Let me know any questions or comments below and Julia Shi or myself can assist. 

I hope you have had a chance to explore the March ArcGIS Online Update. A feature that was not as heavily promoted but is still noteworthy is the ability to create a hosted table directly from My Content. This new feature is useful for whenever you want to create data in ArcGIS Online that doesn't have a spatial component. 

 

Create the non-spatial hosted table by browsing to Content > Create > Feature Layer > From Template > Build a Layer > Table. 

 

 

Once the table is created you can define the schema in the Data tab:

 

 

Finally, add data to the table using Update Data > Append Data to Layer. 

 

 

How do hosted tables fit in with your existing workflows? I hope you found this post helpful; let me know any questions or comments below!

 

Most of us have not been through something like COVID-19 before. Many authorities and agencies have turned to ArcGIS Online applications to disseminate crucial COVID-19 related information and gain insight for how to respond. You might have come across the Johns Hopkins dashboard, or the web experience created by World Health Organization.

 

ArcGIS Online can be leveraged as a powerful tool for your organization and community in this difficult situation as well, and the picks for this week are intended to provide a firm foundation for getting started. They provide some newly updated best practices for preparing highly scalable ArcGIS Online web applications, comprehensive resources and crucial steps for mapping and understanding COVID-19, a brand new solution template for collecting and sharing information with the public related to the outbreak, and a living document that has collected and categorized COVID-19 dashboard examples, educational resources, questions, and solutions on GeoNet. 

 

Essential Configurations for Highly Scalable ArcGIS Online Web Applications

 

ArcGIS Online Product Manager Kelly Gerrow published this excellent, interactive blog post on the essential best practices for preparing layers and apps for very high demand. As Kelly writes, ArcGIS Online is built on scalable architecture that has supported millions of views per hour on the Johns Hopkins dashboard. The blog features a checklist where you can literally toggle off each setting for your layers and apps as they are configured, ensuring that you tap into the technology that has facilitated this massive-scale information sharing. As the title suggests, it is truly an essential read.

The Tools to Get Started

 

Esri has been working to make resources available for mapping, analyzing, and understanding the spread of COVID-19, as well as gathering information from and sharing information with your community regarding the pandemic. On Esri's COVID-19 Hub Site, you can learn where to begin, access authoritative data and get updates from national agencies. If you want to create your own website to share information and resources with your community, this blog post is an ultra-comprehensive step-by-step guide for accomplishing this using ArcGIS Hub (as many government agencies have already done). And just yesterday, the ArcGIS Solutions team released Coronavirus Response | ArcGIS Solutions for Local Government - this features 10 applications specifically designed for use by the public and public health staff to "to understand the impact of the coronavirus (COVID-19) and share authoritative information about the pandemic with your community." 

 

Join the Conversation on GeoNet

 

Naturally, some of the conversation about the GIS response to COVID-19 has occurred on GeoNet. Leslie Fountain has curated a compelling, living document with links to data sources, dashboard examples, educational resources, and a collaborative spacewhere unanswered COVID-19 questions are highlighted. Taking a look at this space and seeing if you have experience with one of the questions may be a great way to help out a community from afar. 

 

I hope that the picks provided some guidance on the ways that GIS solutions can assist during these challenging days. Let me know in the comments below if they were helpful or if you have any additional questions. Keep an eye out for This Week's Picks - ArcGIS Enterprise & This Week's Picks - ArcGIS Pro. Thanks for reading - my sincere best wishes to you and yours. See you on Tuesday, 3/31.

When an ArcGIS Online update is slated for the near future, I tend to reflect on functionality that has been recently added to the platform. With an update planned for later in March (see this post to participate in the Beta), I realized that there have been a couple of key updates to vector tile layers within the last year. In case you are new to ArcGIS Online within the last couple of months or weren't using vector tiles when the updates went out, the picks for this week showcase some of my go-to vector tile layer resources. I hope you enjoy!

 

Vector Tile Layer Style Editor (Native in Map Viewer)

 

This feature was released in June 2019. Without leaving the Map Viewer, create and save your very own custom style. Zara Matheson's excellent blog will walk you through exactly how: Edit Vector Tiles in Style from Map Viewer 

 

Additional Resources:

 

 

Replace Vector Tile Layers

 

Replacing a vector tile layer with updated data, from the Graphic User Interface (GUI), with minimal downtime, came to ArcGIS Online in October 2019. Garima Tiwari's blog describes in a succinct fashion how to accomplish this: Update hosted vector tile layer content using Replace Layer 

 

Additional Resources:

 

 

Understand the Root Tile

 

When creating vector tile packages in local tiling schemes, it is important to understand the root tile. This Esri Support knowledge base article, written by senior analyst Adam Eversole, sums it up nicely then goes deeper: "If a tile cache were a pyramid, the root tile would be its peak. It is the tile that represents the largest area of the map and the lowest level of detail." This is required reading for those wanting to publish hosted vector tile layers in a local projection. 

 

Additional Resources:

 

 

I hope the above picks provided some guidance and inspiration for working with vector tile layers! Let me know in the comments below if there are any questions, comments, or if there is any content you want to see in the future. Don't forget to keep an eye out for installments of This Week's Picks - ArcGIS Enterprise & This Week's Picks - ArcGIS Pro, coming later this week. Thanks for reading and see you again on 3/17. 

 

Cheers,

As an ArcGIS Online administrator, you have control over just about every aspect of your ArcGIS Online organization. From inviting members, assigning licenses and managing groups to configuring credits, security settings and utility services, you the ArcGIS Online admin are in charge. An incredible benefit of this is that the organization can be configured and managed with specific use case or workflow requirements in mind. A challenge is that there can be a lot to keep track of, and for new admins, a bit of a learning curve. The below picks provide some tips and tricks for new and seasoned admins alike to make the most of your, dare I say almighty, role as ArcGIS Online administrator.

 

How to Be an ArcGIS Online Administrator

 

If you are just getting started with administration, my colleague Rachel Guttmacher's blog post, How to be an ArcGIS Online Administrator, is a must-read. It's a fun, conversational piece that covers some of the most crucial administration components including credits, member management, licensing, and security. 

 

Additional Resources:

 

 

Utilize Custom Administrative Roles to the Fullest

 

Another colleague of mine, Tyler Burns, recently wrote a great blog post on taking advantage of custom administrative roles: Lighten the Administrative Load in ArcGIS Online with Custom Roles. If you're looking to delegate specific administrative tasks such as managing members and content or organizing the website, the post provides directions and screenshots for exactly how to configure custom administrative roles to accomplish this. 

 

Additional Resources:

 

 

"AAA": ArcGIS Online Administration Automation - Video 

 

Kelly Gerrow and John Yaist presented this 20 minute talk on automating administration at the 2019 Dev Summit. For anyone administering a larger organization or with an interest in bolstering their automation skills, this is a recommended view. Topics covered are using the Rest API to query the organization history, and creating groups, users, and assigning licenses in batch with the ArcGIS API for Python. 

 

Additional Resources:

 

 

I hope the above picks were helpful for all the administrators out there! Let me know below any comments, questions, or if there are any topics you want to see in future posts. Thanks for reading, and be sure to keep an eye out for This Week's Picks - ArcGIS Enterprise & This Week's Picks - ArcGIS Pro!

 

See you again in March,

YouTube is an incredible platform for learning. From how to tie a tie (relied upon heavily for job interviews after undergrad) to how to play guitar, there are short videos on how to do just about everything. No surprise there are a lot of great how-to videos for ArcGIS Online workflows - the picks for this week highlight three new, relevant videos on using Living Atlas layers to analyze Australia's wildfires, uploading tile layers and tile packages to ArcGIS Online, and preserving relationships based on GlobalID/GUID fields when appending records. 

 

Use Living Atlas layers to analyze Australia's wildfires

 

Joseph Kerski recorded this timely how-to video on leveraging Living Atlas layers to analyze Australia's tragic wildfires. Joseph is a master educator (the video is tailored towards teachers and researchers); after watching the video I felt like I not only knew how to map wildfires, but also better understood spectral bands and satellite data collection.

Uploading tile layers and tile packages to ArcGIS Online

 

Esri Canada's Céline Doré created this helpful video on how to push tile layers and packages into ArcGIS Online. My favorite part (Céline does a great job explaining this workflow) was the demonstration of the sequence of geoprocessing tools to use in ArcGIS Pro to turn larger imagery layers into tile packages, and finally into hosted tile layers in ArcGIS Online. 

 

Additional References:

 

 

Preserve GlobalID/GUID relationships when appending records

 

After seeing several GeoNet posts with questions about appending records with relationships based on GlobalID/GUID fields (the central issue is that appended records are assigned a new GlobalID, becoming disassociated from their related records), I recorded this how-to video of a workflow James Tedrick designed to preserve relationships during the append. This is a workflow that shouldn't need to be used frequently but is good to have in your back pocket if you end up with two Hosted Feature Layers/Feature Classes with GlobalID/GUID relationships that need to be combined into one.

I'll admit, I'm on my phone more than I would like to be - but I'm not just scrolling Instagram and taking selfies. I regularly read story maps (which I should mention are mobile-ready by default), and I checked public safety apps habitually during last year's California fire season. Straightforward observation of the world around us indicates that I'm not the only one making good use of their unlimited data contract. And like me, most people are probably doing a lot more than scrolling Instagram. 

 

What if they were looking at an ArcGIS web app that you had built? What if you had configured it with mobile in mind and the UX/UI and functionality were excellent on a smaller screen?

 

The picks for this week may help change both of the above questions from rhetoric to reality.  

 

***Note: this post covers web apps accessed in mobile browsers through a URL, not native apps. To build native apps for iOS and Android you will need AppStudio for ArcGIS***

 

ArcGIS Experience Builder: Build Apps for Multiple Screen Sizes

 

ArcGIS Experience Builder takes advantage of modern web technologies to amplify Web AppBuilder's out of the box mobile capabilities. Crucial functionality is the ability to configure the same app differently for mobile and desktop. The Esri YouTube user "GeoDev" goes through some crucial steps in this video, from customizing widget layouts to different elements on the page so that your app looks great and performs on multiple screen sizes. Creating links between different pages is shown as well. Though the video is for Beta 1 it is still very informative.

There is a chance that if you’re reading this, you might have contacted Esri Technical Support before and spoken or emailed with one of my colleagues. It goes without saying that Esri Support Analysts are wizards at solving technical problems involving GIS, but what some folks don’t know is that they are also the engine behind the Support site’s Knowledge Base (KB). 

 

That’s why this week I want to highlight three new(ish) Technical Support-written Knowledge Base articles that get into some lesser-known ArcGIS API for Python and Arcade functionality.

 

Clone Hosted Feature Services between ArcGIS Online Organizations

 

“The best-laid plans of mice and men often go awry…” and suddenly, it’s a requirement to transfer Hosted Feature Layers, Web Maps, Apps and maybe even surveys and dashboards to a different ArcGIS Online organization. This would be a daunting task, but the ArcGIS API for Python’s Clone Items method makes it easier. This KB article (written by yours truly, I know - shameless plug) provides a Jupyter Notebook and standalone Python script code sample to get you started. 

 

Additional References:

 

 

Automate ArcGIS Online Hosted Feature Service Downloads

 

Unintentionally overwriting a layer or accidentally deleting a Hosted Feature Service are mistakes that many of us have made in ArcGIS Online. With the ArcGIS API for Python, it is possible to automate local backups of your Hosted Feature Services for when these situations unexpectedly come up. See the code sample in Munachiso Ogbuchiekwe's KB article.

Step-by-Step: Calculate a Field in ArcGIS Online with Arcade

 

In This Week's Picks - ArcGIS Online #3, I highlighted Arcade resources focused on pop-ups, symbology and labeling. To round things out, Hanushrie Gopalkrishnan's support KB article demonstrates how to use a simple expression to calculate a field based on the values of two existing fields.

Thanksgiving weekend had me thinking a lot about sharing. We share a meal; we share time with family and friends; we create shared memories and history together.

 

With sharing on the mind, the sheer number of hours I spend in ArcGIS Online meant it was only a matter of time before I began thinking about sharing data, maps and apps, and the powerful messages and stories that can be conveyed to a lot of people when these items are shared with the public.

 

However, there are some factors to think about before making your items accessible to everyone.  

 

The following resources describe best practices for layer and Web Map configuration for publicly shared items, discuss the nuances among public sharing options, and provide some suggestions for generating the most possible interest in your public maps.

 

An important note before the picks: It is the responsibility of anyone sharing layers, maps and apps publicly to check the data to make sure that nobody's private information is included. 

 

Blog: Prepare Content for Public Sharing

Important elements to consider before sharing items publicly include access to the content, accessibility, and the end goal of the map or app. My colleague Madison recently published an outstanding blog going through four crucial questions that help address the above aspects. My favorite passage: “Members of the public never have access to delete your maps and apps, but mistakes can happen in an organization with many members who have content administration privileges… for this reason, we recommend enabling delete protection for all content shared publicly (layers, web maps, and apps). Deleting web maps or apps is a permanent action that cannot be undone.”

 

Additional References:

 

 

Video: Prepare Content for Sharing with the Public

Take a closer technical look into some of the concepts that Madison presents through the ArcGIS Online team’s video demo, recorded at the 2018 Developer Summit. Specifically, there is a side-by-side comparison of Feature Layer and Tile Layer performance for public-facing applications, as well as the full workflow of enabling subscriber and premium content in a configurable app, a Web AppBuilder app, and a Story Map.

Blog: Captivate Your Audience with Apps

Creating a configurable app from your Web Map is a quick, straightforward way to provide a focused user experience for a public audience. This blog covers some templates that are great for public sharing, the importance of well-configured pop-ups, and organization branding. Quotable line: “Configurable apps in ArcGIS Online turn your web maps into shareable and presentable information products.”

Welcome to the third round of Product Advocacy’s completely unofficial, recurring GeoNet post!

In case you missed my first and second posts over the past month, "This Week's Picks" is a (loosely) biweekly blog where I share some of my favorite ArcGIS Online content with you.

--------------------

 



One of my favorite parts of my role is all the time I get to spend on GeoNet – you might have seen me answer a question or troubleshoot an issue in the ArcGIS Online space recently. Within this space I have noticed an uptick in the number of posts related to ArcGIS Arcade, the lightweight expression language that among other functionality unlocks pop-up, symbology and label customization across the platform.

 

So for the 11/12 edition of “This Week’s Pick’s – ArcGIS Online” I want to highlight some of my favorite Arcade resources that can assist with getting started on writing expressions or take existing code to the next level.

Understand Arcade:

I remember we had a unit on Arcade in my Master’s in GIS Program, and to be honest I was somewhat lost about what it was or where to start. In this video, Esri Canada’s Mark Ho provides a lucid overview of Arcade and how it can be used in ArcGIS Online – I certainly could have used this two years ago.

 

Additional References:

 

 

Smart Map with Arcade:

Take a deeper dive into the concepts that Mark presents though this Story Map on Smart Mapping with Arcade. Illustrated, step-by-step examples show how to create custom symbology, labels and pop-ups with Arcade. For further inspiration, there are also links at the bottom of the Story Map to live examples of Web Maps and Apps that have implemented Arcade.

Additional References:

 


Take a Deeper Dive with FeatureSets:

FeatureSets are one of the most popular Arcade functions because they unlock data across a Web Map (and after Arcade 1.8, across ArcGIS Online) for use in pop-ups and field calculation. Lisa Berry’s excellent two-part blog series takes a close look at how to ‘pump up your pop-ups’ using FeatureSets and Living Atlas layers.

 

 

Additional References:

I hope that the above picks provide some insight into the various ways in which Arcade can make pop-ups, symbology and labels come alive. Let me know in the comments below if there are any outstanding questions. Thanks for reading and stay tuned for This Week's Picks - ArcGIS Enterprise & This Week's Picks - ArcGIS Pro!

Welcome to the second installment of Product Advocacy’s completely unofficial, recurring GeoNet post!

 

In case you missed my first post a few weeks back, "This Week's Picks" is a (loosely) biweekly blog where I share some of my favorite ArcGIS Online content with you.

 

--------------------

 

We have seen numerous wildfires across California over the past couple of weeks. Two fires outside of Redlands rained ash on the Esri campus and had me refreshing Twitter to get news updates. When I needed to know the fire location and evacuation zones, I relied on ArcGIS Online Web Applications that I found through Twitter links.

 

Throughout the state, government agencies have done an incredible job of providing the public with similar apps that contain live-updated layers showing evacuation zones, emergency shelters, fire perimeters, road closures, and other need-to-know locations.

 

In circumstances like these it’s crucial that layers are up-to-date and accurate, and that apps load quickly for tens, if not hundreds of thousands of people.

 

ArcGIS Online is designed to handle heavy load. However layers, maps and apps must be configured properly to take full advantage of our geospatial cloud’s scalability. That’s why this week I want to highlight some content on maximizing the performance of heavily used, public-facing (often disaster response) applications. Many of these ideas are also applicable to everyday workflows.

 

Configure Layers and Apps for High Demand:

 

As citizens turn to ArcGIS Online-hosted apps to stay safe, it is paramount that the layer, map and app configuration is optimized to handle a high number of visitors. ArcGIS Online Product Manager Kelly Gerrow-Wilcox’s blog post goes into the nitty-gritty of how to configure high-demand apps.

Use Vector Basemaps by Default in ArcGIS Online:

 

Vector tile basemaps have been available in ArcGIS Online since December 2016 but are the default in Basemap Galleries only for Organizations created after the June 2019 ArcGIS Online update. Vector tiles outperform raster tiles for the following reasons: the smaller file size of vector tiles means faster load times, and vector drawing facilitates better adaptation to display resolution differences across devices. If you have an ArcGIS Online organization older than June 2019, this blog details how to make vector tile basemaps the default in the Basemap Gallery:

Create Hosted Feature Layer Views for Disaster Response Apps

 

A professor at my alma mater Johns Hopkins, Paul Doherty also advises the National Alliance for Public Safety GIS Foundation. In this five-minute video, Paul demos creating Hosted Feature Layer Views and discusses their importance in disaster response applications.

If you currently need GIS assistance with a disaster please contact Esri’s Disaster Response Program. I hope that the above selections provided some insight into the process of optimizing your layers, maps and apps for when they’re needed most.

I'm excited to introduce this completely unofficial recurring GeoNet blog post!

 

In my role as ArcGIS Online Product Advocacy Lead, I am continuously coming across informative, interesting, and inspiring content. Through "This Week's Picks" I hope to quickly share some of my favorites with you.

 

For this week, I want to touch on three topics I’ve seen a lot excitement about both here at Esri and within our user community.

 

New Map Viewer:

 

There are countless reasons to be excited about the New Map Viewer in ArcGIS Online. The beta is coming sometime this fall. Built on the ArcGIS API for JavaScript 4.x, the New Map Viewer is flexible, fast, and intuitive. Highlights and how you will access the beta can be found here.

 

Calculate a Weighted Average with Arcade:

 

For a non-programmer like myself, it’s always a little mind-bending (in a good way) to see different uses of Arcade and try to implement them in my own projects. My colleague Christopher Zielinski wrote this post showing how to use a weighted average within multivariate symbology - it's an elegant way to quickly visualize trends in your Web Map.

Introduction to Distributed Collaboration (Video Demo):

 

If you've thought about setting up Distributed Collaboration between ArcGIS Online and ArcGIS Enterprise, Esri Canada's two videos provide a succinct overview of how collaboration works, as well as a deeper dive into how items move across collaboration groups.
