This study investigated the cadastral non-coincidence between real land using and cadastral book using Google Earth Web for difficult area to access that is more efficient method compared with field survey for saving time and money. An reading error has occurred eight parcels about dry field and paddy field but this method is more powerful in case of a danger area of steep, unregistered cemeteries of cadastral book using Google Earth Web of image interpretation that method takes 1 day, the accuracy is 96% and improved 20% more than field survey takes 5 days by 40 parcels. It's possible to reduce the manpower, time and budget could be minimized. In particular, it is need to land alteration of forests and fields category that finds 47 locations a burial ground of non register cadastre book. Google Earth Web method is enabling easy visual analysis of the future land administration of local governments to improving the reliability of temporal and economic costs can be very useful to reduce.

It is usual for the officially land price of agricultural field parcels to be determined by real estate appraisers's experienced knowledge and intuition without considering quantitatively physical factors that directly influence agricultural productivity. Solar radiation is the most important predictor of agricultural productivity. GIS based simulation techniques were used to evaluate correlation between the officially land price and solar radiation for agricultural field parcels. The results show that officially land price shows random distribution patterns in relation to solar radiation, which proves that officially land price for agricultural field does not reflect agricultural productivity. It is anticipated that this research output could be used as a valuable reference to support more scientific and objective decision-making in the official pricing process of agricultural field parcels.

본 연구는 수도권 농촌지역인 여주 지역의 토지이용 변화, 생활공간 변화, 생활실태의 변화 등을 살펴 급격하게 변화하고 있는 생활공간의 사례를 살펴 지역성을 규명코자 농촌성격이 강한 지목(예; 전, 답, 임야)과 도시적 성격이 강한 지목(대지, 공장용지, 도로용지 등)의 필지변화와 면적변화를 중심으로 토지이용의 변화를 살폈고, 지형도를 통해 과거의 마을에 비해 변해버린 생활ㆍ공간을 추적하였다. 설문지 조사를 통해 주민생활의 실태를 살폈다. (중략)

Cadastral map is a public book that has been composed by continuous parcel having location, number, classification, boundary and an area based on Cadastral Law. A few years ago, cadastral map had been managed by form drawn on 2 dimension plane paper with 7 regular scales. Recently as computer systems are upgrading, cadastral map was able to have a chance to develope one step. Its type has been remade from raster to vector. In result, the cadastral map of vector type becomes to apply variously. Therefore, digital cadastral map has been ready a system to be use with multi-propose by KLIS(Korean Land Information System). In this research, it concretely want presentation of status using land more than original parcel on basic coordination cadastral map and KLIS(Korean Land Information System). The cadastral map is composed as parcel unit was applied by new presentation technique to "Model Research on One Parcel Presentation Technique for Land Status of Cadastral Map". The function of cadastral map on One Parcel Presentation Technique which is not only location relation of possession right and expression of states using land in 28 classifications demonstrated on the cadastral law but also used as foundation data of GIS construct business is developed by lines and classification of parcel to center around public sites of roads, rails, drains and rivers. especially, this research is composed of technique elevation and development of One Parcel Projection Technique of cadastral map in using object of roads among public sites.

Landuse changes and cadastral information error categories in the four major river areas were analyzed for the use of policy data as cadastral re-arrangement of national and public lands would be required, using high-resolution air-photographs and cadastral maps before and after the river development. The study sites were the river areas of 40km around four dams of the Nakdong river where their landuses were changed most. As the results, national and public lands reached 79.9% of land parcels and 93.3% of land areas of the study sites similar with those of the four river areas, 84.3% of land parcels and 85.5% of land areas. The landuse classification of the study sites before the four river development was consisted most of 'river'(71.6%) and 'rice field'(12.3%), but after the development the 'river' was reduced to 42.7% and 'park area'(19.6%) including sport fields and 'mixed lots'(20.8%) were increased. Also, 86.7% of land parcels before the development could be reduced after the development if administrative districts and land ownerships were not considered. Cadastral information error categories can be found as cadastral polygon missing, polygon overlap, location and boundary non-coincidence, small polygon generation, and non-coincidence between cadastral boundary and river boundary. Landuse change monitoring method using air-photographs will be useful to analyze landuse state through fast information aquisition and to manage properties of national and public lands such as river areas.

The methodology on digital cadastre(World Geodetic System Conversion) needs to be specified because the primary target site is discussed for large national estate such as road, river etc. on nationwide. Comprehensively reviews on similar cases and literature reviews to make a methodology for digital cadastre on large national estate, cadastral map revision is required before converting to World Geodetic System. The revisions are on subdivision survey or the other surveys to the necessary area through inspection of geometry and attributes. And the researcher pointed out the need of registration conversion and union of parcel to remove small parcel or to remove the inconsistency of land use type. Basically a systematic maintenance of cadastral map is necessary because the World Geodetic System Conversion unresolved the poor cadastral map quality to digital cadastre on large national estate.
