The convergence industry is a combination of technologies or industries of the same type or various types, thereby maintaining and/or expanding the existing values or creating fresh values. As the industry is drawing greater attention over the world, each country is making huge efforts to provide support for it. GeoSpatial Information is a representative convergence industry characterized by being utilized as a basis for other industrial fields by being linked and fused with other industries and technologies. It is well recognized as being a promising industry that will likely lead the national economy in the future. GeoSpatial Information is necessary to analyze the distinctive features and obstacle factors of the convergence industry. Because it will be able to induce a smooth convergence among different industries. In this paper, we has segmented the support elements through a comparative analysis of the legal system related to (Nano Technology, Information and Communication Technology, Culture Technology, etc)the convergence industry. Based on this proposed policy support for GeoSpatial Information Convergence industry. We expect that this study will be used as basic data of the policy established to effectively support for the GeoSpatial Information convergence industry.

The 3-D spatial information systems are effective for systematical urban management and civil administration. They have more visibility than the 2-D spatial information systems with height information. However, the 3-D spatial information systems for local government were developed by central government's master plan of national spatial informatization. It means that the systems are biased toward the 3-D viewing as the visibility like a 3-D display and simulation, without reflected distinct characteristics of the local society. In order to utilize municipalities'3-D spatial information systems efficiently, above all, we have to understand the current status of municipalities'3-D spatial information systems and then have to search the ways applying actively. Therefore, we reviewed the current 3-D spatial information systems and discussed the development directions with central government's national spatial informatization master plans in order to perform properly on the 3-D spatial information system's excellent functions. We analyzed each system characteristics based on the applicability to civil administration which has the potential usage of spatial information. Additionally we suggested the development directions of 3-D spatial information systems for municipalities'through reviewing which civil administrative tasks 3-D spatial information can be applied. The consideration was based on the user demand research of the 3-D spatial information system in Chungcheongnam-do.

In the 21th century, on the level of the limit of national resources, the national land development, the development using the marine resource and the marine space, the international diplomacy and the national security, the island development will be more vitalized. Therefore, considering the various kinds of information becomes diverse and massive quantitatively, it is necessary that we develop an effective system which not only operates the information, but also gives a function of various display using the computer graphic and the multimedia. On this point of view, this study focused on thesuggestion of the application system model which is necessary for an efficient management, analysis and development of our country's island. That is, unlike the previous information system, the IIMS(Island Information Management System) model was developed by the active use of the Geo-Spatial Information System which improves the efficiency of the work by managing the spatial information and the attribute information simultaneously, and objectively induces the decision of the opinion and the policy for the management and the development of the island.

The work establishing effective development and conservation plan and identifying current usage of national territory is an important task of the nation. In spite of the investigation being executed by law up to about 60 different, collecting information, method and time are different between them, so it causes duplication of the budget and policy confusion. And land use listed in the cadastral book officially represents the status of land use, but it is not easy to change according to current use. Therefore collection and information in a consistent manner is necessary to build up. In this study, for the national territory including public waters and underground space, we would like to analyse current land use information collection method and suggest system construction, legal system improvement and information utilization strategies. For the accurate and consistent land management, as a result, 3 dimensional land(include underground, public water and sea etc.) use status inspection and information management is needed. And the new act should be enacted and exclusive organization also be designated.

This study aims to improve understanding of freight movement, crucial for logistics facility investment and policy making. It addresses the limitations of traditional freight truck traffic data, aggregated only at city and county levels, by developing a new methodology. This method uses trip chain data for more detailed, facility-level analysis of freight truck movements. It employs DTG (Digital Tachograph) data to identify individual truck visit locations and creates H3 system-based polygons to represent these visits spatially. The study also involves an algorithm to dynamically determine the optimal spatial resolution of these polygons. Tested nationally, the approach resulted in polygons with 81.26% spatial fit and 14.8% error rate, offering insights into freight characteristics and enabling clustering based on traffic chain characteristics of freight trucks and visited facility types.

Land price is a kind of text to read urban spatial structure. The purpose of this paper is to inquire into the characteristics of Daegu's urban structure and its change in time through exploring spatio-temporal variations of land price with a detailed spatial and temporal resolution. To achieve this, land value surfaces were represented using the officially assessed land price every other year from 1995 to 2011. Through mapping and exploring spatio-temporal patterns and fluctuation rates of land price for this period, changes in urban structure, the effects of local decision makings such as Greenbelt adjustment, housing site development, and gentrification, and the effects of business fluctuations or policies at global or national scales could be caught. In addition, the trends for suburbanization and multi-centric urban form could be examined from the results of a negative exponential model explaining the effect of distance from an urban center on spatial variation of land price. These results demonstrate that urban analysis using land price mirroring spatial decision making at various scales could deepen understanding for internal structure and change of a city and provide useful information for establishing regional and urban development policies and evaluating their effects.

Recently parks and green spaces contribute not only as a place of leisure but also for environmental welfare, social education, new jobs and $CO_2$ Emissions Reduction. Parks and green spaces are understood as urban infrastructures like roads and rivers. They are also included in social infrastructures like education, culture, and welfare facilities. These changes are applied to policies for parks and green spaces, many governments and local authorities make investments on them. The modification of policies for parks and green spaces in England is a good example about this trend From this view point, this study now deals with the changing process of policies, results, and evaluation. Some implications have been deducted. The first is the inducement in participation in policies and implementation of practices through policy papers. They are more practical than written laws which are composed of abstract sentences and generalizations. Secondly, the status of parks and green spaces is highly raised with the establishment of CABE Space and so on. This organization controls many different policies and programs related to parks and green spaces. Third is the funding for the improvement of parks and green spaces. Fourth, are the short-term measures, such as funding and management, and the long-term measures such as pursuing building of partnership and training. Fifth, the government strives to establish its partnership with the local authorities and communities through a spectrum of support in terms of information, monitoring, and developing good practices among networks. Finally, parks and green spaces are being addressed from multiple directions through the participation of numerous agents like voluntary groups, development companies, communities and so on. Recently, in Korea, the influences of the Sunset Law for Park Site, Landscape Architecture Law, Urban Forest Law, and other related ordinances have encouraged the review on the policies on parks and green spaces needed. However, there are not many studies about them. Owing to these reasons, the cases of England will he helpful.

The ubiquitous city construction act worked as an institutional basis for the U-City projects which were actively driven in the new urban areas until 2010. However, the country's urban policies which were recently changed focusing on revitalization of the existing towns and urban regeneration led to the increased demand for revision of the u-City law with a strong character of procedural law mainly for the new urban areas. Therefore, this study, taking into account the changes of the country's urban policies and the conditions related to u-City, established the direction of revision on the u-City law as the diversification of the u-City projects, reinforcement of u-City management operation and the supports for the u-City projects, and presented the consequent action plans. This study aims to review the problems with the current u-City law and the improvement plan from the practical point of view for reflecting the country's urban policy flow and demand. It is expected that the result of this study will be able to be utilized as a basic material for supporting the continuous development and expansion of u-City by law and system.

물정보 중 가뭄 정보가 상대적으로 부족한 원인은 무엇을 가뭄으로 볼 것인지 정의하기 어렵기 때문이다. 특히 우리나라와 같이 댐 및 저수지, 광역상수도 등 수자원시스템 네트워크를 기반으로 물공급이 이루어지는 경우, 개별 요소만을 고려한 기존 가뭄모니터링 및 전망은 현실적이지 못하며, 가뭄 위험도 관리 측면에서도 부족한 부분이 있다. 가뭄 현상의 경우 기상학적 영향인 강수의 부족이 가장 큰 요소로 기여하지만 실질적으로 국민에 필요한 양보다 적은 양의 물이 공급될 때 국민들은 가뭄을 체감한다. 이러한 점을 보완하기 위하여 지역별로 사용하는 수원 및 물수급 시설 등을 세분화하고, 실적기반 분석을 통해 분석대상 지역의 가뭄을 정확히 판단하기 위한 합리적인 물수급 분석 모형 개발이 필요하다. 즉, 공간분석단위를 표준유역 단위 이하의 취방류 시설물을 기준으로 구성하고, 이들 시설물의 운영정보와 수문기상 빅데이터를 연계한 물순환 모형을 구현함으로써 댐, 저수지, 하천 등 다양한 수원을 가지는 유역 내 가용 수자원량을 준실시간 개념으로 평가하는 시스템의 개발이 필요하다. 본 연구에서는 하천을 중심으로 물수급 관련 수요·공급 시설의 위치를 절점으로 부여하고 연결하는 물수급 네트워크 알고리즘을 통해 빅데이터 기반 물수급 분석 모형을 개발하였다. 주요 모니터링 지점 및 모든 이수 시설의 위치를 유역분석 기법을 통하여 점(point), 선(line), 면(shape)으로 구성된 지형공간정보의 위상(topology) 관계를 설정하여 물수급 분석의 계산순서를 선정하고, 시계열 DB를 입력하여 지점별 물수급 분석 결과를 도출하였다. 권역별 주요 수위-유량관측소 1:1 Nash 계수를 검증한 결과 저유량에서 0.8 이상의 높은 재현 성능을 보이는 것으로 나타났다. 이에 따라 본 연구에서 개발된 물수급 분석 모형은 향후 물관련 이슈 지역의 용수공급능력 평가 및 수자원장기종합계획 등 다양한 수자원 정책평가에 활용될 것으로 기대된다.
