The coordinate of cadastral control points located over the area of different surveying origins is computed in a single surveying origin by trilateration adjustment of GPS baseline measurements. In every different surveying origins, well-matched control points are selected and mutually coinciding coordinates are computed by free network adjustment. Then, the coordinate of the other control points over the area is computed by joining these points to the adjusted points. In practice, by using 18 points of Gari, 17 points of Gyeyang, and 33 points of Central origin in Incheon, the coordinates of total 68 points in every surveying origin are computed. Between the points of different surveying origins, it is found that there are quantitative differences in azimuth and scale factors and the approximate point coordinate of other surveying origins is calculated by correcting the scale and azimuth.

The existing cadastral record cannot meet various and changing demands on land information, improve user convenience, and raise administrative efficiency. In addition, three-dimensional parcels, or spatial objects about three-dimensional space cannot be registered in the conventional cadastral record. The limitation of cadastral information based on two dimensions is quite stressing the necessity of three-dimensional cadastral record. The purpose of this study is to develop new limns of cadastral record model in order. In register three-dimensional positions and right relations of land and buildings. This study examined land cases where space was being three-dimensionally used. As the result, cadastral record models both separated by steps and integrated were developed, which can contain matters of land, buildings, and right registration about three-dimensional land parcels. Also, this study suggested a method where a building can be separately registered according to it's the superficies division.

Prior to start the business of Cadastral Non-Coincidence, there is a difficulty in the boundary setting due to the border dispute between the business owners, because of inconvenient land using and problems and the exercise of the ownership about their shared land. Expected that the cooperation of the residents admission can be used as countermeasures, which lead to conclude in the agreement by converging various opinions, such as about preceding business promotion, property rights and stable boundary, into one submission. Consequently, the national stength can be competitive by the efficient land management; the land portion of utilized area would be increasing as well as the boundary would be more convenient and accurate. In this study, the Cadastral Resurvey is planned to be analyzed the complaints based on complaint resolution cases and problems associated with the Cadastral Non-Coincidence. Following to the result, we want to use it to analyze the actual situation of Cadastral Non-Coincidence in Gyeongnam, so as generated by the Cadastral Resurvey business in the future for efficiency in the business.

The Occurrence of cadastral land having difference between registered lists and realities result in not only enormous trobles on land administration of the nation but also violation of individual property rights. Government has inclined many efforts to solve this problems, it is actuality that results are not reaching in expectation. Therefore, the purposes of this study are to prevent problems beforehand and manage lands efficiently by analyzing typical realities and extracting the area of cadastral having difference between registered lists and realities.

Using the baseline vectors obtained by GPS observations on 32 triangulation points over Gyunggido area, Bessel coordinates of the corresponding points are calculated according to trilateration adjustment. The result shows the possibility of construction of a new cadastral survey network with the degree of correctness of 5cm, when newly computing the coordinates of the survey datum point of the area with values from GPS baseline vectors.

The cadastral administration is centered around cadastral maps. It is increasing that demand of the public for effective administration and higher quality of service through the development of application program of cadastral maps maintenance. Geo-Spatial Information System which is based on the graphic database of Yuseong-ku, Daejon City and the attribute database about cadastral information has been developed for effective maintenance and use in the part of map editing, public land price management and multi-parcel based work. In this pi-lot study, pointing out difficulties of database implementation and many experiences in the development of application program will be used effectively for further expansion of the automation of the cadastral administration.

To support the second step of Land Information System building, we are studied about the way of image(included map, document) input, computerization way of cadastral map and the program development which can efficiently carry out the application and update of the constructed digital data. The final object of this study is in raising the efficiency of the cadastral-map computerization, building an accurate DB and its speedy, efficient application. Because the program which was developed in this study is designed to fit the Cadastral Affair Computerization, the integration of the each division's affaires is possible. Because of it, we can raise the specialization of the works and we can reduce time and cost to build Data Share System and cadastral digital data.

The Government confirmed the action planning of digital mapping project for major thematic maps based on‘Revised Plan for The Development of the National Geographic Information System’(NGIS). Mapping for major thematic maps will selectively have produced the essential digital thematic maps according to the frequency of usage by the year of 2000. The models of topographic-cadastral maps around Suwon were produced in accordance with the presented draft. We presented specification for production of the most appropriate topographic-cadastral maps through the analysis of the process of production, discussion and error check, and correction of the produced topographic-cadastral maps. And we could make it easier to develop digital mapping project of topographic-cadastral maps effectively by presenting the strategy for data input and maintenance, the cost model for carrying out the digital thematic map production, digital topographic maps, and the supplement of data model and data format.

Cadastral control points in Korea are refered to various origins, for example an early separated small triangulation, a separated small triangulation, a separated control surveying origin and an unified origin. We determined transformation parameters from old origin to unified origin using 2D conformal transformation method. To evaluate of transformation accuracy, we compared with GPS field surveying results. And we experiment on coordinate transformations with unified results between the local geodetic datum and the new Korea geodetic datum.

The purpose of this study is to provide the ideal forecasting model of cadastral survey work load through the Economeatric Analysis of Time Series, Granger Causality and VAR Model Analysis, it suggested the forecasting reference materials for the total amount of cadastral survey general work load. The main result is that the derive of the environment variables which affect cadastral survey general work load and the outcome of VAR(vector auto regression) analysis materials(impulse response function and forecast error variance decomposition analysis materials), which explain the change of general work load depending on altering the environment variables. And also, For confirming the stability of time series data, we took a unit root test, ADF(Augmented Dickey-Fuller) analysis and the time series model analysis derives the best cadastral forecasting model regarding on general cadastral survey work load. And also, it showed up the various standards that are applied the statistical method of econometric analysis so it enhanced the prior aggregate system of cadastral survey work load forecasting.
