  • In this study, one of the main aims is to build up a technical foundation for promoting the cadastral resurvey effectively and to improve the accuracy of cadastral surveying is to make use of precise surveying techniques in allowance of position errors as reference accuracy in cadastral resurvey, which is proper to obtain the sufficient accuracy of the cadastral control points, and parcel boundary points by introducing the GNSS-based surveying techniques on cadastral survey. In detail, the existing procedures and outcomes of cadastral survey were compared and analyzed for suggesting a better survey technique than that of the other techniques in a variety of aspects of capability of cadastral survey. The new skills and supports could be upmost importance when doing cadastral survey. What's more, essentially, 'The Measurement Department' makes all the efforts to establish 'The Surveying Regulations'. This could possibly apply GNSS-based surveying technique to the cadastral resurvey for the foreseeable future and this research paper suggested that how to improve absolute accuracy of cadastral reference points by means of putting to use the appropriate models of measurement further.

  • The current cadastral surveying is used digital cadastral map. This map is no local confirmation. Besides, Base cadastral map drawn up 100 years ago. And Graphical cadastral characteristic is difficult to ground boundary points restoration. Due to the lack of ground boundary points can cause land dispute and Cadastral Non-Coincidence. In this Study, Understand the concept of accuracy and error, Analyzing the current regulations. Also Comparative analysis of current cadastral regulations and other surveying regulations to suggest improvements to the cadastral surveying. The results indicated a clear definition of accuracy and error and The installation of permanent ground boundary points are needed. Uniform and consistent reference point system is needed. In addition, the accuracy provided by the landowner should understand. Cadastral Surveying Regulations require specific and detailed procedures.

  • This study is to analyze the accuracy of position determination in cadastral surveying using VRS GNSS(GPS/GLONASS), and is to suggest a possibility to improvement of accuracy in decision making of cadastral surveying result based on this result. As a result of this study, the position accurate of this study, which decides position combining with GPS/GLONASS satellite data is about 3cm more accurate than using only GPS satellite data. Therefore, if GNSS integrated receiving method is to be applied on cadastration, it can be expected to improve to estimate the position accuracy.

  • The existing calculation methods of the cadastral traverse survey was established in 1910s and are mostly outdated. The quality of these methods are not adequate to satisfy today's surveyor's needs that use a simple calculation method to distribute the error values. Thus, the main objective of this research is to find a methodology for appropriate calculation methods of the cadastral traverse survey that uses the general least square adjustment method with weight. Consequently, least square adjustment method has a better result than the previous one.

  • At present, the cadastral field, with the conversion into digital cadastral map management system, not the existing cadastral map management system, has gone through a lot of changes, such as the market opening of cadastral surveying and overseas launching of a cadastral field. Such an environmental change has brought on a lot of advantages, such as improvement in accuracy of surveying, efficient management system, and reinforcement of competitive power in cadastral surveying. However, the conversion into the advanced cadastral management system serves to relatively heightening the possibility of outflow of cadastral information and its technology in comparison with in the past. This research, with the aim to cope with indiscriminate outflow of cadastral technology, is aimed at suggesting the plan for the prevention of outflow of cadastral technique and its protection after examining and considering the contents of environmental changes in the currently going cadastral field.

  • Network RTK GNSS positioning technique which has been developed to overcome the limitation of Single reference station RTK is used widely in the field of general surveying, cadastre surveying and engineering surveying due to the high accuracy and efficiency. It is specified Network RTK, Single reference station RTK and Static of GNSS as a surveying method in the regulation of Cadastre Re-survey Surveying. In this study, Network RTK and Static GNSS surveying were accomplished at cadastral re-survey field in Hadong, Gyeongnam and the surveying results were compared. Also, to analyze the performance of site calibration in Network RTK surveying, two types of Network RTK surveying with and without site calibration were accomplished and the results was compared. The research result shows that average positioning error between Network RTK(VRS) without site calibration and Static surveying result is 2.44cm and 1.53cm respectively and average positioning error between Network RTK(VRS) with site calibration and Static surveying result is 0.19cm and 0.82cm respectively at two zone. So, it was proved the effect of calibration in network RTK(VRS) surveying.
