Control stations managed by national and local governmes are associated with other survey work and constructing geography information and they are important assets in the national level as the positional standard of the country. Since these control points are managed as some type of register and the control points could not be easily updated due to the loss of control stations from construction work or urban development. Therefore, the users could not understand the present situation of the changed control stations. In this background, the aim of this study was to develop control station management system which the managers can use to efficiently maintain control points and to support the usage of the survey control points. For developing this system, we have designed input, update, network, analysis and statistic functions, and have constructed the system using Mapobject as main engine with other languages such as Visual C++ and Visual Basic. The graphic data used in this system are 1/5,000 digital map and digital cadastral map, and the attribute data of each control station are point name, map tile name, longitude and latitude coordinates, TM coordinates, surveying data with the format of year-month-day and control situation photos and so on. In the result of constructing this control station management system, we could achieve integrated management of graphic, attribute and positioning information of each control station.

The land under Japanese-type names remains in the Korean cadastral record as an official register due to land exploitation, land and field survey programs, and the forceful name-changing system of Japan during its colonial era. This research aims to find a measure to survey and organize such land. Research details are as follows. First, this research put together the purpose and status of land exploitation in the Japanese colonial era. Japan wanted to reduce its population through agricultural emigration of the Japanese and increase food supply by producing more crops in Joseon. Therefore, land of three southern provinces, the breadbasket of Korea, was intensively plundered. Secondly, this research organized how Joseon people changed their surnames into Japanese-style ones. The initially voluntary name-changing system became mandatory and about 3.22 million households (79.3%) reported the change of their names. Thirdly, this research established a process to survey land under Japanese-style names. Fourthly, this research yielded visible outcomes as a result of the pilot program. Especially, it revealed 718 lots as land under Japanese-style names and 8 lots as land under the names of Japanese. Fifthly, this research presented internal & external collaboration and cooperation measures for surveys.
