Soil maps. Automatic digitization of polygonal coverage with attributive data.

An example of attributed polygonal coverage forming. Material specifics - badly worn-out state and dark polygon filling poorly distinguishable from the color of polygon boundaries. The examples includes preparing of a set of images, extraction of polygon boundaries and their cleaning from remnants of filling, automatic vectorizing, line filtering, and line form optimization. Final debugging of extracted polygon boundaries is expected to be done with editing tools.
