Most of the currently available cadastral maps conserved in the Land Administration Office are drawn on paper. They are apparently ineffective for both maintenance and updating. Moreover, after constant consultations the maps would become mutilated and blotted gradually. In this paper, we develop techniques for transformations of cadastral maps from analog signal into digital data. There are substantial advantages with the resultant maps including effective storage, easy maintenance, expeditious retrieval, and fast computation. These advantages can be further extended by connecting the databases of maps to the networks or incorporating the databases into GIS systems. There are potential challenges to our tasks. It is inevitable that pieces of information may be lost during map transformation. Furthermore, it is demanded that the transformed maps would preserve as faithfully as possible the information of the original maps. The experimental results demonstrate the applicability of the proposed techniques.
