With the popularization of big data environment, big data have been highlighted as a key information strategy to establish national spatial data infrastructure for a scientific land policy and the extension of the creative economy. Especially interesting from our point of view is the cadastral information is a core national information source that forms the basis of spatial information that leads to people's daily life including the production and consumption of information related to real estate. The purpose of our paper is to suggest the scheme of big data analytics with respect to the articles of cadastral resurvey project in order to approach cadastral information in terms of spatial data integration. As specific research method, the TM (Text Mining) package from R was used to read various formats of news reports as texts, and nouns were extracted by using the KoNLP package. That is, we searched the main keywords regarding cadastral resurvey, performing extraction of compound noun and data mining analysis. And visualization of the results was presented. In addition, new reports related to cadastral resurvey between 2012 and 2014 were searched in newspapers, and nouns were extracted from the searched data for the data mining analysis of cadastral information. Furthermore, the approval rating, reliability, and improvement of rules were presented through correlation analyses among the extracted compound nouns. As a result of the correlation analysis among the most frequently used ones of the extracted nouns, five groups of data consisting of 133 keywords were generated. The most frequently appeared words were "cadastral resurvey," "civil complaint," "dispute," "cadastral survey," "lawsuit," "settlement," "mediation," "discrepant land," and "parcel." In Conclusions, the cadastral resurvey performed in some local governments has been proceeding smoothly as positive results. On the other hands, disputes from owner of land have been provoking a stream of complaints from parcel surveying for the cadastral resurvey. Through such keyword analysis, various public opinion and the types of civil complaints related to the cadastral resurvey project can be identified to prevent them through pre-emptive responses for direct call centre on the cadastral surveying, Electronic civil service and customer counseling, and high quality services about cadastral information can be provided. This study, therefore, provides a stepping stones for developing an account of big data analytics which is able to comprehensively examine and visualize a variety of news report and opinions in cadastral resurvey project promotion. Henceforth, this will contribute to establish the foundation for a framework of the information utilization, enabling scientific decision making with speediness and correctness.

"Master Plan of Cadastral Resurvey Project" aims to put the governmental budget of 1.3 trillion Won into the cadastral resurvey project until 2030 that reflects the preliminary feasibility study, conducted by government at 2012. The cadastral Resurvey, which takes 78.8% of the expenses in the project, has to take an critical role for earning the most effective results from the project. The cadastral confirmation surveying take up almost 13% of the project and is controlled under the areal SOC(Social Overhead Capital) projects in current "Master Plan of Cadastral Resurvey Project". Also, the affiliations of cadastral resurvey and linear SOC projects are expected to bring advanced results, although those are excluded from cadastral confirmation surveying. For linear SOC projects, the land division survey is conducted by using boundary stakes in boundary survey, while the cadastral resurvey is conducted within the SOC project area, after the completion of the project. In this study, we could conclude that cadastral resurvey results with the world geodetic system from boundary survey at the point of land division could be produced without the duplication of land division and cadastral resurvey. As a result, the expected benefits are 73,877 parcels and 4,078 million won, annually.

At a time when the demand for drones is increasing, a plan to utilize drone images was sought for efficient promotion of cadastral resurvey. To achieve the purpose of this study, the technical and legal status of drone images was reviewed, and through this, the possibility of using it for cadastral resurvey was primarily reviewed. subsequently, an experiment was conducted targeting the project district to examine whether drone images were applied to boundary extraction, which is the primary process of cadastral resurvey. As a result of the experiment, it was found that boundary extraction from images is possible. However, in some cases, it is impossible due to field conditions or image quality. Therefore, it is necessary first to apply cases where boundary extraction is possible to cadastral resurvey and seek solutions for some impossible cases. In particular, the image quality problem may have problems with the current technology, but it will also have problems with the existing drone equipment. So, standard for drone calibration should also be established. Finally, the cadastral resurvey surveying procedure using drones was also presented

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.

In this study, we tried to suggest a plan to improve the efficiency of operation after analyzing the actual conditions by selecting case areas operated by the cadastral resurvey responsible agency system. The research results are as follows. In the evaluation of the selection of a cadastral resurvey agency, a method to raise the qualitative evaluation score was suggested. The expansion of support for the cadastral resurvey agency made it possible to automatically connect and install when the LandyGo program is updated, and suggested that prior training should be stipulated in the related regulations. In the performance of cadastral resurvey surveying and division of duties, the installation of temporary boundary monuments and determine boundary monuments should be integrated. And this suggested the direction of conserving the project cost of the cadastral resurvey agency through joint implementation. Also, in the short-term and long-term perspectives, a plan for realization of project cost distribution in connection with the expansion of the entrustment of the cadastral resurvey responsible agency was presented. If the responsible agency system is operated by reflecting the results of this research, it is expected to improve the satisfaction of the project participants and shorten the project period.

The cadastral resurvey project has been planned for 19 years, from 2012 to 2030, which refers that now is at the beginning stage. The aim of a project was to correct the registration of cadastral register, which was not corresponding to the actual circumstances. As a national project, the government has been charged of this project to achieve the effective land management and protect the property rights of people, by changing analogue cadastral surveyed in 1910 to digital cadastral. On this paper, we focused on reinvestigating the principle of cadastral resurvey project and suggesting better solutions for problems, so as minimizing numbers of trials and errors in the project.

Since 1910 the enactment of the Land Survey Act, Special Act on Cadastre Resurvey was enacted after about a century and the Surveying for the Cadastral Resurvey Project will be scheduled by 2030. The establishing boundaries occupies an important proportion in this project and the regulation on surveying for the cadastral resurvey provide specific examples of the criteria for it. This regulation can be set according to not only ground boundary and cadastral boundary, but also customary boundaries of the relevant region and boundaries agreed between landowners. However, there is no standard rule whether to accept the agreement boundary and can be abused some problems. In addition, there is a question about the subject that agreement between individuals on the public record managed by the nation. In this study, boundary agreed in cadastre related subject is examined in depth and improvement proposal about the problems. The research results can be established evaluation standard of competent authorities of the cadastral records and the Surveying for the Cadastral Resurvey Project will be progressed smoothly with effective use of land.

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.

According to increasing the value of real estate and various land use by urbanization and industrialization, the importance of land use has enhanced regardless of above or below the surface. Therefore the changes into Digital Cadastre using high-technical surveying methods has tried to find a solution in the purpose of providing accurate land information to End-users in real time. However Korean cadastral system was established for a short time through the Land & Forest project and it has been used for cadastral surveying until now. Land devastation by the Korean war and the indiscreet land use by unplanned land development of industrialization has raised failures to construct correct cadastral records. So it has occurred that it becomes one of social problems due to the current unmatched areas between adjacent parcels. Therefore government has tried to make an effort to solve the problems such as reducing unmatched areas and introducing a Case study for Cadastral resurvey. And also it is necessary to adopt a suitable Korean model for Cadastral resurvey. In this study, the current Korean situation of cadastral surveying was investigated and the optimized models for various patterns of Land surveying was offered.

In this research, we would try to evaluate the applicability in cadastral resurvey surveying by analysing the accuracy of building boundary surveying using the reflective sheet total station surveying. When we analyse it, we refer the reflective sheet which can supplement not only the difficulties of total station surveying and GPS surveying caused by the diversity of the building structure but also the errors of non prism total station caused by material of the object. Each reflected angles $90^{\circ}$ and $60^{\circ}$, $30^{\circ}$ of RMSE results were analyzed by RMSE between 1.2mm~2.8mm and 2.2mm~4.0mm, 2.5mm~4.4mm for each distance. The result of X RMSE was analyzed to be 0.0043m in a boundary surveying for existing building between prism surveying and reflective sheet surveying, and also Y RMSE was 0.038m. The source of error is estimated that the body of the prism can not be exactly attached to the edge of a building. Therefore, it will be very helpful to use a reflective sheet surveying with a prism in both the limit of collimation and error reductions as a building boundary measurement in cadastral resurvey surveying.
