With configuration complete, you are ready for data collection in Esri Collector with orthmetric heights, directly with the field with your Trimble or Spectra Precision GNSS receiver.
- Select the desired web map in Esri Collector and proceed with data collection activities. This will immediately initiate the connection to the GNSS receiver as specified in the Location provider. The GNSS banner at the top will display the current accuracy, as well as the accuracy required (if configured).
- To view GNSS details, click the banner to open the GPS details screen. This will display a detailed list of current GNSS properties, including battery level for external receivers. Information presented is nearly identical between native receiver connections and location sharing (mock location) connections.
- To collect data, click the + button, select the feature subtype or template (if required), and fill out the attribute information. For point geometry layers, a position is already captured while for line and polygon geometry layers, controls are presented for vertex and streaming options. When you are complete, click the check mark in the upper right corner of the screen. You will see a feature detail view in the bottom half of the screen (which can be dragged up for full screen) and this will show the popup info configured in the web map, including the Arcade expressions for HAE and MSL.
- For online workflows, feature edits are made directly on the hosted feature layer while for offline workflows, feature edits are made in a local geodatabase that must be explicitly synchronized.
- Whenever you re-open a previously used web map, the last used Location provider will be used and a receiver connection will be attempted. If the receiver connection is not available, you will be alerted.
Note: If you need to make changes to the GNSS configuration in TMM during data collection, best practice is to close Esri Collector completely, make the changes in TMM, verify expected results in TMM, and restart data collection in Esri Collector.
