After defining MDC settings, tap on the Form button and start collecting data.
Populate fields with data and tap Send button.
Collected data will be visible in the Mobile Data Collection Portal and Map Editor.
- Projects – switch and filter forms without having to go to Settings tab
- GPS/Pinpoint – locate the mobile device using GPS or Pinpoint.
- Show on the map – show the current location of the user on the map.
- Accuracy indicator – shows the precision of GPS location.
- Form – populate the fields with data.
- Send – send the data to your map or project.
- Queue – pending data before it is sent to the map or project.
- Map – review your project or map on the field.
- Settings – general MDC settings.
Note: location accuracy will depend on GPS precision on the mobile device and on satellite availability. To define location more accurately, use the Pinpoint tool.
Note: if you delete data from the queue, it will not be sent and the data will be lost!

Open Queue, tap the feature, check and update all data and tap Send again.

This message indicates that is not possible to reach data source in which data should be sent. This means that it has been deleted or renamed.
Data source of each layer is stored inside Database Manager. If it is deleted, it will not be possible to collect data with MDC in that project.
If the data source is renamed, it is necessary to change it to the original name and refresh the project.
