This panel contains Map specific settings.
New layer type: this is the preferred format for a new layer.
Geometry decimals: this is the default precision to store the geometry in a new layer. Lower value requires less memory to store the geometry but the spatial accuracy is decreasing too. Value of 2 means [cm] accuracy, value of 3 means [mm] accuracy.
Vertex snapping: globally turn on and off the snapping. If snapping is enabled, then the new vertices will snapped to existing geometries (points, polylines, polygons) during drawing or vertex editing.
Show GNSS log: controls the display of the GNSS receiver track log.
