supports the ArcGIS Platform. Esri-leaflet is a good soultion in some cases, but does not support all the features of the platform. Q: Can we create WebMap Applications using AGS JS API with Angular's latest version? If yes, then how, and can you help me to find resources and help for this? A: We have various resources on github (https://github.com/Esri/jsapi-resources/tree/master/frameworks/angular). Q: Streaming Layer, data has to come from geoevents server or we can have a custom service? A: You can use your own web socket server as long as it emits Esri JSON format. Q: I'm a beginner level in GIS; please give your valuable suggestions. A: Please checkout our online free and other paid training opportunities. If you got to the following link and type the word JavaScript into the catalog search you'll find many options: https://www.esri.com/training/catalog/search/. Q: What is this pricing of this API for commercial apps? A: Please see this pricing as a starting point: https://developers.arcgis.com/pricing/. Q: Do you have to use TypeScript when creating your own widgets? A: If you want to use the widget framework with the API, yes. But you can write widgets in any framework and use the ViewModels if you like. We hope this list of Q&A helps! Please leave comments below for any other questions you may have. There were also some questions asked during the webinar itself. If you missed it, here is the recording:  Discovering the ArcGIS API 4.x for JavaScript - YouTube  ... View more

The Developer Outreach Team is proud to announce the solution to your DevSummit withdrawals! We listened and are excited to keep the greatest developer event going throughout the year via our GeoDev Webinar series.  This is no ordinary developer webinar series; it’s a webinar series produced by developers for developers. Looking to build web, mobile, and desktop apps for any device? Learn as Esri Developer Outreach advocates demonstrate how the ArcGIS APIs, SDKs, and analytic capabilities can help you to do this! Join us to learn about the latest geospatial tools on the ArcGIS platform. Our first webinar to kick off the series is "Discovering the ArcGIS JavaScript 4.x API", presented by Andy Gup and Rene Rubalcava. We understand how those of you who have been using 3.x and prior are interested in checking out how 4.x has improved and simplified the API. Its ability to work with map and layer web resources stored as items in the ArcGIS geoinformation model, and its support for building engaging and elegant user experiences is the draw for learning more. There are new capabilities that developers can use to make #webmapping #apps better than before. There is now native support for #vectortiles, and #widgets are extensible and more useful with #UI frameworks other than Dojo. There is also the capability to create local builds using our #Bower package on #GitHub. When it comes to apps that work with and edit features, improve the performance of your app using the #geometry #engine to do this work all on the client side, right in the browser.  Register for a webinar today! ...

Tomorrow the Developer Outreach Team is hosting a PubNub webinar: "Mapping and Tracking That Your Users Crave". Apps today are driven by realtime, interactive maps. What better way than to show you how to create these maps and use your data to give your users the experience they are craving in navigating? Presenters Andy Gup's Blog‌ and Geeknixta's Blog‌ share not only the ins-and-outs of realtime mapping, but they also show how to implement geo-tracking, route planning, and more using Esri BLOCKS.  Interested in attending the webinar?

Last week, Esri's NYC office teamed up with The Mount Sinai Adolescent Health Center’s MAPSCorps team, which is comprised of college student leaders (the Field Coordinators) who manage teams of high school students (the Youth Mappers) who then serve as mobile data collectors to itemize and validate the locations, status, and attributes of various resources, in selected neighborhoods across NYC. The student teams then analyze the data collected against various health problems identified for those neighborhoods and communities as part of their summer symposium presentations. At the present moment, the MAPSCorps program are using ArcGIS to help them manage data collected in the field and map it, analyzing resource availability for these specific health issues and services. ArcGIS Story Maps will be used to present their observations, findings, and stories through flexible, interactive, and functional web application. This is where we came into the picture... On July 31st, staff from Esri’s NYC office conducted a workshop for the college student leaders. We needed to cover a lot of ground fast, and get them productive as soon as possible, so the workshop followed the Data > Design > Develop pattern. Hands-on examples were used to have the students practice with techniques for working with data: for searching, finding, converting, modifying, creating, editing, and verifying it all. The better the data, the better the solution. Luckily the City of New York is one of the more forward-moving cities in the U.S. when it comes to its support of transparent government and citizen engagement supported by open data. It was great to see how inspired the students were to apply our tools and make a difference. We look forward to following up with them in the month of August to see where their work on Story Maps takes them.  To be continued... ... View more

Tomorrow the #Esri #GeoDev team will be hosting our free four-hour hands-on HackerLab at the Esri R&D Center in Portland, ME. Later, we will be joining Jeff Jackson and his team in presenting some lightning talks in the evening at Oxbow Brewing Company. The Developer Outreach Team tries to reconnect with all of the R&D Centers throughout the year, and this our second HackerLab event held in the R&D office. We look forward to reconnecting with the developers within the area to see how we can introduce the ArcGIS platform into their work.  Later, we will convene for a meetup at Oxbow, our go-to brewery for hosting the perfect event. We are able to utilize their large gathering space for presenting and lightning talks. We have the following lineup of speakers for tomorrow: • Randall Berry, “Constructing Opensource Visualizations For Expected Future Emergencies (COVFEFE)?” • Phillip Ulbrich, "FEMA GIS - 311 Data Project: Damage Collection Info from a Disaster" • Tim Walsh, "GIS and Asset Management at Portland Water District" If you are a developer in the Portland, ME area and are interested in attending either of these free events, please RSVP to them via Meetup.com: HackerLab: Esri HackerLab - Portland, ME - GeoDev Meetup Group - Northeast (New York, NY) - Meetup  Meetup: GeoDev Meetup - Portland, ME - GeoDev Meetup Group - Northeast (New York, NY) - Meetup  We look forward to seeing you there!

What a night for a GeoDev Meetup in San Diego, CA at the Esri User Conference! The weather was gorgeous, the setting was breathtaking, and the company was, well, it was with our developer community, so needless to say, no short of amazing. In our 6th year of hosting a GeoDev Meetup at UC, we've learned a number of things: 1) always have enough food and beverages; 2) allow for enough time for users to get to the meetup from the San Diego Convention Center; and 3) be prepared to be amazed by some of the most talented individuals to ever grace your presence. Yep, our users are that good. We had over 200 developers from all over the world attending; they came from around the U.S., Japan, Berlin, and South America. We had such talent with backgrounds in coding, analytics, spatial development, and GIS management. We even had numerous individuals returning back to Esri to drop by and say hello to current Esri developers. It was an evening to remember.  This social was an opportunity for our developer community to gather together and discuss what they have moving and shaking in their world. It is the one time where the developer community can really delve into conversations as deep as they can possibly go and exchange sources that can move developers into a new direction or at least open their eyes to the possibilities that await them as they continue building and designing off of the ArcGIS platform. To encourage our developers to grow in the use of ArcGIS, we held a giveaway for two registration seats to Developer Summit. Our two winners have both been very engaged in our GeoDev Meetups around the nation and having them win a complimentary registration means that much to both them and to us. Overall, the event was a success and we look forward to next year's. We are always looking to improve and would welcome any suggestions or ideas that might help us to do just that! ... View more

At UC last night we hosted the Lightning Talks, and it was even better than ever! Even our new location didn’t thwart the interest that came into Ballroom 20A on Monday evening. With 19 presentations ranging from 3D to open data, users came from Brazil, New Zealand, Mexico, and even Africa to share some of the work they’ve been doing with Esri’s software in five minutes or less. With over 300 people in attendance, the speakers got a great sense of community and comradery  as they engaged and laughed along with the fun ideas and imagery that the presenters creatively played within their 300 seconds of glory.   We even had a couple of our winners from the USC Viterbi Fellows Grand Challenge Hackathon that took place this year February 3 – 5 th . Trisha Palit and Maria Camasmie presented their application that won at the hackathon challenge: Maji. It was great to hear their development and the work that they’ve done with it as it came to fruition. The event was sheer success! We only had to pull maybe two people off of the stage, as their presentation time hit five minutes. We show no mercy, but the presenters understand. They just get so excited to be up there and have so much to say! But that is the beauty of the event – it’s only five minutes! The briefness of the event allows for the community to have their interest piqued, but not so much so as to inundate anyone with information they may or may not find useful. Just a taste is enough to get others involved and interested enough to obtain presenter information for more details later.   See the full list of presenters and their lightning talks below. If you are interested in viewing some of these presentations or getting in touch with the presenters, do not hesitate to contact us for more information.   If you are interested in participating in this event next year, please let us know! We would love to host this event again and would love to hear about your interest.   Presenter Presentation Molly Burnhans ArcGIS for Budgeting, Project Management, and Strategic Planning Matthew McLamb GreenCity GIS Trisha Palit and Maria Camasmie Maji Gareth Gibson Augmented Reality is the New Reality Leena Gautam ArcGIS GeoPDF Streamlines Field Operations Vic Baker FTP Data Mining: Hadoop + Esri Norman Mucha ARCMAP Helps an Art Museum Boost Membership and Attendance!
