Do you or your colleagues know a little about Survey123, need to learn more, but dont know where to start? If so, we have created three learning paths to help you take you to that next level. We know there is already a LOT of information available to help you, and that the sheer amount can be overwhelming. To help focus your attention, learn paths are collated around a theme or a learning objective. They are made up of different types of content - some of the content has already been around for a while, some are new - and include videos, tutorials, blogs and formal documentation. For true beginners start with Try Survey123. In this path you'll use a survey first hand, build one yourself and take a look at the data that can be collected with a survey. Take your surveys further does just that. Learn how to make your surveys open to the public, use offline maps, connect to existing feature services to collect data and customize how your data is delivered to stakeholders. Creating your first few surveys can be straight forward: add questions, style and publish. But there's almost no limit to how smart you can make your form. Explore XLSForms for Survey123 will show you how to dynamically populate answers based on previous questions and data from external files, and how to translate your survey for multilingual use. These paths are hosted at Learn ArcGIS. Let us know what other Survey123 paths you would like to see created.   ... View more

Tile Package Kreator has been updated! Version 1.3 includes the ability to drag and drop shapefiles for delineating the bounding area of a TPK, browse Image Services for creating TPK's from, and generate TPK's with levels below 19. For a reminder on how to use the tool see Taking your maps offline with Tile Package Kreator or download the updated Guide. To download the app go to the Esri Marketplace. Esri Labs projects are developed by Esri employees and are inspired by our interactions with ArcGIS users like you. Esri Labs projects are free to use but are not official Esri products. These projects do not go through the rigorous software development cycle so they are not holistically tested, documented or supported by Esri technical support. Shapefile drag and drop Drag and drop a shapefile onto the map to create a boundary for export. Be sure to drag both the .shp and .prj file onto the map. Both line and polygon features are supported.  Image services In order to be able to browse image services, you must first change search query that is use by Tile Package Kreator. To change the query go to Settings. The default query is shown in the Search Query for Tile Service box:    (type:"Map Service" AND owner:esri AND title:(for Export)) OR (type:("Map Service") AND group:(access:org)) You can alter this query to suit your organizations needs. Don't worry if you get tangled up with the query, click Reset to Default to return to the default query. Levels below 19 Several services, like the World Imagery for Export service support additional zoom levels in some parts of the world. Tile Package Kreator now supports export of tiles from these additional levels, but we advise to proceed with caution.  The default maximum level is 21, you can increase this level in Settings, but we have observed regular failures to export beyond level 21. This additional levels also significantly increase the number of tiles that are to be exported. When using these levels consider a smaller extent. Time out non-responsive services There may be services in your organization that are currently not working as expected. Tile Package Kreator does keep trying to get a response from services that have export enabled. You can adjust how long your willing to waiting for a service respond on the Settings page. ...

The new GNSS Info sample, included in AppStudio 3.0 Desktop Edition, brings together the components in Qt and the AppStudio AppFramework that you can use to build an app that interacts with GNSS (Global Navigation Satellite System) receivers. Common features of this type of apps are: The requirement to browse and connect to a receiver Display a location on a map along with metadata about that location Presentation of available satellite information Presentation of key quality parameters that may indicate the usefulness of the data received Display a raw feed of the data coming from the receiver for troubleshooting purposes Each of these features are shown in this app on separate tabs. You may choose to use one or more of these tabs in your own app, or use this app as it is, to test out your own GNSS receivers with your hardware. What type of receivers can be used? This app will connect to, and display location information from, GNSS receivers that output NMEA sentences. For examples of recievers that we have tested with see GPS receiver support—AppStudio for ArcGIS | ArcGIS . Qt and the AppFramework can also read and write data to other bluetooth devices using the same components used in this app. For example, you can connect to a bluetooth printer using the same device discovery component and send data from your app to the printer for immediate printing. For more information on the key components in this sample refer to: DeviceDiscoveryAgent - http://doc.arcgis.com/en/appstudio/api/reference/framework/qml-arcgis-appframework-devices-devicediscoveryagent/ PositionSource - http://doc.arcgis.com/en/appstudio/api/reference/framework/qml-arcgis-appframework-positioning-positionsource/ SatelliteInfoSource – http://doc.arcgis.com/en/appstudio/api/reference/framework/qml-arcgis-appframework-positioning-satelliteinfosource/ NmeaSource - http://doc.arcgis.com/en/appstudio/api/reference/framework/qml-arcgis-appframework-devices-nmeasource/ Receiver detection This app can detect receivers that are connected to your device using: Bluetooth pairing – to connect to a receiver in your app you must first pair it with your device. Note that some receivers have a limit to the number of devices they can be paired to at anyone time. For example, the Eos Arrow can only pair to one device at a time, while Bad Elf devices can pair with up to 2 devices at a time. For information on pairing your reciever see Use a high-accuracy GPS receiver—AppStudio for ArcGIS | ArcGIS . USB/COM connection – A GPS receiver that plugs into a computer via USB is displayed in the app as a COM port. To confirm which COM port your device is represented by, look at the list of devices connected to your computer. For example, on Windows go to Device Manager > Ports (COM & LPT). TCP/UDP network connection – A TCP (Transmission Control Protocol) connection is bidirectional and has limited error handling. On the other hand, UDP (User Datagram Protocol) is one way only and has no error handling. Creation of a UDP connection requires the hostname and port of the destination machine (where you are running the app), while creation of a TCP connection requires the hostname and port of the machine providing the GNSS information to the destination machine. On the device tab, press to select a device. Next time you launch the GNSS Info app, it will attempt to automatically connect to the last device used. You can always return to the device tab and change which device you connect to.   Location display The location tab shows the current location on a map. If your device has network connectivity, an online basemap is used. A limited offline basemap is also available in the sample. Key metadata about the current location is displayed. The app also allows the user to change the units in which latitude and longitude are displayed. Use the location tab to confirm that the location reported from your hardware is the expected location.   Satellite sky plot The skyplot tab shows both a skyplot and a table view of the satellites reported by the receiver. Be aware that some receivers have a physical display that may sometimes display different values to this page. Other receivers have their own companion app that also may show different results. These differences are mostly likely attributed to manufacturer specific parameters and the way each manufacturer presents data from the receiver. The GNSS Info app displays the number of satellites in view, and the amount in use to calculate your location. There can also be satellites in view (or in use) that have no signal. This is usually a temporary response and should not affect the quality of a location displayed in an app. Use the skyplot tab to ensure you have positioned yourself or your hardware in the best location to capture a suitable position value.     Quality tab The quality tab lists common meta data available from a GNSS receiver. These are values you may choose to capture during data collection as attributes of your feature. Alternatively, you may use these to indicate the quality of the position to the user. For example, you might warn the user that accuracy values are greater than a prescribed threshold and disallow them to capture data.   Log tab The log tab shows a stream of the sentences that are emitted from the receiver. Different receivers output different sent ences. The presence or absence alone of sentences is useful for troubleshooting a receiver connection issue. The inspe ction of the presence or absence of individual sentences can also aid diagnosis of unexpected parameter results. For example, latitude, longitude and altitude errors are only calculated when the GST sentence is present. Not all receivers output the GST sentence. If the GST sentence is not available, then ‘No Data’ is reported on the quality tab for latitude, longitude and altitude error. Use the pause button on this tab to study the latest sentences. Use the delete button to clear the screen to make it easier to read new sentences.     Switching between the tabs of this app will display to you the continuous stream of data reported from the connected GNSS receiver in several ways: as text, on a map, as a graphical representation, and in its rawest form. You can choose which of these best suits your own app, or use this app to evaluate what information is available to you from your own receiver. ... View more
