Emergence of Geographical Information Systems (GIS) has facilitated map acquisition and utilization to a great extent. This paper presents novel methodology for the extraction, representation and analysis of objects and symbols from topographic sheet that are geographically important as well as their spatial interrelationship. The method exploits various image processing tools suitable for specific objects and symbols on the basis of their geometrical and morphological attributes. The output is presented as a spatial database for further query processing and hence is suitable for GIS applications. The methodology is found to perform quite satisfactorily.
