건교부와 지자체에서 공시하는 토지의 개별공시지가는 국민의 재산권 행사에 매우 중요한 자료로서 정확한 산정이 요구된다. 정부에서는 한국토지정보시스템(KLIS : Korea Land Information System)등을 활용하여 개별토지의 특성을 관리하고 공시지가관련 민원업무를 수행하고 있다. 한국토지정보시스템은 개별공시지가 산정의 효율성 향상과 자동화에 기여하고 있으나 여전히 개별공시지가 산정을 위한 토지특성 조사는 공부조사 및 현장조사에 의존하고 있어 토지특성 조사방법에 대한 개선이 요구되고 있다. 이 연구에서는 개별공시지가 산정의 기초자료가 되는 토지특성 중 한국토지정보시스템에서 획득할 수 없는 토지 특성치를 공간정보와 GIS 공간분석을 통해 획득할 수 있는 방법을 제시하며, 조사요원에 의해 조사된 실제 토지특성과 비교하여 GIS 공간분석의 효용성을 검증함으로써 조사 업무의 효율성 향상과 과학화에 기여하고자 하였다.

The primary purposes of this study are to identify the characteristics of land development in urban area through GIS and remote sensing techniques and to provide useful implications for urban spatial policy. To perform these tasks, Daegu metropolitan city and its vicinities were selected as a study area, and remote sensing data and attributed data were collected, organized and analyzed. This study focuses on the following three steps. First, it identifies the characteristics of land development in urban areas by utilizing multi-temporal satellite image data (Landsat TM, 1980, 1985, 1990, 1995, 2000 and 2005). Second, it tries to find an answer on a critical question concerning land use conversion, i.e., which land use leads expansion of urban area? Third, it derives implications for urban spatial policies based on these findings. The characteristics of the urban extents tell us that the main land use converted into urban use from non-urban uses is green areas. The public sector, central and local governments, leads the land use conversions of suburban lands as exclusive legal body to issue permission of land use change. Based on these findings, this study concludes that the more systematic and technically advanced management tools should be utilized for more effective spatial management for urban growth.

This study aims to find out the genetic characteristics of gridded subdivision area which has its origin from ancient local administrative city-Sangju, Jeonju, Namwon, Kwangju, Chungju. The spatial structure, based on the inter-relationship among gridded subdivision area, city wall, and topographic condition, and the morphological characteristics of gridded subdivision area are analyzed. The points of analysis on morphological characteristics of gridded subdivision area consist of the size of unit block, the organization system of unit block, the orientation of subdivision line. As a result of the analysis, three main characteristics are found. Firstly there can be found no same land subdivision rule among study areas. Secondly, the morphological features of study area were the products of cumulative process of different subdivision areas which were developed in different periods. Thirdly, the original regular gridded land subdivision seems to have been carried out in the object of a farm-land cultivation around 7th century. And there was a change of land-use from farm land to urban land-use during the later 7th century and 8th century.

This study was conducted to predict future land-cover changes under climate change scenarios and to cluster analysis of regional land-cover characteristics. To simulate the future land-cover according to climate change scenarios - A1B, A2, and B1 of the Special Report on Emissions Scenarios (SRES), Dyna-CLUE (Conversion of Land Use Change and its Effects) was applied for modeling of competition among land-use types in relation with socioeconomic and biophysical driving factors. Gyeonggi-do were selected as study areas. The simulation results from 2010 to 2040 suggested future land-cover changes under the scenario conditions. All scenarios resulted in a gradual decrease in paddy area, while upland area continuously increased. A1B scenario showed the highest increase in built-up area, but all scenarios showed only slight changes in forest area. As a result of cluster analysis with the land-cover component scores, 31 si/gun in Gyeonggi-do were classified into three clusters. This approach is expected to be useful for evaluating and simulating land-use changes in relation to development constraints and scenarios. The results could be used as fundamental basis for providing policy direction by considering regional land-cover characteristics.

The purpose of this study was to suggest basic natural park planning guidelines which have to be considered before conservation plan. For this purpose, land potentiality was analyzed in the regional context. Natural parks in Tokyo Province were chosen as study areas because park systems in Japan and Korea are similar and lots of information are available in Japan. Land capabilities of study areas were analyzed, then the results were utilized to discuss how the natural parks. Land potentiality was analyzed by the degree of location quotient of land use allowance in homogeneous bio-physical land units, then comprehensive potentiality of bio-physical land units was revealed from existing and historical land use allowance. These 2 allowances, also, were utilized to find the limit of land use intensity, and the results were used for qualitative identification of the land potentiality and the land capability. As a results, the land use allowance and characteristics of 6 groups were identified as shown in Table 3 and Figure 6. Qualitative analysis of land potentiality in this study enabled to disscus the conservation and/or preservation of natural parks, based upon elements of land, and the guidelines of natural park conservation policy were suggested from the characteristics of land potentiality and regional relationship. This discussed land potentiality, and existing natural resources which were stressed from conservational view point need to be combined for comprhensive understanding of land resources.

Land reform was performed in most under-developed countries after liberation from colonialism. In Griffin's thesis, the objectives of the land reform were classified in to three categories based on their ideology. Under capitalist ideology, emphasis was placed on the property ownership, so there has been existed large farms and various tenancy systems. But in this study the characteristics of capitalism was defined as deligence and thrift, and parity exchange. Land reform, tenants must have their own land, is the basic solution to support these characteristics.

Two main sources of data, meteorological data and land surface characteristics, are essential to effectively run a distributed rainfall-runoff model. The specification and averaging of the land surface characteristics in a suitable way is crucial to obtaining accurate runoff output. Recent advances in remote sensing techniques are often being used to derive better representations of these land surface characteristics. Due to the mismatch in scale between digital land cover maps and numerical grid sizes, issues related to upscaling or downscaling occur regularly. A specific method is typically selected to average and represent the land surface characteristics. This paper examines the amount of flooding by applying the FLO-2D routing model, where vegetation heterogeneity is manipulated using the Manning's roughness coefficient. Three different upscaling methods, arithmetic, dominant, and aggregation, were tested. To investigate further, the rainfall-runoff model with FLO-2D was facilitated in Yongdam catchment and heavy rainfall events during wet season were selected. The results show aggregation method provides better results, in terms of the amount of peak flow and the relative time taken to achieve it. These rwsults suggest that the aggregation method, which is a reasonably realistic description of area-averaged vegetation nature and characteristics, is more likely to occur in reality.

As a result of establishing the regional self-government system, regional residents came to take more interest in their land ownership rights and relevant areas. The administrative bodies in South Korea are trying their best to meet the complicated and diversified demands of the residents regarding land and construction administration. However, governmental agencies are having difficulties identifying land characteristics on the field as part of standard lands change every year. Also, the vague boundaries of agricultural and mountainous land areas are causing surveyors problems in spotting the right areas. Thus, this study intends to provide information and guidance on an accurate land price calculation system in connection between the land information system and PDA technology for distribution of accurate information regarding lands and their management.

Land use types within a watershed closely are related with the water quality characteristics of receiving water bodies. Despite of a numerous studies suggesting a strong relationship between water quality and land use, there have been increasing concerns about the geographical variation and a lack of spatial integration in that relationship, which are essential to implementing these findings into land use planning and management. In the meantime, edges mediate the material flux between adjacent systems. This mediating effect of edges is strongly related to the complexity of their shapes. Land use activities within a watershed have a direct impact on the water quality of adjacent aquatic systems, and hydrological processes carry residuals from watershed into adjacent aquatic ecosystems through the edges. Therefore, the geometry of reservoirs theoretically affects the relationship between land uses in the watershed and the quality of receiving bodies of water. In this light, this study integrates the geo-spatial dimensions of land uses in the watershed using GIS and landscape indices in order to explore the relationship between land uses and water quality. Water quality characteristics, land uses and geometry of 133 randomly sampled reservoirs were correlated, based on buffer zones and types of reservoirs. The findings showed that land uses, particularly urban land uses, significantly affect water quality characteristics including BOD, COD, TN and TP, and geometry of reservoirs reduces the concentration of pollutant and nutrients in reservoirs. One of results indicates that the relationship between land use and water quality and effects of spatial dimension may vary with types of reservoirs and pollutants. These results suggest that lakeshore areas are important, particularly for TN reduction and call for a caution to land use activities nearby shoreline areas for sustaining better water quality.
