Most spatial data handled in GIS is two-dimensional. These two-dimensional data is established by selecting 2D aspects form 3D, or by projecting 3D onto 2D space. During this conversion, without user's intention, data are abstracted and omitted. This unwanted data loss causes disadvantages such as restrictingof the range of data application and describing inaccurate real world. Recently, three dimensional data is getting wide interests and demands. One of the examplesis Database Management System which can store and manage three dimensional spatial data. However, this DBMS does not support spatial query which is the essence of the database management system. So, various studies are needed in this field. This research designs spatial relationship that is defined in space database standard using the three-dimension space model. The spatial data model, which is used in this research, is the one defined in OGC for GMS3, and designing tool is DE-9IM based on Point-Set Topology blow as the best method for topological operation.

In this paper, a 3D position tracking algorithm for a moving objects using a stereo CCD cameras was proposed. This paper purposed the method to extract the coordinates of the moving objects. That is improve the operating and data processing efficiency. We were applied the relative orientation far the stereo CCD cameras and image coordinates extraction in the left and right images after the moving object segmentation. Also, it is decided on 3D position far moving objects using an acquired image coordinates in the left and right images. We were used independent relative orientation to decide the relative location and attitude of the stereo CCD cameras and RGB pixel values to segment the moving objects. To calculate the coordinates of the moving objects by space intersection. And, We conducted the experiment the system and compared the accuracy of the results.

Today, ever growing population density in Seoul or areas near Seoul is problematic. To overcome the problem, the government tries to construct so called, 'New-towns'near Seoul to spread out the population over larger areas. But building new-towns created another problem of traffic between Seoul and New-towns. It can be solved if more public transportation systems such as urban railroads are constructed. In order to succeed in urban railroad construction, we have to make a perfect plan through in depth research on characteristics of the urban train and the construction site. In this paper, we propose a method to design the Decision Support Systems(DSS) using Geographic Information Systems(GIS) and Spatial Analysis for the planning of urban railroad construction.
Development of LiDAR and SBES data Merging Program for Calculation of Water Volume

LiDAR(Light Detection And Ranging) can make terrain model where above the ground and the mixed data between SBES(Single Beam Echo Sounder) and SSS(Side Scan Sonar) can make terrain model where bottom of water. So this research suggest that how to merge data which are got ken different devices and we developed the software which can display 2D/3D graphic and water volume calculation. And we compared accuracy between the commercial software'Surfer'and LiDAR and SBES data Merging Program.

Journal of Korea Spatial Information Society, volume 13, issue 2, 2005, Pages 167~183
Wetlands are a transitional zone between aquatic and terrestrial ecosystems, and a habit for the various biospheres. The main purpose of this study is to suggest a new technique that establishes the management districts of inland wetlands. To establish management districts of sub-watershed units, this study used the BurnDEM techniques. The management district resulted form this study are assessed its effectivity using an overlap of inland wetland map and sub-watershed maps classified by 18 sub-watershed. The result of this study could be applied to build a national inland wetland database.
A Study on the Algorithm of Address Symmetric using Cadastral Map
Yoon, Hun-Hoo ; Jeong, Jong-Chul ;
Journal of Korea Spatial Information Society, volume 13, issue 2, 2005, Pages 185~194
The purpose of this study is to create address standardization through an Algorithm based on cadastral maps, as well as to establish a method of transforming one information area to all of the domestic areas in relation to the geographic information system. To do this, it analyzed the current level of e-government cadastral data and their integration strategy with addresses of both the administrator and the cadastral data. This study will provide a more efficient method for co-operative work between private sector and public sector. In addition, we can expect that the information strategy of local government will become more active.
