Concept

Between surveys, the field data collector may choose to be looking at a map screen rather than the standard menu. They can launch surveys from this map screen by:

  • Clicking on existing map features, or
  • Creating new features.

The resulting survey contains either a reference to the feature or the feature itself.

The map screen

The map renders data in the following formats:

  • MBTiles (raster)
  • Vector Tiles
  • GeoJSON
