Abstract.

We present an integrated technique for the completely automated digitization of raster maps. This technique considers in detail all three steps involved in digitizing raster maps; pre-processing, processing and post-processing. Current programs for vectoring maps using automated or semi-automated systems essentially carry out only one kind of operation; they follow discrete points along a curve. In our proposal, the automation problem is treated from a unified point of view, leading to the creation of software that is capable of recognizing a maximum number of cartographic images in raster maps. We propose some strategies for solving the problem, and illustrate with an example of an automated system to vector cartographic point objects.
