Editable layer on the map

 

Layers without a corresponding Edit button are not editable in TopoLynx topoXplore.

 

Layers are not editable due to one of the following reasons:

1. Editing of the layer type is not supported in TopoLynx topoXplore (image layers).

2. The layer is read-only. Vector layers can be read-only if the file permissions are set as read-only.

 

Locked layer

Not unlockable layer: raster layers and protected DMP layers

 

Lock: locks the active layer

Edit: edits the active layer

Point info: can be set to a point feature layer which collects attributes for vertices during a GPS measurement in a line or polygon feature layer
