The development of electronic technology brings the advent of electronic tacheometer which measures, stores and records automatically angles and distances. Electronic tacheometer is the surveying equipment that enable the acquisition of the 3-D terrain information, construction of the database and automatic drafting of the cartographic map. This paper aims at studying the system which can produce automatically the digital cartographic map by us-ing the electronic tacheometer. For this study, cartographic maps of a region are produced by a plane table and an electronic tacheometer and these is analysed. The results of this study show that digital cartographic map by electronic tacheometer is much more accurate and efficient than cartographic map by plane table.

The purpose of this research is to suggest the reasonable method of Network RTK surveying in future cadastral re-survey project through the accuracy analysis about Network RTK surveying achievement and the conventional TS-based confirmation surveying. To achieve it, we selected the experiment places and succeeded in achieving the result by Network RTK surveying about total of 307 parcel boundary point. We compared it with the result of confirmation surveying for cadastral, and it was shown that total connection errors of RMSE was ${\pm}0.1028m$ and total 48 places exceeded in the cadastral re-survey allowable error tolerance. The research suggested the practical alternatives in cadastral re-survey project after the comprehensive evaluation of those analysis results. Therefore, the author suggested development and adoptation of integrated electronic plane table surveying method. Moreover, we suggested unifying the first parcel boundary point method into the total station surveying and adopt the Network RTK surveying on the cadastral surveying inspection.

In the numerical cadastral surveying field, the cadastral surveying would be measured with the Total Station surveying (electronic plane table surveying) system that consist the Total Station for surveying and the computing system for recording and editing the measured coordinates data by the TS. This study would suggest the advanced method, which is used on the RTK-GPS instead of TS for surveying and the computing system for handling the coordinates data and mapping. As a result of this study, although the measurement accuracy of the RTK-GPS and TS surveying make no greate difference, the suggested method reduces the cost of time and work force with the TS surveying. Besides, the new survey method would be more efficient due to directly handling the data and mapping in the field.

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.

In these days, surveying instruments are developing rapidly and the precision is improving continuously. The reappearance of three dimensional terrains of a great precision are possible and the calculation of the area or the volume has a high precision due to the development of the technique of the spatial information system using computer. But actually, in construction site they calculate two-dimensional area using the traditional method, plane table surveying, planimeter, and then get ground surface area through timing the slope correction factor. In this study, I show the defect and inefficiency of the calculation of the area by the traditional methods and survey the area with Electronic Distance Measuring equipment and GPS instrument. With these data, we made the three dimensional terrain model and calculated two-dimensional area and ground surface area. After that, I compared areas that calculated by algorithm method of irregular triangle and analysis of grid method with standardizing the area that calculated by the traditional method. Finally, I suggested more effective and precise method in calculating ground surface area.
