Safety accidents are increasing, such as changes in groundwater levels due to construction work or natural influences, or ground cave-ins caused by soil runoff from old water supply and sewage pipes. In addition, underground facility management agencies must make efforts to improve the accuracy of underground information through continuous investigation and exploration in accordance with the Special Act on Enhanced Underground Safety Management. Accordingly, in this study, we defined the configuration of equipment and data processing method to collect 3D precise exploration underground facility information and developed 3D underground facility information collection technology to ensure accuracy of underground facilities. As a result of verifying the developed technology, the horizontal accuracy improved by an average of 6cm compared to the existing method, making it possible to acquire 3D underground facility information within the error range of the public survey work regulations.

The purpose of this paper is to search for the construction of UDS(Urban Diagnosis System) which can be effectively applied to selecting or classifying the districts for carving out projects of urban planning based on urban geographic information. In order to promote projects of urban planning, it is essential that selecting or classifying the urban districts should be precisely diagnosed according to the respective blocks. Objective measuring standards are needed for this, and the UDS can be applied to analyzing these standards according to the levels. With these in mind, this paper will consider the present states of Korea and the established states of developed countries. Besides, the interest of this paper is to seek the ways of utilizing GIS most effectively in the urban planning areas and application methods. Also, it will find the ways of applying UDS extensively to selecting or classifying districts far the purpose of carrying out urban planning projects actually in the case areas.

Present address system in korea was originally applied as a lot number system for the purpose of collecting taxes since 1910's, which has been changed irregularly by development of the urban areas. This unreasonable address system has disadvantaged the social welfare and the industrial structure, such as visiting, communication, delivery, sightseeing, marketing, transportation, etc. Therefore the new system, which would be rational and scientific, has been deeply demanded for the better services of spatial information and administrative efficiency of government. Korean government has launched the new address project as part of strengthening measures for national competitiveness since 1996. This paper would discuss the grant scheme of road name and building number in Cheongju city and evaluate the construction process of the new address management system.

Forest accounts for almost 64 percents of total land cover in South Korea. For inventorying, monitoring, and managing such large area of forest, application of remote sensing and geographic information system (RS/GIS) technology is essential. On the basis of spectral characteristics of satellite imagery, forest cover and tree species can be classified, and forest cover map can be prepared. Using three dimensional data of LiDAR(Light Detection and Ranging), tree location and tree height can be measured, and biomass and carbon stocks can be also estimated. In addition, many indices can be extracted using reflection characteristics of land cover. For example, the level of vegetation vitality and forest degradation can be analyzed with VI (vegetation Index) and TGSI (Top Grain Soil Index), respectively. Also, pine wilt disease and o ak w ilt d isease c an b e e arly detected and controled through understanding of change in vegetation indices. RS and GIS take an important role in assessing carbon storage in climate change related projects such as A/R CDM, REDD+ as well. In the field of climate change adaptation, impact and vulnerability can be spatio-temporally assessed for national and local level with the help of spatio-temporal data of GIS. Forest growth, tree mortality, land slide, forest fire can be spatio-temporally estimated using the models in which spatio-temporal data of GIS are added as influence variables.

전라남도 국민참여형 위성영상 블로그 시스템은 2006년도 행정자치부 자치단체정보화지원사업의 일환으로 구축된 것으로서， 사용자가 고해상도 위성영상 위에 직접 자신의 글，사진， 동영상을 올리고，이를 다른 사용자나 시스템과 공유할 수 있도록 구축된 시스템이다. 본 시스템이 궁극적으로 구현하고자 했던 과제는 다음과 같다. (1)지리정보 혹은 기타 정보의 고정성을 탈피하고，(2)지리정보와 멀티미디어 자료의 효율적 통합을 통해 geoUCC를 구축하며，(3)사용자의 참여를 통한 지리정보 제공 방식의 쌍방향성을 구현하여，(4) 사용자를 일방적 자료 활용자에서 자료 생성자로 발전시키고 궁극적으로는 자치단체와 국민 간 새로운 방식의 소통 방식을 생성하는 것이다. 본 시스템 구축의 결과로서 본 시스템에서 일반 국민에게 서비스되는 내용은 다음과 같다. (1) 전라남도 전역의 1m급 고해상도 위성영상의 대국민 서비스，(2)전라남도 전역에 대한 지번 단위까지의 주소 검색 서비스，(3)웹 상에서의 실시간 3차원 GIS 서비스，(4)Web2.0의 철학을 반영한 RSS, Trackback 및 Tag 검색 기능，(5)사용자가 직접 고해상도 위성영상 위에 자신의 글， 사진，동영상，홈페이지 등을 올릴 수 있는 "위성영상 블로그 쓰기 기능"，(6)국내 거의 모든 포털 사이트의 블로그와 홈페이지를 지원하는 시스템 연계(퍼가기) 기능 등이다. 결론적으로 본 시스템의 사용자는 고해상도 위성영상 기반의 지도 위에 자신의 여행기，사진， 동영상을 올림으로써 자신만의 사용자제작콘텐츠(UCC)를 생성할 수 있을 뿐만 아니라， 이를 다른 사용자와 공유， 활용함으로써 실질적인 쌍방향，참여형 지리정보시스템을 이용하게 된 것이다.

The industrial areas including large industrial complexes formed by the process of the growth-oriented industrialization in the past have been attributed to worsening the urban competitiveness of cities due to their infrastructure shortages and aging. Government-led regeneration projects for old industrial complexes have been implemented on a trial basis, but there is a problem with applying a uniform regeneration planning to all the regional industrial complexes with different circumstances and physical environments. In this context, this study diagnosed the social conditions and physical characteristics of the Sasang industrial area in the city of Busan formed by private-led projects in the past and then tried to suggest its regeneration directions. The study area was characterized as its weakening industrial function, infrastructure shortage, and increasing development pressure. Based on these regional characteristics, the regeneration directions were suggested. In the planning phase, pubic-led infrastructure expansion is first needed and urban renewal needs to be applied to some areas designated as priority maintenance areas. In the implementation phase, stepwise projects are required in the medium to long term and it is important to build upon the consensus with private companies through establishing collaborative governance.

SCM(Supply Chain Management)와 로지스틱스에 관한 관심은 최근 몇 년간 많은 사람들의 관심을 끌고 있다. 수많은 혁신기법들을 통해 사업 내 낭비의 요소들을 찾아 비용을 절감하면서 생산성 향상을 통해 기업의 수익을 올리는 식의 방법에 한계를 느끼던 기업은 상대적으로 관심이 적었던 SCM과 물류관리 방면으로 눈을 돌리게 되었다. 특히 많은 기업들은 국가의 인지도와 기업의 이미지와 기술력을 통한 경쟁력이 해외로부터 인식되면서 과거 OEM 방식의 통한 수출에서 벋어나 자가 브랜드로 해외 진출을 꾀하면서 OEM 제품과 자가 제품들에 대한 관리를 위해 해외 거점에 대한 관심이 커지기 시작하였다. 이 논문에서는 지리정보시스템(GIS)을 사용하여 국내 기업의 미주 물류거점 구축 전략을 설명한다. 기업이 물류거점을 결정할 때 어떤 방식을 이용하는지, 의사결정지원시스템으로써 지리정보시스템을 어떻게 사용하고, 어떤 과정을 거쳐 물류거점이 결정되는지를 설명하게 될 것이다.

현재 우리나라는 연안수역에 급증하는 해양시설물 설치사업에 따라 해상교통로를 보존하고 연안수역 해상교통망 수역을 기존에 구축된 지리정보 시스템(GIS)와 연계할 수 있는 방법을 연구중에 있다. 이에 따라 Postgres SQL 기반의 PostGIS를 활용하여 해상교통 밀집분석을 시공간 형태로 구축 하였으며 표출 방법에 따라 최적의 해상교통로를 선정하고자 한다. 표출 방법은 등도수 분할을 활용하여 10개의 등급으로 구분한 후 상위 1개 등급을 우선적으로 선정하였으며, 이를 기반으로 GIS에서 제공하는 다양한 알고리즘을 활용하여 좌표로 구축하고자 하였다. 수많은 격자 데이터와 벡터형태로 저장된 해상교통밀집 분석 결과는 폴리곤 결합, 폴리곤 부분 제거, 폴리곤 스무싱, 폴리곤 단순화를 활용하여 해상교통망을 구축하였다.

The purpose of this study is to suggest the way of effective use of spatial data in Busan metropolitan city. To do so, information systems and spatial data established in each department are analyzed. Spatial data distribution networks scattered around the nation are integrated to the national spatial information clearinghouse and the service is expanded for the public and the private sectors to participate. Information systems supplied by the central government are 22 and information systems operating in the Busan Metropolitan City are 168. In addition, there are also 295 types of the thematic maps in 11 fields related to the environment, road transportation, livestock, and etc. For systems integration and management system, an integrated information management and linkage system is required in the near future. In the next logical step, generation of metadata, experiments for effective utilization of spatial data, and construction of the data center should be necessary.
