As the city grows in population and size, land-use plan increasingly becomes a crucial element in developing a city-wide plan. In the process of developing the land use plan, identifying the present conditions and predicting the future conditions are the most important steps. That is, to understand the phenomena of land-use activities as well as to manage uses of the land efficiently require the comprehensive land use information system. This study intends to construct the land use database utilizing the Cadastral Map and Registered Building Data and to examine and suggest the application areas of the database. The database was constructed with those of Busan Metropolitan City. Using the established data, it shows how to use the database to identify the present conditions in Busan.

This study aims to predict the land use demand of Seongnam-city using system dynamics and to simulate the effect of changes in family structure and land use density adjustment policy on land use demand. This study attempted to construct causal loop diagrams and an analysis model. The changes in land use demand over time were predicted through simulation results. As a result of the analysis, as of 2035, an additional supply of 2.08 km² for residential land and 1.36 km² for commercial land is required. Additionally, the current supply area of industrial land can meet the demand. Three policy experiments were conducted by changing the variable values in the basic model. In the first policy experiment, it was found that when the number of household members decreased sharply compared to the basic model, up to 7.99 km² of additional residential land were required. In the second policy experiment, if the apartment floor area ratio was raised from 200% to 300%, it was possible to meet the demand for residential land with the current supply area of Seongnam-city. In the third policy experiment, it was found that even if the average number of floors in the commercial area was raised from four to five and the building-to-land ratio in the commercial area was raised from 80% to 85%, the demand for commercial land exceeded the supply area of the commercial area in Seongnam-city. This study is meaningful in that it proposes a new analytical model for land use demand prediction using system dynamics, and empirically analyzes the model by applying the actual urban planning status and statistics of Seongnam-city.

Rapid growth of the domestic economy caused a lot of the demand of land information. The land information system has to keep the records of the various data about land that includes its owner and usages. Also the system must present adequate results that have been accumulated upon a user's request. Since Korean Government enforces 'Law of National Land Usage and Management', the land in rural area was also tightly regulated as much as that in the urban area. In fact, when people wants to develop their land, then they realize that their land has many restrictions and regulations to use. Sometimes, they find many regulations and restrictions even in a parcel. Thus, many people quite often want to know all the laws, rules, regulations, and restrictions etc., whatever applicable on the land they are interested in. to use. The purpose of this paper is to show a legal service system that precisely presents all the related laws, regulations, and restrictions. for a piece of the land. It summarizes the search results on users' requests. It uses a knowledge-based expert system to figure out the users requests. In this paper, we designed the system architecture of the software, and implemented its prototype. The results on this system show more concise and user friendlier than those of the existing systems.

Geo-spatial information system technology and cartographic modeling techniques were used as a way to Improve the land use planning process. Off-road vehicle(ORV) trails, timber harvest sites, timber haul mads and wildlife ruffed grouse habitats areas should be allocated together in the Wayne National Forest in the United States. Automated spatial cartographic models were developed to resolve the conflicts of the multiple land use allocation. The techniques of descriptive and prescriptive modeling made the multiple land use allocation efficient and effective.

The land informatization methodology is the system development methodology that can be applied to the land information system to construct, manage and use the land information. Therefore, understanding of development methodology of information system and special conditions regarding the land informatization is very important. In order to enhance the understanding of land informatization, we tried various analyses on the previous land information systems developed in KOREA(PBLIS, LMIS, KLIS, KRAS) first. Then, we make a basic system development methodology to fit the land information reference model based on EA(Enterprise Architecture) and components based system. In addition, we investigate various problems or issues that occurred during the process of 30years' experience in KOREA land informatization. At last, we construct the detailed land informatization methodology which was added the method how to tasks to be carried out in each stage to solve those issues. It is the unique land informatization methodology having the most of the distinct characteristics of land information.

The land use/cover information, which is periodically obtained from satellite imagery, can be effectively applied to change detection in rapidly changing urban areas. Also it can be used not only as base maps for spatial database in urban information system but as decision-making data for desired urban planning and development direction. In this study, we carried out both unsupervised and supervised classification on land use from Landsat TM and JERS-1 OPS data, which were collected respectively in 1991 and 1997, covering Kumi City and then detected land use changes.

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.

In early year 2003, the previous Urban Planning Law and National Land Use Management Law were abolished and integrated into the Law regarding National Land Planning and Land Use Management. Accordingly, previous Urban Planning Information System is reformed into National Land Use Information System. This paper intends to develop indexes supporting decision-making process and to construct theme map using digital map that can be utilized for the National Land Use Information System. As a base for the index development, necessary database(DB) was established by utilizing the socio-economic information of towns and villages in Busan and a layer of public facilities. Based on the DB, multivariate analyses were performed to examine and analyze the spatial structure of Busan. It was then expressed and constructed as a theme map. The facility theme map was also constructed based on a layer of public facilities and the shortest distance between towns and villages.

Rapid urbanization and population growth have caused substantial land use land cover (LULC) change in the Kathmandu valley. The lack of temporal and geographical data regarding LULC in the middle mountain region like Kathmandu has been challenging to assess the changes that have occurred. The purpose of this study is to investigate the changes in LULC in Chandragiri Municipality between 1996 and 2017 using geographical information system (GIS) and remote sensing. Using Landsat imageries of 1996 and 2017, this study analyzed the LULC change over 21 years. The images were classified using the Maximum Likelihood classification method and post classified using the change detection technique in GIS. The result shows that severe land cover changes have occurred in the Forest (11.63%), Built-up areas (3.68%), Agriculture (-11.26%), Shrubland (-0.15%), and Bareland (-3.91%) in the region from 1996 to 2017. This paper highlights the use of GIS and remote sensing in understanding the changes in LULC in the south-west part of Kathmandu valley.
