According to the development of information and the possibility of utilizing the most effective were high hopes that a plan is in the area have. Planning process of data collection and analysis and forecasts necessary, because even before the introduction of information, logical reasoning and objectivity of the plan to increase the variety of efforts have been made at an early age. This research try to offer a foundation for the future direction of research. Firstly, land use information systems and related legal issues and sought to review the status. Second, the information system of land use and spatial planning and diagnosing the problem was related to the status of the system. This desirable to propose the development of informatization. Finally, the purpose and the information derived legal system's ability to exert maximum legal system of the maintenance and development of information systems is to propose.

The purpose of this study is to explain the types and causes of errors in zoning data that occur in the topographic map notification procedure, and to prepare a data maintenance plan. In Korea, like the United States, law-based land use regulation is dominant. In other words, according to the land use regulation method in the Act, the government designates zoning for all lots in the country, and landowners check the land use regulations of their land through the Korea Land use Information System. The land use plan confirmation document is important land information that affects the results of administrative dispositions such as land transactions between individuals or permission for development activities. However, there are data errors that occur during the current topographic map notification procedure and data construction process. Therefore, four local governments that can verify data by type were selected in consideration of local government conditions. A number of errors are first, errors in data construction and management in the Korea Land use Information System, and second, errors in lack of expertise that occur while the local government officials maintain data. Third, it was analyzed as an error from the relationship between the serial cadastral map and the zoning DB. Based on the above results, it is hoped that the results of this study will be reflected in the establishment of the KLIP and the reform of the legal system, which is currently underway after the establishment of the 「3rd the Korea Land use Information System Construction Plan」.

The types of national land monitoring data have been changed from the static to the dynamic including the real time and streaming data. So, it would be needed to integrate these national land monitoring data based on the efficient system. In this paper, some cases on the system design for the data distribution were investigated. And also, system design strategies were considered.

The social influence of the elderly population will accelerate in a rapidly aging society. The purpose of this study is to establish a methodology for extracting vulnerable districts of the welfare of the aged through machine learning(ML), artificial neural network(ANN) and geospatial analysis. In order to establish the direction of analysis, this progressed after an interview with volunteers who over 65-year old people, public officer and the manager of the aged welfare facility. The indicators are the geographic distance capacity, elderly welfare enjoyment, officially assessed land price and mobile communication based on old people activities where 500 m vector areal unit within 15 minutes in Yongin-city, Gyeonggi-do. As a result, the prediction accuracy of 83.2% in the support vector machine(SVM) of ML using the RBF kernel algorithm was obtained in simulation. Furthermore, the correlation result(0.63) was derived from ANN using backpropagation algorithm. A geographically weighted regression(GWR) was also performed to analyze spatial autocorrelation within variables. As a result of this analysis, the coefficient of determination was 70.1%, which showed good explanatory power. Moran's I and Getis-Ord Gi coefficients are analyzed to investigate spatially outlier as well as distribution patterns. This study can be used to solve the welfare imbalance of the aged considering the local conditions of the government recently.

The existing 2D cadastre as the core engine of land administration systems met with the difficulty of managing and representing the real 3D world. As a result, a 3D cadastre system has emerged as a solution oriented towards managing, representing and providing 3D spatial information related to physical status, land rights, restrictions and responsibilities. The aim of this study is to establish the foundation of the 3D cadastre information system. With this in mind, this paper aims not only to set up the data range of the 3D cadastre, but also to design a conceptual model based on an LADM (Land Administration Domain Model) through the investigation of legal restrictions and land uses relating to spaces in 3D.

For the exact status of the land such as land cover classification and land use classification, feature classification system has been utilized in several organizations and agencies. However, those classification systems are limited to detection of land change and it's also not suited for the extraction of land changed. In this study, we would proposed a standard feature classification system which presents both in natural and artificial change of land effectively. Based on comparison and analysis of domestic and foreign relevant feature classification system, we proposed a standard feature classification system. In order to validate the applicability of the proposed feature classification system, we evaluated the accuracy with using automatic feature classification based on supervised classification and pre-knowledge hierarchical classification.

Technical regulations in the spatial information domain have been developed by a variety of independent organizations and raised inconsistent and overlapping problems with spatial information standards. Many research projects have been done to solve these problems but due to the difficulty of changing or modifying existing administrative regulations, almost nothing has happened for the harmonization. As a response to the fundamental problem, KATS (Korean Agency for Technology and Standards) recently switched the existing system to "trans- governmental participatory standard operation system" and the administrative change created an independent and consistent standard system in the Ministry of Land, Infrastructure and Transport. The Ministry, as a part of the effort, established its own KSDI(Korean Spatial Data Infrastructure) Standard system. From this context this paper presents a redefinition of technical regulation for the harmonization with spatial information standards, an association model between the standards and regulations, and a maintenance methodology to solve the fore-mentioned problems.

This study aims at defining the concept of a cyber-geospace and proposing how to establish a cyber-geospace fir the entire country in detail. The study defined the cyber-geospace as 'the dynamic second territory of Korea not only to manage the land systematicality and deal with administrative services for the people in aspect of public sector, but also to contain economic activities of corporations and the citizen's everyday lives in aspect of private sector, in a 3D virtual reality made by digitizing various facilities and buildings as well as the entire toterritory including ground, underground and even sea'. In order to establish such a cyber-geospace, the project should be pursued on the national level fir around ten-year period.

The 'Hyper-connected society' in which all objects such as people, device, place are connected via networks and share information being realized. As the information and communication environment changes, spatial information also faces a significant challenge. Korean government is striving to meet the social demand for spatial information that will bring 'Hyper-connectivity' such as autonomous vehicles, drones. Until now, however, it has only partially responded to urgent demand and has not prepared a fundamental countermeasure. In order to effectively and actively respond to the demand for spatial information that is needed in the Hyper-connected society, a strategy that can lead to mid- to long-term fundamental changes is needed. The purpose of this study is to analyze the future demand and application characteristics of spatial information confronted with a big paradigm shift called 'Hyper-connected society', and to search spatial information strategy that can cope with the demand of spatial information in future society.
