Efficient techniques for telephone company line drawing interpretation

In this paper we present the idea of using customizable tools to develop systems to interpret telephone company drawings. These drawings are composed primarily of horizontal and vertical lines. By selecting the intersections as primitives, routines are developed to establish spatial relations of the primitives which are used to describe the structures. Another aspect that as presented is the benefit of using run length encoding to reduce the amount of memory and the processing time needed to process the large files resulting from scanning the forementioned drawings. Examples of the interpretation of telephone company distributing frame and front equipment drawings are presented.
