Abstract :
Describes a new system for the reconstruction of geometric map elements as developed in the Dutch TopSpin-PNEM (Provinciale Noord-brabantse Energie Maatschappij) project “Knowledge-based conversion of utility maps”. Vectorized map elements coming from an image interpretation system are reconstructed and reference elements are aligned w.r.t. a base map so that geometrical inference is made possible in a geometrically correct topographic base map. This is done using a map correspondence between the utility map and the base map based on mutual topography and relational information supplied by a map interpretation module, applying a novel conflict resolution strategy. With the map correspondence, the relations and several object-specific functions, the map elements are relationally and geometrically correctly reconstructed
