Paper Abstract

Graphical representation of cartocraphic data consists of symbols assigned to physical entities, interconnections to denote spatial and structural relationships among such symbols, and text to describe and identify these symbols and interconnections. An image understanding system to extract useful information from geographical maps is proposed. Pattern recognition techniques are applied to identify geometrical forms of various symbols. For each valid symbol identified, a set of files is created to store pertinent structural information extracted from the image. These files, in conjunction with a knowledge base of geographic data, are used to answer simple queries related to the spatial organization of the objects in the map.
