FEATURE EXTRACTION

Extraction of structural lines comes after the classification is done. Structural line represents the lines of the edges and the middle of motorway, the lower and upper edges of the curbs, the edges that define the accompanying channels etc. When structural lines are defined we continue drawing other spatial entities such as: white lines on the road, pedestrian crossings, bicycle paths, objects, bands, traffic sign, trees, fences, borders of different cultures, like arable lands, orchards, vineyard, meadow, yard etc.
