Field data collection workflow
TerraSitu's mobile app is designed to work offline for days at a time. This workflow covers the complete cycle from downloading data to syncing it back.

Before you leave
- Open the TerraSitu mobile app
- Go to Sync in the bottom navigation
- Download survey packages for each survey you'll be working on
- Verify the status shows Ready for fieldwork
Each package includes: form templates, GIS layers, map tiles, sampling units, species data, and stakeholder information.
In the field
- Open the survey — select your project, site, and survey
- Navigate — use the map to find your sampling unit or survey area
- Create observation — tap Add Observation. GPS coordinates are captured automatically
- Fill the form — complete the structured data form designed for this survey
- Capture photos — take photos directly from the app. They are automatically geotagged
- Save — the observation is stored locally and queued for upload
You can work for days without connectivity. All data is stored on-device.
After fieldwork
- When you have connectivity, open the Sync screen
- Tap Upload — observations upload automatically
- If two people modified the same observation offline, you'll see a conflict resolution screen
- Choose which version to keep for each conflict
What syncs
| Direction | Data |
|---|---|
| Down to device | Survey packages, form templates, GIS layers, map tiles, sampling units, species cache, stakeholder data |
| Up from device | Observations, photos, GPS tracks, time entries, sampling unit status updates |
