GIS technique was applied to identify the regional hydrologic units for groundwater exploitation and recharge analysis in a study area. The technique was very effective to identify the potential areas for groundwater exploitation, and for groundwater management & land use planning. GIS database of environmental resources was complied from a variety of sources and scales as the foundation for analysis, including digitizing and scanning of hardcopy maps. A DEM(Digital Elevation Model) was used to dassify slopes, and identify problematic drainage system. Quantitative analysis of environmental resources helps us to develop the scoring system of GIS model, which evaluates each resource in relation to the others and reflects the relative importance of each resource. ARC4NFO was used to construct digital database, and the cartographic simulation techniques were applied in order to create new maps.

The outputs from the fundamental research program of the Korea Institute of Geoscience and Mineral Resources (KIGAM) were analyzed using the research budget and manpower as input variables. The analysis was performed based on the research outputs of the past 3 years (FY2004 to 2006). More articles and patents came out in applied and development research areas among the geosciences fields. The statistical analysis indicates that each sub-field has different characteristics in research outputs. Research articles, patents, and research budget increase as the manpower increase. But research articles and patents do not always show positive relations to research budget.

This study analyzes emerging earthquake and space use technologies from the latest Korean and Japanese scientific and technological foresights in 2022 and 2019, respectively. Unlike the earthquake prediction and early warning technologies presented in the 2017 study, the emerging earthquake technologies in 2022 in Korea was described as an earthquake/complex disaster information technology and public data platform. Many detailed future technologies were presented in Japan's 2019 survey, which includes largescale earthquake prediction, induced earthquake, national liquefaction risk, wide-scale stress measurement; and monitoring by Internet of Things (IoT) or artificial intelligence (AI) observation & analysis. The latest emerging space use technology in Korea and Japan were presented in more detail as robotic mining technology for water/ice, Helium-3, and rare earth metals, and manned station technology that utilizes local resources on the moon and Mars. The technological realization year forecasting in 2019 was delayed by 4-10 years from the prediction in 2015, which could be greater due to the Corona 19 epidemic, the declaration of carbon neutrality in Korea and Japan in 2020 and the Russo-Ukrainian War in 2022. However, it is required to more active research on earthquake and space technologies linked to information technology.

In this study, we analyzed changes in policies after the Korean New Deal Policy in 2020, metaverse and 6th generation communication technology. In the research and development of geoscience and mineral resources, we emphasized on the connection between smart cities and digital twins by focusing on the linkage of the real world and geo-information. Further, we examined trends in developing digital twins after the Korean New Deal Policy in 2020 that focused on three-dimensional visualization technology, the first stage in implementing digital twins, and real-time monitoring technology of underground information, the second implementing stage. As results of this study, we emphasized on the efforts to provide accurate underground information based on geology, groundwater and geo-environment and to analyze and predict near-real-time levels of available underground information to the industry, local governments and the central governments. Research and development that integrate the fields of geology, environment, and information is required to lead national digital twin policies and smart city policies owing to the acceleration of the digital economy in Korea and globally during the post-Corona era.

Advanced geological surveys and exploration activities were first carried out in Korea in 1884 in accordance with a treaty of friendship and commerce between Great Britain and Korea and a treaty of friendship and commerce between Germany and Korea. The first paper by Gottsche, C. was also published in a German Journal in 1886. Efforts toward independent acquisition of Western geological survey and exploration technology were actively promoted by the Korean Empire in the early 1900s, but were frustrated by the Japanese Empire. Systematic geological surveys and exploration were conducted in Korea by Japanese geologists during the Japanese occupation. A basic geological maps(61sheets), a bulletin on the geological survey of Korea, a bulletin and technical report on deposits in Korea, and a coalfield geological survey report were published during this period. Overall, the intentions under lying the geological surveys and exploration activities by foreigners in Korea prior to the Japanese occupation were questionable. However, the results of these surveys and explorations themselves can be evaluated as positive in terms of academic performance.
