Path surveying of autogenerated map (2014-10-25)

The hiking map of the entire Hvaler community/archipelago is getting closer, on this trip Tone & I checked the area near Bølingshavn on Kirkøy.

We found several nice paths we used to link together the open yellow areas of which 50-75% could be shown as symbol 212: Bare Rock on the final map. I am working on code to semi-automatically detect such rocky areas on orthophotos and convert them to proper OCAD vector objects, similar to what I've done with the vegetation on this map.
