Hello Robert,
I am sorry for the trouble but I removed the widget in order to take some screenshots. It is back in now if you can check it. The layer that has mensuration capability is the ForestFire (preliminary assessment) one.
Also, I have a problem with GeoLookUp Widget. It says that it has enriched the csv points with info from all layers (ForestFire, Slope, Aspect, Corine 2012), but it only uses ForestFire and Corine 2012. Any ideas?
Emmanuel
