Recently, in a field of cadastre, a computerization of cadastral map is in progress with great growth of GIS field. Also, the needs for the integration of land and building information are widely increasing for integral-management and its application of various land related information. In this study, it is constructed a 3D information cadastral map model that can make the integral management of land, building, connecting land recorders, building management ledgers, building titles, building pictures, and related attribute information.

건축, 토목기술의 발달과 토지의 효율적 이용 요구 증가로 인해 인간의 생활공간은 지표에서 지상, 지하로 확대되었다. 기존의 2차원 지적 시스템으로는 관리의 한계성이 있기에 이런 현실을 효과적으로 반영할 수 있는 3차원 지적 시스템의 필요성이 제기되었다. 이 연구에서는 3차원 지적 시스템의 구성요소와 개념적 데이터 모델들을 소개하고 현 상황을 반영한 효율적인 개념적 데이터 모델을 제시한다.

This study developed a mobile application system for serving cadastral information needed to propel diverse cadastral works including cadastral resurvey efficiently. First, BlackPoint-Xr was selected as a spatial client engine to embody the cadastral information system based on mobile device including smart phone and tablet PC. The mobile cadastral information system contains functions such as finding location with GPS based on spatial information such as aerial photo, cadastral map, administrative map, and digital map, parcel search with address and lot number, finding land register including land address, the classification of land, and land price. Especially, this study developed functions which can analyze the measurement of distance, area, slope and cross-section elevation of land to apply construction work and land maintenance project. This system can support efficiently cadastral work and construction project by serving diverse cadastral information to users in field and can be also applied to the field of digital cadastral information.

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.

This study focuses on evaluating that South Korea has the territorial right of Manzhouguo with disconfirming that China had the territorial right of Manzhouguo after the Second World War. This study also suggests the necessity of territorial cultures with establishing the theory of cultural territories and territorial cultures. The four main territorial cultures of Manzhouguo that are the burial culture, the place name cultural, the cadastral, and the folk culture were analyzed with Classifying territorial cultures. The results shows that territorial cultures of Manzhouguo is the same with territorial cultures of South Korea. Thus, This study suggests that territorial cultures of Manzhouguo should be vest to South Korea and not to China, because of the theory of cultural territories, which is that territorials can be defined with cultures and territorial cultures, which cultures can be defined with territorials.

The field of cadastre and land administration is susceptible to changes in technological development and requires a robust system to respond. In Mongolia, there is a need for a future-oriented and robust cadastral system to cope with these changes. Therefore, this study chose the Land Administration Domain Model (LADM) which is created by the International Organization for Standardization(ISO), and analyzed for its application to the cadastral system of Mongolia. For the application of LADM for Mongolia, we analyzed four packages and each class of LADM based on characteristics of Mongolia's cadastral system and cases of countries applying LADM. As a result of this analysis, we have completed LADM national profiling in Mongolia and proposed the possibility of applying LADM. In the future, based on this research, application of LADM will play an important role in Mongolian cadastral system where the current data model standardization is not established and is useful as a reference model.

International Standard Organization for Standardization Technical Committee 211(ISO TC 211) aims to define and develop standards for information concerning objects or phenomena that are directly or indirectly associated with a location relative to the Earth. ISO TC 211 is working with LADM as a new project based on the existing research which is CCDM. Land Administration Domain Model is, as a international standard model, mainly connected to administration law, spatial surveying components related to cadastre all over the world and provides an extensive basis for an efficient and effective land administration system to avoid reinvention and re-implemention. Further, LADM helps to communicate land information both within a country and between different countries. This study introduces what LADM is and researches how to adopt administration law, spatial surveying components of LADM for Korea Land Information System(KLIS).

In this study, sample sites are chosen where digitalized cadastral maps are available, and boundaries of forestry, farming lands, and residence are clearly distinguishable. Digital orthophotos, produced from aerial photographs, are overlaid with digitalized cadastral maps to grope for applications of digital orthophoto in cadastre. The conclusions and applicable fields of this study are as follows. The first. digital orthophoto is applicable to solve problems such as discordance and duplication of boundary produced in the process of digitizing cadastral maps. The second, using digital orthophoto, it is possible to extract regions where a trouble of ownership would exist and so the necessity of cadastral resurveying can be brought. The third, by overlaying digital orthophoto and cadastral map, it can be used effectively for the present situation maintenance of buildings. The fourth, because it is possible to examine current land use of each lot, digital orthophoto may contribute to decide the validity of land category on cadastral map.

The paper reviews the adoption of ISO 19152, Land Administration Domain Model (LADM) for the enhancement of the current Mongolian cadastral system. It can be said that the current cadastral system is developed for the pure purpose of land registration. There is a need for a comprehensive data model for not only this reason but also reflecting the current problems in the Mongolian cadastral system. The LADM was published by the International Organization for Standardization later in 2012 as an International Standard for modeling cadastral and land administration information for the purpose of providing a common vocabulary(ontology) and efficient system development. This study examined possibilities of adopting the LADM to the cadastral system for Mongolia focused on Land Manager system. Data model of the Land Manager was examined against the corresponding LADM classes and as a result, gaps between each data model have been drawn. Lastly we proposed the LADM-based new data model for Mongolian cadastral system ensuring that the current problems be reflected.

In this study, we analyzed the soil salinity of Saemangeum agricultural land using GIS spatial interpolation method. Dominant soils series of experimental sites were Munpo (coarseloamy, mixed, non-acid, mesic, typically fluvaquents), which was based on the fluvio-marine deposit. Soil samples were periodically collected at 0~20cm and 20~40cm layer from each site. First, the distribution characteristics of EC, ESP, and SAR according to spatial interpolation were analyzed using 142 sample points. Through the error analysis of 143 validation points, the IDW method for EC and SAR, and the Kriging interpolation method for ESP were selected as the optimal interpolation method. Using the optimal interpolation method, the characteristics of EC, ESP, and SAR were analyzed for the change of soil salinity from 2014 to 2016. As a result, EC, ESP and SAR were decreased by 0.26mg/L, 5.97mg/L and 0.73mg/L respectively due to the dilution effect caused by rainfall.
