In the past several years there has been relying on USA fur the resource of global positioning data in the pluralistic GNSS environment(Galileo, Post GPS, Quasi-Zenith Satellite System). For this reason, we should make a decision which strategy for research is carried out. According to a diversity of resource for obtaining positioning data, well organized research support at government level for efficient using is required. Specially, it is very Important that subcommittee for research organized with National GIS Promotion Committee as a leader make counterplan strategy. We have obtained an conclusion that we can make a good decision by establishing Spatial Information Expert Group and selection of essential element of technology.

GIS has recognized as the Social Overhead Capital to improve national competition and to heighterl the productivity of adminstration in 1990's in Korea. As the size and the scope of the NGIS policy have drastically expanded, evaluation has become a critical process. Thus NGIS driving committee has adopted the GIS project evaluation scheme in NGIS law since 2000. But the HGIS evaluation scheme is not sufficient for the comprehensive appraisal on the GIS project in the Second National GIS Master Plan (2001-2005). This research aims to explore an the improved evaluation scheme of NGIS policy.

Geographic Information Systems(GIS) are very useful for spatial analysis and policy in local government administration. Recognizing the value of GIS, Chungnam province authorities put a spur on the introduction and development of it. But they have some difficulty in this process because of technical restraint, expertise shortage and budget limit. This study has surveyed current achievement and conditions for GIS development and presented general framework and subordinate tasks to build up GIS. First of all, there are a few prior conditions to guarantee the success of GIS: First, we should set up reasonable long-term plan and follow systematic procedures according to the plan. Second, it is essential to clarify what initiatively manage to whole business and so we should make up GIS-Board as an institutional center for this job. Third, we must research how to take advantage of already existing NGIS(National Geographic Information System), so that we may eliminate redundancy of investment. We can save a lot of finance and human resources through it. Fourth, we must focus on the importance of accurate mapping by utilizing new technology like GPS(Global Positioning System). Fifth, we should arrange efficient training program to constantly produce excellent human resources for GIS.

본 연구의 목적은 한국에서 시도된 국가지리정보체계(NGIS)구축의 1단계사업에 대한 정책적인 측면에서 해외의 NGIS와 비교하여 2, 3단계 사업의 성공화를 도출하는데 있다. 본 연구의 첫 장에서는 Masser(1999)에 의한 세계 NGIS 추진 10개국의 정책과 핵심분야를 한국의 NGIS와 비교 분석하여 장단점을 제시하였다. 2장에서는 한국의 NGIS정책에 대하여 구체적으로 분석하여 3장에서 한국 NGIS의 핵심5대 분야와 연계한 결과 및 평가의 구체성과 4장에서 한국의 미래 NGIS의 방향을 동시에 제시하였다. 세계적으로 90년대 후반에 시작된 국가지리정보체계의 구축사업 중에서 11개국에 대한 선행정책연구 분석에서 볼 때 한국이 포함된 7개 국가에서 정부주도형의 하향식(Top-down)형식으로 수행하였으며, 3개 국가는 기존 수행체계를 발전시킨 상향식(Bottom-up) 형식이었고 나머지 한 국가는 절충형의 후발주자에 속하여, 한국의 NGIS 1단계사업은 국가주도형의 정책이 주종을 이루는 하향식 정책의 국책사업으로 밝혀졌다. 한국의 1단계 NGIS사업의 정책과 분야는 1995년부터 정부주도 정책에 따라서 2억 $(중앙정부: 64%, 지방정부: 36%)의 예산으로 2000년까지 11개 중앙부처가 참여하고 5개 분과위원회(총괄분과, 지리정보분과, 토지정보분과, 기술개발분과, 표준화분과)에서 10개 사업(지형도전산화사업, 주제도 전산화사업, 지적도전산화사업, 지하시설물도전산화사업, 지하시설물 관리체계개발시범사업, 공공GIS활용체계개발사업, GIS기술개발, GIS전문인력육성, GIS표준화사업, 국가GIS지원연구사업)을 수행한 대규모 국책연구개발사업이었다. 따라서 한국의 미래 NGIS 정책방향은 국가공간정보기반조성을 통한 디지털국토구축으로 국가 Agenda인 'u코리아'를 실현시키고 선진형 대민서비스를 제공하는 것으로 정해질 것이다.

The most important thing for the national GIS development is considered to be the standardization, especially the development of the standard coding scheme for the GIS features and attributes. The comparative study on those of the several international transfer standard is, therefore, very meaningful. In this paper we analyzed the features and attributes coding catalogue for the three different exchange standards; SDTS, DIGEST and SP-57. And also the new coding scheme is proposed as the unified standard frame to be used for all the GIS related application and the digital product.

Currently, satellite images act as essential and important data in water resources, environment, and ecology as well as information of geographic information system. In this paper, we will investigate basic characteristics of satellite images, especially application examples in water resources. In recent years, researches on spatial and temporal characteristics of large-scale regions utilizing the advantages of satellite imagery have been actively conducted for fundamental hydrological components such as evapotranspiration, soil moisture and natural disasters such as drought, flood, and heavy snow. Furthermore, it is possible to analyze temporal and spatial characteristics such as vegetation characteristics, plant production, net primary production, turbidity of water bodies, chlorophyll concentration, and water quality by using various image information utilizing various sensor information of satellites. Korea is planning to launch a satellite for water resources and environment in the near future, so various researches are expected to be activated on this field.
