본 연구에서는 토지에 관한 각종 정보 중 현재 2차원에 국한된 지적정보를 지적공부에 등록하고 있으나 토지의 입체적인 활용의 증대 및 이에 따른 입체적 권리의 다양화 등으로 2차원적인 토지정보의 등록방법으로는 효율적인 토지관리 및 소유권 보호에 한계에 이르고 있어 이에 대한 대안으로 3차원 지적정보를 지적공부에 등록할 수 있는 기본방안을 제시하고자 하였다. 이를 통해 국토개발에 대한 정책결정 정보를 효율적으로 제공 할 수 있으며, 국민소득의 증가에 따라 사회간접시설(SOC)분야 및 국민 개개인의 토지이용에 있어 각종 계획과 설계 등의 인프라 조성에 기여하게 될 것이다.

This paper summarizes a preliminary geoid computation for western Mongolia, utilizing the airborne data collected fall 2004, as part of the NGA-DNSC-ALAGaC-MonMap cooperative airborne gravity project. A gravimetric geoid has been computed using the airborne gravity data, SRTM terrain models and GRACE/EGM global fields. The gravimetric geoid has subsequently been fitted to GPS-leveling data across Western Mongolia, as well as for a special Ulaanbaatar city geoid model.

In this study, we get a digital imagery about the objective road and visualize it as three dimensional so called 3D. That is to say that we manage the road trough computerized data or 3D and we can expect to get efficiency of the human resources and economical, timely efficiency which is needed to maintain and manage the road.

GIS technique was applied to the analysis of ambient air quality information. For this study, the air quality information was imported with the geographical information in Capital Area. This study well proves that GIS technique has a great deal of potential to analyze those air quality information, to produce useful information, and to ease the efforts for air quality improvement. Concerning about the data interpolation, the discrepancy caused by applying different method was ignorable, although Kriging method is further developed.
