A placemark marks a position on the map. At its most basic, a placemark is indicated by a default icon and stores geographic location.
Adding a placemark
To add a placemark, pan to a position on the map centered by the crosshair and tap the Add Placemark icon. Users will be shown the Placemark details screen before a placemark is actually created. This screen (shown in the second image) allows users to specify the name of the placemark, specify the symbol, attach pictures, and set any attributes. Once you have set the necessary information, tap Submit in the upper right corner, and the placemark will be created.
Tap the placemark label to see details about the placemark. On the Edit Map Feature screen, you can change the placemark title, icon, enter a description, add photos, edit the location coordinate, and edit attribute schema. For more information about attribute schemas, please see this article located in the Advanced Data Collection section of the Help Centre.
Moving a placemark on a map
To move a placemark on the map, tap and hold a placemark, move it to another position and release it.
Deleting a placemark
Tap the Information icon on the placemark label to see details about the placemark. Tap the menu icon in the top right corner and then select delete from the menu.
