National atlas map for provide various information is one part of National territorial Statatics Survey but National atlas map in 2004 year don't have stability and ability. National territorial Statatics Survey in 2005 years have octuple data compare with data in 2004 years but have only one map. One map is going to provide with stability and ability. We don't use DBMS, But We make a similarly struct in file based program. We programmed system of dynamic-linked data with spatial data. To dynamic-linked system, we make search engine to based index struct and make combobox search system. spatial data only have index codes(year, national terrial indicator, area). If spatial data request specfied data, search engine search index code and provide DB data. New system is middle step of using DBMS. We redraw map for display real Korea area (with dokdo). New map is shape and similar Korea map.

Since 2000, the national geotechnical information DB has been constructed by Transport and Maritime Affairs (present Ministry of Land) and recently, it provides more than 210 thousands borehole informations through the geotechnical information DB portal systems. The initial project of underground space information computerization was begun in 2007, focusing on collecting the informations after then additional studies had been conducted to verify the precision and accuracy of collected informations in 2013~2014. In accordance with the recent initiation of the 3D integrated underground space mapping project, it is necessary to construct 3D image of the geotechnical information and evaluate the accuracy and precision of the information. Therefore, in this research, the basic information regarding the precision of the geotechnical DB is provided by kriging method and analysis of RMSE for the systematic 3D construction of geotechnical information. In addition, the elevation data errors of boring information are verified by analysis of elevation data such as boring information data and DEM data.

The national land survey is implemented for the purpose of accomplishing the basic goal called an effective development of national land through close survey on physical/social conditions and periodic/social requirements of national land. However, the situation is that there isn't much difference from other data because the data constructed at the local governments or other ministries are gathered to be processed and provided as national land index which is not a field survey while the situation is that the national land index are changed frequently according to domestic and foreign circumstances and transition so that the applicability is low because there is no data accumulated for a long period of time on the same index. Considering that most government offices and local governments are performing surveys out of their own unique necessity to construct the results followed by such survey as data which includes spatial data as a form of database since the importance of statistics data and map data has become highlighted recently, it is necessary to make a new approach in the aspect of investigating the current situation of national territory on the national level. Accordingly, this study has proposed a new national land survey system to prepare for unification of North and South Korea as well as to provide the decision making data necessary for setting up the policies for effective land development and value conservation of the national land.

건물, 차량, 사회인프라시설과 달리 농작물이란 물리적인 시설이 아닌 농업경제 활동의 결과물로서 최종적으로 판매를 통해 수익을 창출하는 행위에서 재난으로 인하여 지장을 받게 되는 경제적 피해가 고려되어야 한다. 이를 위해 본 연구는 홍수로 인한 농작물 피해를 "생산비 매몰비용"과 "순수익 손해"를 농작물 피해추정의 척도로 하였다. 생산비 매몰비용이란 경작시작부터 피해발생까지 투입된 생산비의 회수불가에 따른 피해이며, 순수익 손해란 피해발생에 따른 기대 순수익 하락에 따른 피해를 의미한다. 다양한 작물 가운데 10종의 대표작물을 선택하고, 각 작물의 표준생산비와 표준순수익을 농업생산 및 수익과 관련한 통계자료로부터 결정하였다. 이로부터 생육경과율과 홍수 발생시기(6~9월)를 고려하여 월별 투입생산비 및 기대순수익을 결정하였다. 대상지역 내 재난에 노출된 작물정보를 정의하는 농작물 인벤토리는 농림축산식품부에서 제작된 스마트 팜 맵(농경지 전자지도)을 활용하였고, 다양한 작물이 혼재된 밭의 경우 농업면적조사 결과를 토대로 결정한 밭작물 재배현황비를 고려하였다. 홍수에 따른 취약성을 설명하는 농작물 손상함수는 영향인자는 침수심, 침수기간이며, 이를 기준으로 한 손상함수는 농림부의 농업재해피해조사요령과 일본 치수경제조사메뉴얼을 참고하여 제시하였다. 본 연구에서 제시한 농작물 피해 추정 방법은 기존 방법인 다차원 홍수피해산정법(MD-FDA)과 비교할 때 대표작물의 현실화, 국내 실정을 고려한 손상함수, 그리고 면적 기반의 원단위를 사용함으로써 실무적으로 명확하고 실용적으로 사용될 것으로 기대된다.

This study research how beginner utilization guild is made of beginner utilization guild for expanding the V-World. We classified the subjects and investigated the purpose of the visit through satisfaction surveys, Depending on the purpose of the visit, we categorize a beginner, intermediate and advanced user of the V-World visit. This paper studies making beginner utilization guild in the majority of visitors of using map-based services. We carried out analyzing function of the V-World, configuration beginner utilization guild, creation contents, making guild. The V-World is a public service that the spatial information of having built of the country provide to Citizens.

The purpose of this study is to compare and analyze the accessibility of living SOC in the 1&2 Phase New-towns. The comparison and analysis were conducted by integrating the given data on living SOC in the 1st and 2nd new towns. As the analysis content, the basic data on living SOC in the 1st and 2nd new towns were compared with the regions outside the new towns, and the contents related to living SOC in the residential satisfaction survey were analyzed. The average access distance by type of living SOC was calculated using the National Statistical Map of the National Geographic Information Institute, and the spatial bias of the distribution by type was derived. In the supply of Life SOC, in addition to the qualitative items of housing, the complex and external environment need to be supplied from the beginning, and as the number of households in the new-towns is matured, sports facilities and hospital facilities, etc., are supplied in response to market demand. There is a need to closely review the layout plan to ensure accessibility to the facility. In particular, in terms of layout in the post-corona era, more in-depth consideration is needed on the accessibility of urban parks and facility accessibility for the elderly and children, who are socially disadvantaged, from a subjective perspective. It is expected to be used as basic data for the 3rd New-towns plan to be built in the future.

Cultural remains distribution maps have been published in 172 volumes of books, and the information about the remains in South Korea is also disclosed via the Internet to those who are interested in conducting archeological examinations or to those who are planning the national land use for various purposes. The purpose of this study is to statistically review the locational characteristics of the sites appearing in cultural sites map, and to determine the locational characteristics of these remains or sites. The location of sites was statistically analyzed based on the point density function of geographic information system of 87,859 sites found in cultural site maps. The results of this study show that the sites found in South Korea are mainly distributed around historical cities and the distributions are closely related to their proximity to rivers. Given that the period of time and type is very important to archeological studies, the results of this study indicate that detailed period of time and type may be necessary for further analysis. This study has highlighted that the research into the spatial analysis and interpretation of cultural heritage sites can contribute to the field of archeological studies.

This study describes the development of coordinate transformation tool for transforming the digital map using newly derived transformation parameters which are determined from the data referred to the local geodetic datum and the geocentric datum (ITRF2000) and the distortion modelling derived from collocation method. We prepared 190 common points and used 107 points to calculate 7 transformation parameters. In order to evaluate an accuracy of coordinate transformation, 83 common points were tested. In this study, we used Molodensky-Badekas model to derive the 7 transformation Parameters. An accuracy of 0.22m was obtained applying 7 Parameters transformation and the distortion modelling together. It shows that the accuracy of coordinate transformation is improved 72% against the result of 7 parameters transformation only. We developed the transformation tool, GDKtrans, which can be transformed the digital map of scales 1/50,000, 1/25,000 and 1/5,000. We also analyzed the digital map of l/5,000 at six urban areas by GPS observations. The result shows less RMSE of about 1.9 m and large disagreement at position and features. Consequently, we suggests that l/5,000 digital map is necessary of whole revision.
