Automated Map-Drawing Digitizing Technology Based on Scanner Input

An original technology and techniques to digitize large-size maps is presented in the paper. Difficulties in automatic solution of this task made us to produce a wmbinedautomatic-interactive technology which includes together with automatic vectori7ation of map layers and automatic object recognition also interactive object digitizing and manual object digitizing based on image context. Such combination allowed us to reach an acceptable ratio between quality, time and automatization level of the digitizing process. Another advantage of the developed technology is that it allows to digitize large-sizc maps under limited computer memory resources. The techniques and algorithms realizing such a technology are shortly described in the paper.
