Compare Tool

Activate the compare tool by clicking the  button at the top right corner.

The compare tool can be used with orthophotos and surfaces. The most recent ortho in the map extend is set by default in both views. LandXML surfaces are NOT visible in Compare tool.

You can add an overlay layer that is a WMS or Maps -layer type.

You can do measurements also in the compare view.
