Abstract

The topic of this contribution is a matching between property borders of cadastral maps and field borders identified in satellite imagery (Landsat TM). For reasons of efficiency, the search space for the matching is spatially limited. Sufficient contextual information in a small spatial environment, therefore, is of paramount importance. The short edges of lots of long and narrow fields cannot be extracted in the same go as the well defined long edges because they are perceived edges rather than real step edges. A two step algorithm is needed for their extraction. Perceptual and conventional edges can be combined to supply the necessary local contextual information for a robust and efficient matching to take place. The matching algorithm is a refined version of probabilistic relaxation.
