GIS Tools is able to not only store the integrated information between attribute data and spatial data, but also analyze them. Most of GIS Tools support current information of land. However, lawsuit of right of possession as well as statistic of past data for land policy may need historical information. Therefore, in the paper, we designed the spatiotemporal operators what can handle the historical information. and implemented them. The spatiotemporal operators are used in the history management system of Cadastre and Cadastral map based on GIS. The historical information is generated in spatial operation of spatiotemporal operators and then the implemented operators provide a function to store the historical information, and handle them.

The Internet map service is word-wide trend and suggest to build up surveying control point management by mashup and API functions. In traditionally many surveyor used the record book. The result of mashup with cadastral control point and Web's map services as Daum and Google map was well matched which is transformed common points and should be useful manage the it and field recognitions.

The cadastral administration is centered around cadastral maps. It is increasing that demand of the public for effective administration and higher quality of service through the development of application program of cadastral maps maintenance. Geo-Spatial Information System which is based on the graphic database of Yuseong-ku, Daejon City and the attribute database about cadastral information has been developed for effective maintenance and use in the part of map editing, public land price management and multi-parcel based work. In this pi-lot study, pointing out difficulties of database implementation and many experiences in the development of application program will be used effectively for further expansion of the automation of the cadastral administration.

In these days, the attributes data recorded in computerization of cadastral maps is just written in its own format, not considered the relation with graphic data. Therefore, digital information linked attribute data to graphic data is necessary to be performed as fundamental data of graphic information and analysis of various spatial information. This study is to present the possibility of GIS application by constructing cadastral information related to graphic and attribute Information based on the cadastral map. Attribute information was constructed as a relational database form using data modeling and entity-relationship diagram. Thus, this study is expected to be used as a fundamental data for various public planning and design including the effective management of cadastral information and building parcel based land information system by presenting various spatial analysis and application methods.

Vectorizing for input processing of map is the most time and cost consuming task, and the quality of vector data depends on that processing result. Therefore, it is an important task to develop a good vectorizing system in the GIS. Thinning algorithm is the most important technology for deciding the quality of vector data in the vectorizing system. In this paper, as a suitable algorithm for map vectorizing we considered several algorithms that preserve topological and geometric characteristics, and have no distortion of the contour line. As a results, we implemented WPTA4 and well known thinning algorithm, and compared WPTA4 execution results with the others.

Due to the conversion from the existing address system to road name address system, the versatility of the road name address from the public and private sectors is increasing gradually. Therefor, the reliability of the road name address basic map, of the default data is also an urgent need, this means the accuracy of the data. But, road name address basic map is production time due to the use of different map accuracy is to fall, so is also the situation insufficient of utilization. This study Construction of identify each attempt by the road name address basic map and analysis the location accuracy of road name address basic map. As a result, the RMSE of cadastral survey results showed that appears lower than the RMSE of digital map survey results. The judgment can be utilized as the basis for the proposed improvements for the road name address basic map.

The human history has progressed closely related to land. Mankind started land administration as a tool of governance to make land the object of imposing taxation as well as developing the land administration as a concept of securing property rights. People have drawn boundary lines on the ground to form a land parcel according to the usage and/or ownership. Furthermore, the land administration has been developed as a registering system of cadastral records fer the public announcement of fixed boundary instead of changeable ground boundary. Currently the citizens demand the provision of accurate and diverse information on the land which is assessed to has high property value encouraged by the rapid development in the post-industrial society today. However, even though the fact that the Korean cadastral registers produced during the Land Investigation Project are still practically in use causes land-related disputes and promotes public mistrust because of the changed boundaries by parcel mutation, the expansion and contraction of map sheets and the quality deterioration and damage of map paper, but the ultimate resolution is not yet made so far. The distance difference between boundary points are compared and analyzed using TS surveying method in the research as a methodology to resolve the boundary inconsistency, the current problem of cadastral records. Consequently, I'd say that the new surveying method of registering the coordinates of real ground boundary has been regarded as more efficient than considering the matter on the map regardless of urban or rural areas.

Currently, 1/5,000 Digital Topographic Map covers the whole country with administrative boundary of Gu, while some region has already been constructed with 1/1,000 digital topographic map has legal boundary of Dong. Here, Dong in 1/1,000 scale represents the legal boundary which is used in the address most of time. Therefore, there is no administrative-Dong yet although it is very useful in various fields. In this study, we suggested a method to construct the administrative boundary extending to the level of Dong empirically. In addition, the practical application of the administrative boundary in GIS is discussed. Two methods are applied to construct the administrative boundary to the level of administration-Dong; using the edited cadastral map and the digital topographic map. When the edited cadastral map is used, some problems such as boundary discordance to superordinate administrative area is appeared. On the other hand, using digital topographic map showed simple construction processes and easy connection with other framework data. Therefore, it is recommended that the digital topographic map should be used in the construction of the administrative boundary. It would be useful as framework data in various industries and public operations.

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.
