Possibilities of automated georelief segmentation for the requirements of Geomorphologic information system (GmIS)

Original language description

Four different algorithms based on searching for discontinuities in fields of derived morphometric characteristics were implemented and tested for automatic delimitation of boundaries of elementary forms of georelief. The best results came from an algorithm based on the Canny edge detector and this was used for further testing. This algorithm produces segments of the boundaries of elementary forms. In this paper strict rules are specified for delimiting the areas of elementary forms from these segments.Application of the Canny-based algorithm should use data smoothed to reduce the density of edges detected. Ways for creating suitable surfaces are compared here.
