Are there any tools or methods that allow QGIS analyze whether the lots/parcels have been untouched or developed, and return a "1" or "0" to a table or points layer or anything?
I was thinking more into simple shape recognition, like a driveway(2 parallel lines) or a rectangle (dwelling of sorts) or by colors: green/brownish(untouched), silver-ish (developed,) or by a differential of "most of area in one color" and a spot with a "different color". The lots-layer has an attribute table with areas, id, etc. and overlaid with Google Maps/Bing, etc. (see attached pic)
