Our country is projected the technical development studies, constructed the digital maps, developed standards, established rules, and educated users during the first NGIS plan. This National Geospatial Information Infrastructure is proceeding with the program as arranged. In the second NGIS plan, our government try to construct the framework data for the maximization of GIS utilization. But National Geospatial Information Infrastructure included some problems from view of data framework particularly. In this paper, we make a comparative study of foreign countries, analyze the cause of our problem, and present the standards for Korean National Spatial Data Infrastructure.

Efficient extraction and update of imagery is a crucial element in establishing latest geospatial information in today's fast changing Information society. Provision of Quick Bird imagery, with 61cm resolution panchromatic imagery and 2.5m resolution multi-chromatic imagery is contributing greatly in the application field if high density geospatial information. This research have conducted digital plotting utilizing stereo images provided by QuickBird satellite and evaluated the accuracy through comparison and analysis with digital map results. It turned out that result has smaller error than standard deviation of scale of 1:5,000 set by the NGII. This proves that the production of digital map at scale of 1:5,000 is possible.

The major purpose of the present study is to gauge the general applicability of cadastral surveying and LiDAR surveying. LiDAR survey is the method which obtains Geospatial information of the terrain. We will get a most topographic models at Digital Elevation Model(DEM) using LiDAR survey data. Also, we will consider both the surface parcel partition and volume parcel as a part of Geospatial relationship model. This study will focus on enhancing the efficiency and analysis of continual cadastral map and LiDAR DEM. I would like to close by proposing that LiDAR surveying will contribute in cadastral surveying.

National Geospatial-Intelligence Agency(NGA) developed VPF in mid 1980 to digitalize military geospatial information. However, because VPF is very complicated system and was severly inefficient in producing, maintaining, and managing the data, VPF was required to be replaced by more efficient data format. These requests resulted in an integrated schema, and eventually VPF. The main idea of using FDB in the production of digital map of non-accessible area is to increase the accuracy. This research focuses on the production of high accuracy digital map by utilizing the FDB. The accuracy of digital map by FDB and by DGN was individually compared with 1m CIB imagery of the Korean peninsula. By analyzing 38 check points based on CIB, DGN showed RMSE of 52m X axis and 49m Y axis. FDB showed 15m in X axis and 13m in Y axis. These results show that the digital map produced using FDB has much higher accuracy than DGN based digital map.

This paper proposes neighborhood reduction techniques in local search of the customer decomposition subproblem in the Multi Depots Vehicle Routing Problem with Time Windows (MDVRPTW) by using geospatial relation among depots and customers. The neighborhood of the customer decomposition subproblem can be simply and well defined but it should include excessively bad solution candidates. Our techniques find such candidates by using information of the problem domain, geographical relation. We use our techniques in Tabu Search and evaluate the effectiveness in computer experiment.

본 연구에서는 시공간 제약뿐만 아니라, 데이터의 다양성에 따른 제약조건까지도 최소화하여 온라인상에서 지리정보 활용성을 제고하기 위해 기존의 국가지리정보유통망을 지리정보통합포털로 발전시키기 위한 방안을 제시하였다. 이를 위해 미국의 지리정보포털인 GOS(Geospatial One-Stop)를 모델로 하여 우리나라 국가지리정보유통망을 지리정보통합포털로 발전시키기 위한 모델을 수립하였다. 지리정보통합포털 모델은 개방형 분산프로세싱 시스템 구조에 대한 In 국제표준인 RM-ODP를 기반으로 하여 전사적 관점, 정보관점, 전산관점, 공학관점에서 수립하였다. 이를 통해 국가지리정보유통망을 기반으로 각종 지리정보 및 지리정보서비스에 대한 접근성을 제고함으로써 국가차원에서 GIS활용도를 높이는데 기여할 수 있을 것으로 기대된다.
