Abstract

This paper presents a map interpretation system for automatic extraction of high level information (such as parcels and their attributes) from the scanned images of Chinese cadastral maps. Our map interpretation system consists of three main components: text/graphics separation, parcel extraction, and rotated character recognition. The techniques of text/graphics separation and character recognition are robust to the rotation and writing style of character. Another advantage of our separation algorithm is that it can successfully extract character connected to graphical line
