AMUS-an automatic map-understanding system

Abstract

The main obective of automatic map-understanding system (AMUS) is to automatically recognise and extract various themes present in a map and input them into a geographic information system. This paper presents the details of automated text string separation from linear features. The algorithm used is relatively independent of changes in the text font, size and also orientation invariant. The system outputs two images, the text strings and the graphics information. Then the characters (in the text string file) are recognised by applying artificial neural network techniques. Experimental resuults are presented in the paper.
