Geo-spatial information system technology and cartographic modeling techniques were used as a way to Improve the land use planning process. Off-road vehicle(ORV) trails, timber harvest sites, timber haul mads and wildlife ruffed grouse habitats areas should be allocated together in the Wayne National Forest in the United States. Automated spatial cartographic models were developed to resolve the conflicts of the multiple land use allocation. The techniques of descriptive and prescriptive modeling made the multiple land use allocation efficient and effective.

정확하고 신속한 주택 통계를 도출하기 위해서는 관련 정보를 생성하는 여러 정보시스템들의 연계하여 데이터를 통합할 수 있어야 한다. 또한, 체계화된 업무프로세스를 수립하여 데이터의 중복이나 오류 등의 문제점을 해결할 수 있어야 한다. 본 연구에서는 국가정보시스템인 건축행정정보시스템(세움터), 주택공급통계시스템(HIS), 부동산실거래관리시스템(RTMS)을 중심으로 주택공급관련 프로세스를 분석하고 효율적인 프로세스 방안을 제시함으로써 향후 주택통계 업무프로세스 수립에 활용될 수 있을 것이라 기대한다.

임대주택에 입주하고자 하는 이용자들은 복잡하고 다양한 유형의 임대주택에 대한 정보를 쉽게 얻을 수 없어서 많은 어려움을 겪고 있다. 또한, 정부차원의 주택관련 통계 역시 수작업으로 인한 부정확성 및 관련 정보시스템들 간의 일관성 결여로 정책수립에 있어서도 정확한 정보지원을 제공받지 못하고 있다. 본 연구에서는 임대주택에 관련된 정보 실태 및 사용자 요구도 조사를 통해 임대주택 정보시스템의 설계 방향을 제시하였다. 추후 임대주택종합정보망이 구축될 때 제시된 방안이 활용되어질 수 있을 것이라 기대한다.

The purpose of this study is to present a standardized scheme for providing agriculture-related information at various spatial resolutions of satellite images including Landsat + ETM, KOMPSAT-1 EOC, ASTER VNIR, and IKONOS panchromatic and multi-spectral images. The satellite images were interpreted especially for identifying agricultural areas, crop types, agricultural facilities and structures. The results were compared with the land cover/land use classification system suggested by National Geographic Information based on aerial photograph and Ministry of Environment based on satellite remote sensing data. As a result, high-resolution agricultural land cover map from IKONOS imageries was made out. The classification result by IKONOS image will be provided to KOMPSAT-2 project for agricultural application.

Depending on the transportation, information and communication technology development, urban such as the superficial spreading and the changing structure of internal space of the organism has various shape and speed of the changes. In particular, the main cause of these changes is the development of the traffic and this transport system is having a close connection with land use. This study presents the results about characteristics and changes of noise on each land use zoning. Therefore the result shows that the measured data could be used to evaluate noise distributions on urban land use and then make up the basis process for producing noise maps of land use zoning.

In this paper an attempt has been made to classify Asia land cover considering climatic and vegetative characteristics. The sub-class clustering based on the 13 MODIS land cover classes (except water) over Asia was performed with the climate map and the NOVI derived from SPOT 5 VGT D10 data. The unsupervised classification for the sub-class clustering was performed in each land cover class, and total 74 clusters were determined over the study area. Via these clusters, the annual variations (from 1999 to 2007) of precipitation rate and temperature were analyzed as an example by a simple linear regression model. The various annual variations (negative or positive pattern) were represented for each cluster because of the various climate zones and NOVI annual cycles. Therefore, the detailed land cover map as the classification result by the sub-class clustering in this study can be useful information in modelling works for requiring the detailed climatic and vegetative information as a boundary condition.

This study examines the unique characteristics of the parcel identification number especially in developing the Korean land information system(KLIS). There are several limitations in establishing KLIS in terms of the location identification. Therefore, it is necessary to develop the appropriate parcel identification number system in Korea including the road identification systym and the three dimensional parcel identification system. The exact parcel bounary also needs accurate surveying and registration.

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.

In this study, soil moisture and evapotranspiration were calculated throughout South Korea using the Korea Land Data Assimilation System(KLDAS) of the Korea-Land Surface Information System(K-LIS) built on the basis of the Land Information System (LIS). The hydrometeorological data sets used to drive K-LIS and build KLDAS are MERRA-2(Modern-Era Retrospective analysis for Research and Applications, version 2) GDAS(Global Data Assimilation System) and ASOS(Automated Synoptic Observing System) data. Since ASOS is a point-based observation, it was converted into grid data with a spatial resolution of 0.125° for the application of KLDAS(ASOS-S, ASOS-Spatial). After comparing the hydrometeorological data sets applied to KLDAS against the ground-based observation, the mean of R² ASOS-S, MERRA-2, and GDAS were analyzed as temperature(0.994, 0.967, 0.975), pressure(0.995, 0.940, 0.942), humidity (0.993, 0.895, 0.915), and rainfall(0.897, 0.682, 0.695), respectively. For the hydrologic output comparisons, the mean of R² was ASOS-S(0.493), MERRA-2(0.56) and GDAS (0.488) in soil moisture, and the mean of R² was analyzed as ASOS-S(0.473), MERRA-2(0.43) and GDAS(0.615) in evapotranspiration. MERRA-2 and GDAS are quality-controlled data sets using multiple satellite and ground observation data, whereas ASOS-S is grid data using observation data from 103 points. Therefore, it is concluded that the accuracy is lowered due to the error from the distance difference between the observation data. If the more ASOS observation are secured and applied in the future, the less error due to the gridding will be expected with the increased accuracy.
