GIS Tools is able to not only store the integrated information between attribute data and spatial data, but also analyze them. Most of GIS Tools support current information of land. However, lawsuit of right of possession as well as statistic of past data for land policy may need historical information. Therefore, in the paper, we designed the spatiotemporal operators what can handle the historical information. and implemented them. The spatiotemporal operators are used in the history management system of Cadastre and Cadastral map based on GIS. The historical information is generated in spatial operation of spatiotemporal operators and then the implemented operators provide a function to store the historical information, and handle them.

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.

The purpose of this study is to evaluate the urban land used by the Urban Land Use Information System (ULIS) which can supply the micro-level land usc information for the understanding of micro-level urban spatial structure and district-level planning and managements(such as urban design, redevelopment planning and district-level transportation planning, etc.). The study evaluates the current situation of urban land use database and suggests the prototype of urban land use database using GIS. The planning and management of post-modern city which has characterized by diversity and the mixture of land use, need more detail and quantitative information about land use. Recent redevelopment and reconstruction of existing physical condition are increasing the density of activity. It raises urban problems such as the shortage of infrastructure and traffic congestion, etc. In this process we need to construct information system which monitors current land use situation.

위성영상은 항공사진과 더불어 지표면의 변화를 신속하고 주기적으로 관찰할 수 있다는 장점을 가지고 있다. 이러한 장점뿐만 아니라 위성영상에 포함된 분광정보는 시간에 따른 지표면의 변화를 면밀하게 관찰이 가능하다. 이러한 장점들을 이용하여 현재 도시의 중추적인 교통수단으로서의 역할을 하고 있는 지하철 구간주변을 대상으로 시간에 따른 공간변화를 알아보았다. 지하철 건설전후의 구간을 대상으로 Landsat TM영상을 이용하여 토지이용변화 정도를, SPOT Panchromatic 영상을 이용하여 주거 및 상업지구의 변화정도를 위성영상을 통해 살펴보았다. 또한 부산에서 발간한 토지건축물 대장, 교통유발금부과대장을 통해 영상에서 나타난 건물들이 어떤 용도의 건물인지를 파악하고 부산교통공사에서 발간한 일반현황자료를 통하여 지하철이용의 현황과 이용행태를 주변 공간변화와 더불어 분석해보았다.

The collapses of retaining walls or embankments, the soil erosion and landslides around urban areas are occurring by heavy rainfalls because of the recent climate change. This study conducts the soil erosion modeling, while applying the spatial information such as soil maps, DEM and landcover maps to the RUSLE model. Especially this study draws up the soil erosion grade map and the unit soil erosion grade map by parcels through coupling the soil erosion with the cadastral map, and by that can calculate the number of parcels by soil erosion grades. Also the sediment disaster information system based on the mobile GIS is developed to identify the soil erosion grades of site in the urban plannings and the construction fields. The sediment disaster information system can identify the present conditions of the registers of lands, buildings and roads, and confirm the RUSLE factors, the soil erosion, the sediment disaster grades by parcels. Also it is anticipated that this system can support the sediment disaster work of site effectively through searching the locations and attributes of the specific parcels by Administrative Dong and the soil erosion grades.

The current cadastral business is being operated by conversion to a digital cadastral management system through computerized registers (land register and forest land register) and maps (cadastral map and forest cadastral map). Digital surveying methods, such as GPS surveying and electronic plane table surveying, are also used for cadastral surveying. At present, fees for cadastral surveying are calculated based on a standard pursuant to the Construction Standard Production Unit System and an announcement by the Ministry of Land, Infrastructure, and Transportation. In many cases, however, the cadastral surveying fee system announced at present fail to apply the digitalized environment depending on the item. This study sought to analyze the cadastral surveying fee system that requires improvement in the rapidly changing digital cadastral management environment, and to prepare a basis to establish a cadastral surveying fee system suitable to the digital environment by suggesting an improvement method for such system. As a result of the study, the following suggestions were made: a method of changing to terms suitable to the digital environment based on the current status analysis; preparation of a new estimation system regarding new estimation items; and re-survey of an estimation system of cadastral confirmation survey and preparation of an estimation system.

장박사께서 농업통계의 현황과 장래에 대하여 상당히 여러 분야에 걸쳐 상세한 문제점을 지적해 주셨다고 봅니다. 특히 근본적으로 필요한 지적도와 토지대장의 미흡함이나 정도높은 지역통계의 발전및 인원 및 장비의 부족 등에서 오는 비표본오차의 문제점 등 우리나라 농업통계가 풀지 못한 점을 지적하셨고 반면 짧은 역사의 농업통계의 발전도 함께 소개해 주시기도 하였읍니다. 사실 저 자신 이렇다할 수준에 있지 못하면서 장박사님의 옥고를 어떻다고 얘기하기 어렵고 또 두렵기도 하지만 농업통계를 부분적이나마 실무에서 여러해 동안 다룬 경험으로 장박사님의 발표내용 중 몇가지를 저나름대로의 의견으로 말씀드리고자 합니다.

Stream and groundwater qualities of small agricultural watershed in Kangwon Probince, Korea were monitored 1 to 2 years, and the relationships between stream and groundwater qualities and seasonal water quality changes analyzed. Flooded paddy fields influenced groundwater level and quality during rice culture. The differences between groundwater levels during rice culture and non-culture spans were between 0.8 and 2.91 m. Seasonal changes of total nitrogen and nitrate nitrogen concentrations of stream and groundwater were very similar and groundwater quality was thought to have a profound impact on stream quality of the research watersheds. Suspended solids and BOD maintained the first degree stream water quality throughout the monitoring period except for a few and short flooding spans. The concentrations of total phosphorus and total bacteria of both waters showed wide variations and any seasonal trends were not observed. Long-term monitoring studies on small rural watersheds were recommended to understand the pattern of both stream and groundwater quality changes with respect to land use, season and cultural practice, and to apply the results to develop effective water quality management policies for large river and domestic water supply systems.

At the present time the cadastral sections has a document for constructing database of land register and commit to record the assessed cost of land in field. Kumjung-Ku, Pusan is a model in this study. It is possible to investigate the present land record by connecting graphic data with attribute data in author's program. AutoCAD make possible to connect graphic data with attribute data. Because of limitation of constructing database in AutoCAD, authors construct independent database in Clipper's circumstance. Database in AutoCAD and Clipper is connected to the menu-file in AutoCAD's circumstance.

라오스의 Houay Pano 유역은 상업적 조림으로 인해 2011년부터 2013년까지 급속한 토지이용 변화를 겪어왔다. 본 연구는 이러한 토지이용변화가 박테리아 거동에 어떠한 영향을 주는지 이해하기 위해 Soil and Water Assessment Tool (SWAT) 모형을 활용한 박테리아 거동 모델링을 수행하였다. SWAT 모형은 수치 표고 모델, 토양 특성, 토지 이용 등의 정보를 종합하여, 유역 내수량 및 수질의 변화를 모의할 수 있는 모형으로, 본 연구는 대표적인 분원성 지표 세균 (Fecal Indicator Bacteria)인 대장균 (Escheichia coli, E. coli)을 대상으로 모델링을 수행하였다. SWAT 모형은 지표면 위 박테리아를 1)식물 위, 2)토양 용액상, 3)토양 입자상으로 구분하여 모의한다. 각 상태로 분할된 박테리아는 소멸 (die-off), 씻김 (wash-off), 침투, 표면 유출을 통한 수계로의 이동 등의 단계를 통하여 유역 내에서 거동한다. 본 연구는 서로 다른 기후의 영향을 배제하기 위해 각 토지이용 시나리오를 (2011, 2012, 2013) 실제 기후 조건과 동일 기후(2011-2013 평균) 조건으로 분류하여 분석하였다. 실제 기후 조건에서 SWAT 모형은 표면 유출, 토사 유출, E. coli 거동에 대해 2011년부터 2012년까지 감소, 2012년부터 2013년까지 증가로 모두 동일한 양상을 모의하였다. 이는 강수량의 양상과 동일한 것으로, 강수량이 표면 유출의 양을 결정하고, 달라진 표면 유출에 따라 토사 유출과 E. coli 거동이 결정되기 때문이다. 하지만 동일 기후 조건에서는, E. coli 거동 동인인 표면 유출과 토사 유출이 비교적 일정해짐에 따라, 각 상태로 분할된 박테리아의 초기 부하량값이 E. coli 거동을 결정하는 주된 요인임을 확인 할 수 있었다. 따라서 초기 부하량 분할에 활용되는 엽면적 지수 (Leaf Area Index)와 분배계수 (BACTKDDB)의 정확도가 요구된다. 추가적으로 본 연구는 박테리아의 유입원인 비료 모델링과, LAI를 활용한 박테리아 초기 부하량 산정, 토양 특성 변수와 토지 이용 변수의 분리, 지하수를 통한 박테리아 거동 등을 중심으로 SWAT 모형의 한계점과 개선점을 제시하였으며, 본 연구 결과는 토지이용변화가 박테리아 거동에 주는 영향을 모형적으로 이해하고, 또한 추후 박테리아 모델링 개발에 도움을 줄 것으로 예상된다.
