Abstract (Summary of the Work)

With the ermergence of Geographical Information Systems (GIS) as a means for representing and storing Cartographic data on the computer, Map Acquisition and Map Recognition have become hotly pursued topics, both by the industry and the academia. The present report gives an account of a novel methodology followed in the extraction of features and their recognition from topographic maps. The method proceeds by separating the map into its constituent layers and then attempting to recognize the features in differen layers on the basis of feature-specific geometrical and spatial attributes. Text strings have also been separated. The output is in the form of a 'E-Map' that is vectorized and hence suitable for use by GIS. The methodology has been observed to produce recognition rates in excess of 90%.
