To provide effective management policy of geo-heritages, concept of Korean geo-heritage has been organized based on geo-diversity, geo-conservation, geo-tourism, and earth-heritage. In addition, current status of geo-heritage in Korea has been grasped, and categorized. In case GPS (Global Positioning System) coordinates exist, spatial information was constructed as GIS (Geographic Information System). Geo-heritages were classified into a total of six categories of natural monument, scenic site, coastal sand-dune, natural cave, world nature heritage, and other types of geo-heritage. By mapping 991 geo-heritages scattered nationwide using geographical information, all statuses can now be readily identified and enable the analysis of the distribution tendencies and correlation with topography. This study was aimed at searching the political connection based on quantitatively organized and analyzed geo-heritages, which have not been mapped thus far. In addition, this study organized data that have existed only in literature, and presented example verification. Moreover, these can be used as guidelines for the future search, discovery, registration and management of geo-heritage. If additional geo-heritages are discovered in field studies or with satellite images, then more correlations may be identified and help facilitate the research on geo-heritages management plans.

Recently, spatial integration for mineral exploration is regarded as an important task of various geological applications of GIS. Therefore, theoretical bases of data representation and reasoning concerned with Dempster-Shafer theory and Fuzzy theory were systematically as the data-driven integration methodologies for raster-based geoinformation; they are distinguished from target-driven methodology based on statistical background. According to previous actual applications of these methods to mineral exploration, they have been proven to provide useful information related to hidden target mineral deposits, and it is thought that some suggestions in this study are helpful to further real applications including representation, reasoning, and interpretation stages in order to obtain a decision-supporting layer.

The aim of the study is to select and verify for development of groundwater resources using Geographic Information System(GIS). The water balance, land cover, forest, soil, elevation, slope, hydrogeology and lineament were analyzed. Using GIS, relationship between the data and groundwater yield data was analyzed and the groundwater resources potential map was made for selecting suitable area for groundwater development. Then groundwater resource potential map was verified using groundwater yield data. The verified result showed the good agreement between the potential map and groundwater yield data. The potential map can be used for groundwater management which is related to groundwater development.

한국자원연구소는 1998년에 영국지질조사소가 설계, 제작한 FLARE+ 지자기연속관측시스템 한 대를 한국자원연구소 내에 설치하고, 연속적인 관측을 수행하고 있으며, 이 관측소를 IAGA 에 등록하고 국제지자기관측소식별부호 DZN을 받았다. 이 시스템은 5초 간격으로 지자기장의 3 성분을, 1분 간격으로 총자기장을 측정하여, 1분 평균자료를 생산하고 있다. 지자기 관측자료? 활용 분야들 중 하나인 지역적 지자기 변동지수(local K index)를 게산하였다. 이를 위해서는 1999년 3월 2일부터 18일까지 17일 동안 관측자료를 기초자료로 하였고, 대전지역의 최대변동폭을 300 nT로 가정하였다. 그결과, 지자기의 최대 변동 지수 폭을 0~9 까지로 할 때, 사용된 자료로 계산한 지역적 지자기 변동지수는 1~6사이에 분포하였고, 최대빈도의 변동지수 3이었다. 한편, IAGA가 계산한 같은 기간의 전지구적 지자기 변동지수(planetary k index)는 0~6사이에 부포하였으며, 최도빈도의 변동지수는 역시 3이었다. 위 기간 동안의 대전의 지역적 변동지수 수열과 전지구적 지자기 변동지수 (planetary K index) 수열 사이의 상관계수(cross correlation coefficient coefficient)는 0.66563이었다. 이것은 지역적 변동지수가 전지구적 변동지수 같은 방향으로 변화하고 있음을 뜻하며, 지역적 변동지수를 해당 지역의 지자기 변동을 대표하는 값으로 쓸수 있음을 뜻한다.
