Much efforts are being process at many ways for digitization cadastral maps that will be the base map of Parceled Based Land Information Systems. But, current digitizing systems need too much time and cost digitizing about 720,000 cadastral maps. That's way we develop new digitization system for cadastral maps by using scanning and vectorizing methods. In this paper, we treat scanner test and vectorizing program that are the most important parts of new digitization system for cadastral maps. we analyze needs of Korean Cadastral Survey Corporation, and discuss algorithms and functions of developed programs. Using newly developed scanner test program, user could test various scanners, and use inexpensive scanner if it satisfy the accuracy needed. And vectorizing program will reduce much time and cost, because it is designed and customized practically to he adequate to cadastral maps and to improve work speed, accuracy and usage.
