When looking at a map, whether for viewing or editing, a very common question is "where am I on the map?". Using ArcGIS for Windows Phone and the built-in Windows Phone device GPS, you can toggle a symbol on and off to display your location and the accuracy of the location. This functionality is available both when viewing the map and when editing features.
To display your location, follow these steps:
The GPS symbol displays on the map, showing your current location. The boundary around it shows the current accuracy. The map extent is updated to show the current location as the area of interest. The GPS is now in tracking mode, where it stays centered on the map. As you move around and the GPS symbol updates, the map pans, changing its extent to keep your location centered on the screen.
The app bar icon for me now shows that the icon is on in tracking mode, using the icon.
This turns off tracking mode on the GPS, and the me icon updates to indicate that tracking is now off, showing the icon. Now, as your position changes, the symbol roams on the screen. The map extent no longer updates to keep the GPS symbol centered on the map. The symbol can even leave the current extent.
