Landuse information is base data being applied as common database in the process of executing urban project service and is very available. But, the progress of business on landuse information building is deficient yet. In this study, we'd like to deal with landuse information projet that is the base of urban project, many landuse information building and the method of extraction of efficient second-information. Also, we built system to apply actively landuse information for urban projectors. And, we'd like to present the model on urban landuse classification system that wouldn't be standard yet by studying the method of urban landuse pattern using landuse in-formation being built. Also, we can evaluate if the model of urban landuse pattern comes up to present landuse. We can expect it is a base data by extracting unsuitable area from present landuse efficiently when we construct landuse project.

도시재생을 효율적으로 수행하기 위해서는 시간 공간속성을 가진 지표데이터를 기반으로 한 종합적인 분석이 가능한 진단체계의 구축이 필요하다. 본 연구에서는 이러한 진단체계 구축의 일환으로 도시 재생 대상지 선정 모듈을 개발하였다. 대상지 선정방식은 인구사회, 산업경제, 물리환경 부분별 진단지표 DB를 구축하고, 각 부문별 조건에 부합되는 지역을 선정하도록 하였다. 기준으로 설정된 조건 이외에 상세 분석을 위한 지표 조합방식을 도입하여 상세분석이 가능하도록 하였다.

A cadastral map that is base map on Land Information System is divided by two categories, graphical and digital cadastre. And digital cadastre can be displayed with location coordinates of nodes that depict parcel boundary on digital cadastral records. The transformation of digital cadastral records means that imported text data of node coordinate would be transformed into system data. This study was implemented to search reasons of errors resulted from transformation of graphic data and then to analyze the accuracy in terms of Position and area. For this, checking of software used in Geo-Spatial Information System was implemented at first and it was found that the accuracy is up by using double precision in coordinate transformation. On the position accuracy the errors at nodes was erased during making topology and the errors did not effect other nodes. On the area may the area errors because of being in error limit of allowable area had no problems in using of system.

As the city grows in population and size, land-use plan increasingly becomes a crucial element in developing a city-wide plan. In the process of developing the land use plan, identifying the present conditions and predicting the future conditions are the most important steps. That is, to understand the phenomena of land-use activities as well as to manage uses of the land efficiently require the comprehensive land use information system. This study intends to construct the land use database utilizing the Cadastral Map and Registered Building Data and to examine and suggest the application areas of the database. The database was constructed with those of Busan Metropolitan City. Using the established data, it shows how to use the database to identify the present conditions in Busan.

The purpose of this research is to develop system and to establish methodology for managing spatial Database in Land Management Information System(LMIS). Spatial Database which is used by a various public department such as parcel survey and registry, land use planning and Land value appraisal in local government, is composed of parcel map, topographic map and zoning map. Spatial data has been constructed and managed by various department and then hard to maintain accuracy and coinsistency. So, it is important to establish the basic data management concept that source data(ex : parcel map, topographic map, zoning map, etc.) should be managed by responsible department. at the same time, application data for bussiness (ex : individual parcel price map) must be recomposed from base map by it's own objects. This is, Spatial data management system (SDMS) should be designed, developed according to this concept for managing consistency among data, reducing construction and management cost of database. Our SDMS was developed based on Open LMIS middleware architecture using OpenGIS CORBA specification for standard interface, RUP(Rational Unified Process) for development methodology, UML(Unified Modeling Language) for system design and VisiBroker, C++, CAD system for system implementation.

For reasonable planning and decisions, spatial Planners should gather and analyse land use information which includes lots, zoning, population, households, buildings, usage, and etc. This study aims to define the demands of land use information for spatial planning. From literature reviews, case studies, and survey, this study shows those findings as following. First most spatial planners suffer from the difficulty of gathering land use information. Second, the priority order of the information could be shown by survey. Third, the unit and renewal period of the spatial information could be defined. Those findings could be a base of information systems for spatial planning.

세계적으로 세계측지좌표계의 도입이 확대됨에 따라 우리나라도 2001년 측량법의 개정을 통해 현재의 지리정보 좌표계변환을 위한 노력을 시행하고 있다. 이러한 측면에서 본 연구에서는 세계측지좌표계 변환방법론, 변환사례 등을 검토 후 한국토지정보시스템 데이터를 대상으로 시범지역을 선정하여 변환실험을 실시하였다. 그 결과 변환 후의 데이터는 국가GIS활용 및 업무지원을 위한 참조적 데이터로서 충분히 이용이 가능한 수준으로 도출되었다. 하지만 한국토지정보시스템 데이터의 세계측지좌표계로의 변환을 위해서는 각 지역별 변환계수를 산정할 필요가 있으며, 지적데이터가 가지고 있는 다양한 원점을 통일원점으로 변환되어야 할 것으로 판단된다. 또한 마지막으로, 기존의 지적데이터가 가지는 다양한 문제점을 그대로 내포하는 수준으로 변환되었다. 따라서 한국토지정보시스템의 세계측지좌표계 변환을 위해서는 본 연구의 결과를 기초로 하여, 더 많은 대상지역에 대한 변환을 통해 오차와 오류의 유형별 원인 분석 후 한국토지정보시스템의 세계측지좌표계 변환의 체계적이고 계획적인 전략을 수립할 필요가 있다.

For the exact status of the land such as land cover classification and land use classification, feature classification system has been utilized in several organizations and agencies. However, those classification systems are limited to detection of land change and it's also not suited for the extraction of land changed. In this study, we would proposed a standard feature classification system which presents both in natural and artificial change of land effectively. Based on comparison and analysis of domestic and foreign relevant feature classification system, we proposed a standard feature classification system. In order to validate the applicability of the proposed feature classification system, we evaluated the accuracy with using automatic feature classification based on supervised classification and pre-knowledge hierarchical classification.

Urban land use planning is the most important core-part, and it is the start and synthetical plan of the other part, in the urban planning. For the desirable urban land use planning draw out the spatial locational character and change of urban land use. The propose of tills study is building methodology of Parcel-based Urban Land use Information Svstem(P-bULlS) and it's apphcation methodology that can be used urban planning or land use planning. To this end, each and all of the land parcels of Kangnam area was analyzed. P-bULIS should be able to easily analyze the spatial locational character and change of land use in the region. And It should be able to the qualitative, quantitative and spatial analysis, and spatial multi-variate statistical analysis can be done at relatively low cost by linking the software of statics to P-bULlS.
