The use of private property occurs fatally to achieve public work such as road construction and appropriate compensation for land expropriation must be performed to use private property such as land. Since compensation of land expropriation is complicated and compensation target is various, electronic processing system development for land compensation processing business is required. The land compensation system for Regional Construction Management Office applied geographic information system (GIS) technology to land drawing that becomes basis of compensation business when constructing roads. It can perform the establishment of compensation planning, the understanding of the present state of compensation and the management of compensation business by connecting with land position information on drawings. We also implemented our system so that it can effectively accomplish various kinds of works such as compensation by agreement, expropriation, decision and deposit etc. Development of the land compensation system that can reduce time for processing civil affair administration and decrease costs efficiently to handle land compensation business

The aim of this study is propriety review for underground facility surveying on development area of land for housing and efficient management. Because of integration information administration system construction of the nation and development of information technology, construction of Urban information system(UIS) to manage systematically city space is increasingly necessary We manage systematically attribute information for each lot in the development area of land lot housing that it Is connected with NGIS in order to drive gradual computerization of underground facilities and arrange the base of facility management. Review arrangement methods on development area of land for housing makes it to check safety accident of urban and to leading base of urban information. Thus, this study draw the most suitable way through analysis of driving methods and expectation effect from above facts.

Land contamination has emerged as a major environmental and land management issue over the last decade. Although the importance of contaminated land management was continuously increased and many developed countries tried to make advanced contaminated land register system, current Korea soil regulations and policies have not been considered yet. This study analyzed existing or developing contaminated land register system from various countries to suggest implications of environmental decision support. Through this study, the introduction of contaminated land management system as creating a new system in Korea needs to considerable review to the following in order to achieve the objective through a effective adoption and operation (1) we need to establish contaminated land register system by providing a proper legal basis before the imposition of data collection, investigation, and management, (2) sufficient examination is required to identify scope of information disclosure and criteria, contents, and subjects of items from contaminated land register system.

By the rapid development of computer technology and the more efficient use of land-related information, Land-related Information System has been developed by the central and local government respectively. The problems of the storage, maintenance and exchange of land-related data will be anticipated. The purpose of this study is to meet the demands of governments and prevent the duplicate investment for the information system. The data sharing and standardization should be achieved for the more efficient land management. The theme of UN's sustainable land management and the future vision of cadastre according to Cadastre 2014 are thoroughly reviewed. The advanced foreign cases of LIS development are studied, too. Linkage among land-related data, the improvement of organizational institution and the training for GIS specialists are suggested as the strategies for the more efficient land-related information system development.

The use of remotely sensed data and geographic information system (GIS) to develop conservation-oriented watershed management strategies on Imha Dam, Korea, is presented. The change of land use for study area was analyzed using multi-temporal Landsat imagery. A soil loss model was executed within a GIS environment to evaluate watershed management strategies in terms of soil loss. In general, remotely sensed data provide efficient means of generating the input data required for the soil loss model. Also, GIS allowed for easy assessment of the relative erosion hazard over the watershed under the different land use change options. The soil loss model predicted substantial declines in soil loss under conservation-oriented land management compared to current land management for Imha Dam. The results of this study indicate that soil loss potential (5,782,829 ton/yr) on Imha Dam in 2003 is approximately 1.27 times higher than that (4,557,151 ton/yr) in 1989. This study represents the first attempt in the application of GIS technology to watershed conservation planning for Imha Dam. The procedures developed will contribute to the evolution of a decision support system to guide the land planning and dam management in Imha Dam.

The goal of this research is to suggest the desirable directions of the land policies implement system based on analysis of existing those of Korea with the paradigm shift of land policies. We classify the land policies into land ownership, land use, land development and land management ones, and then analyze their implement system characteristics. The results are follows : firstly, the land policies implement systems have been set to large scale and rapid development. Secondly, although the systems have been specialized by their areas, the comprehensive manage systems for the harmony between development and conservation are lacking. Thirdly, the parts of the central government powers related to land use has been hand covered to local governments. And the participations of residences private companies have enlarged in the land development. Fourthly, the purposes of the information management on land use have been changed from tax collection into planned land use, but the information management has not met the need of planned land use. This study shows that firstly, the implement system focusing on large development projects might be no longer effective because of high possibility of the property prices stabilization, so moderately small ones must be found. Secondly, the system cope with the climate change and to realize the efficient utility of land is needed. Thirdly, it is necessary to take the actual measures to participate a variety of subjects. Fourthly, the system modification of the land information manage system as land policies infra is also needed to establish integral land policies.

This study compared and analyzed the construction of a land use change matrix for the Intergovernmental Panel on Climate Change's (IPCC) land use, land use change, and forestry area (LULUCF). We used National Forest Inventory (NFI) permanent sample plots (with a sample intensity of 4 km) and permanent sample plots with 500 m sampling intensity. The land use change matrix was formed using the point sampling method, Level-2 Land Cover Maps, and forest aerial photographs (3rd and 4th series). The land use change matrix using the land cover map indicated that the annual change in area was the highest for forests and cropland; the cropland area decreased over time. We evaluated the uncertainty of the land use change matrix. Our results indicated that the forest land use, which had the most sampling, had the lowest uncertainty, while the grassland and wetlands had the highest uncertainty and the least sampling. The uncertainty was higher for the 4 km sampling intensity than for the 500 m sampling intensity, which indicates the importance of selecting the appropriate sample size when constructing a national land use change matrix.

The compensation data for submerged land have been filed in the form of document or managed with spread sheet like Excell up to now. In the case of dam or highway construction, huge compensation data for the submerged or included land have been managed inefficiently by the administrative manpower. Moreover, where and how to keep the enormous data becomes big problems. In response to the requirements, an submerged land compensation management system based on the location and property information of parcels was developed. The compensation management system has many functions including site searching for compensation, compensation money computing, and compensation data managing. It is expected that the submerged land compensation management system creates various information effects.
