The purpose of this study is to propose and verify a spatial network construction method that integrated roads and subway lines to improve the predictability of the urban spatial analysis model. The existing axial map for urban spatial analysis did not reflect the subway line that serves as an important moving space in modern cities. To improve this axial map, proposed a Ground-Underground Spatial Network by integrating the underground spatial network with the axial map. As a result of the integration analysis, the Ground-Underground Spatial Network(GUSN) were similar to the movement frequency. Correlation of GUSN was 0.723, which showed higher explanatory power than correlation coefficient of 0.575 in axial map. The result of this study is expected to be a theoretical basis for constructing spatial network in urban space analysis with subway.

By the progress of Information Technology, spatial data have been recognizes as one of essential infrastructure. Now for the near future needs of urban simulation, management, u-City construction, etc. MOCT(Ministry Of Construction & Transportation) have been driving to construct the 3D Geo-spatial Data as one of National Spatial Data Information on a base of 2D GIS(Geographic Information System). In this study we tried to analysis the demands and the optimum implementation method of 3D Geo-spatial Data in local governments. As the result of study, the plan to utilize 3D Geo-spatial Data and to carry out its utilization, and the advanced vision of 3D GIS in for the public affairs of Local Governments and private business scope were proposed.

The aim of this study is for performing the efficient and systematic facility maintenance management by using 2D CAD data and the technique of updating spatial DB. The existing system of the facility maintenance management and the performance is not properly made out utilizing the information about the construction drawings. Moreover, the management of the DB renewal, which is about the information of construction drawing, is not carried out properly Furthermore, this study draw the conclusion on the effectiveness of reducing maintaining active by the lack of the interior and exterior location information. This study suggest the method of the efficient maintenance management of facilities by using the technique of updating spatial DB and the facility location information.

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.

The environmental survey in advance in the construction works is very important for planning and designing as well as the service of field survey before carrying out construction. The topographical application of spatial information coupled with USN is the very economical method for the survey and research every processing stage of construction field in advance. Therefore the execution of very important role for environmental planning and fundamental designing of construction reduces the unnecessary trial and error through the environmental survey in advance. In this research the environment of existent construction field is transformed to that of digital spatial information by fusing the sensor network with wireless technique on the base of spatial position. In addition, the sink sensor cumulates the environmental data measured from each USN sensor using small wireless environmental sensors installed at the construction site and changes of various environmental data at the present constructing site are able to be monitored at 3-D topographical space in real time by using the method for transmitting the image of PC output based on TinyOS.

Spatial data is becoming very important as a medium that connects various data produced in smart cities, digital twins, autonomous driving, smart construction, and other applications. In addition, the rapid construction and update of spatial information is becoming a hot topic to satisfy the diverse needs of consumers in this field. This study developed a software prototype that can match the position of an image-based 3D building model produced without Ground Control Points using existing spatial data. As a result of applying this software to the test area, the 3D building model produced based on the image and the existing spatial data show a high positional matching rate, so that it can be widely used in applications requiring the latest 3D spatial data.
