Abstract
The Cadastral map is a basic data that prescribes lot numbers, the
classification of land category, and the boundaries and ownerships of
land parcels. In Korea, the government has tried to digitalize
cadastral maps and inputted the attribute informations of cadastral
maps. But, the efficiency problems have been raised, because the
cadastral services mainly depend on the manual works. Also, the figure
informations of cadastral maps were not digitalized that there have
been many problems in establishing the efficient land information
systems.
In this study, we developed the hybrid vectorizing software to
enhance the deficiency of the analogue methods and to ensure the
accuracy of the cadastral maps. The hybrid vectorizing adopts a
screen-digitizing method as a prototype and automates the procedure of
searching the intersection of lines with efficiency. Consequently, in
the aspect of the accuracy, there is no difference with the
screen-digitizing method because the hybrid method is based on the
screen-digitizing. In the aspect of the efficiency, we can input the
neatline layers at regular intervals and the deformed neatline layers,
and shorten the data input time.
