도시정보체계에 있어서 토지이용 모형화를 위한 자료기반에 관한 연구

도시정보체계에서 토지이용 모형화에 필요한 자료기반을 연구했다.

According to the development of economy and industry, population density are increased in most urban of Korea. Therefore many fields which are related to traffic, landuse house, enviroment and water surpply etc. caused various problems. These problems are results which are occured by characteristics of data systems and review function which urban have. The highest increasement of data and informations make difficults in decision making. Therefore urban information systems to solve reasonably all problems of urban of which have the complex factors are required. In urban information systems, landuse are very importants with traffic information.

Landuse model is required for the effectible landuse, first of all, data transformation and data base have to be studied in its model. Informations for the landuse planning are different from informations for general administrative affairs in many field. One of them is a spatial display of data. Aims of this study are as follows : First is review of urban information for landuse modeling. Second is decision of data size and attribute. Third is transformation. Fourth is a construction of system of analysis and evaluation and lastly this study groped method which planner and decision maker can predict spatial and geographical phenomena.

The results of this study are as follows: First, database for urban information system must be efficiently estabilished with up to 1/25,000 scale for decision making and up to 1/1,200 scale for manipulation and management. Second, in case of building up database for urban information, the classes of attributes are various. So these classes must be systematization for mapping. Third, information of positions for urban information system needs an Oaccurate cadastral map at the execution stages. Then digital cadastral map must be applied with in database, because the cadastral map produced in our country isn't accurate.

The last, the model of land use having vanous purpose must consider the technical quantification and weight for the size of grid cells and the interval of buffers to be used in multipurpose.
