  • The field of land surveying is changing dramatically due to the way data is processed, analyzed and presented. Also, there is a growing demand for digital spatial information, coming primarily from the GIS (Geographical Information System) user community. Such a demand has created a strong development potential for a new land surveying software. An overview of the development and capabilities of a land surveying software platform based on the Windows system, SurveyingMap, is presented. Among its many features, SurveyingMap provides a lot of adaptability for networks adjustment, geodetic and plane coordinates transformation, contouring, sectioning, DTM (Digital Terrain Model) generation, and large scale mapping applications. The system output is compatible with well known computer aided drafting (CAD) /GIS packages to expand its scope of applications. SurveyingMap is also suitable for non-technical users due to the user-friendly graphic user interface. The system could be used in engineering, architecture, GIS, and academic teaching and research, among other fields. Two applications of SurveyingMap, extension of field control and large scale mapping, for the case study area are established. The results demonstrate that the system is adaptable and reasonably priced for use by college and university students.

  • This paper analyzes three theories for land degradation assessment and internationl/domestic methods for land degradation monitoring and assessment. Under the guidance of absolute degradation thought, this paper proposes the technological framework for monitoring and appraising cultivated land degradation based on the 3S technique. We can apply 3S technique and analyze the nature, the environmental, the social, and the economic elements which influence the land utilization and degradation synthetically, to set up the indicator system of the cultivated land degradation monitoring and assessment based on 3S technique; to propose the degradation information extraction methods based on 3S technique; to create the quantitative assessment model and method for land degradation; to analyze the ecological environment response of land use and degradation quantitatively; and to propose the measure, policy and suggestion for solving the land degradation problem from the point of view of land utilization.

  • The cadastral boundary points which cadastral surveyor presented on the ground by conducting cadastral surveying represents the limits of land ownership and give binding force and determination power. However the land disputes have increased these days mainly due to cadastral registration errors, surveying errors and land owners recognition error. In these cases, the cadastral survey interests try to find solution by either a administrative procedures by appealing civil complaint or border determination litigation through court. The neighboring residents and related organization have difficulties in resolving the civil complaints. In this study cadastral surveying and cadastral boundary determination process has been reviewed and the results of cadastral surveying screening by Central Cadastre Committee from 2016 to 2021 have been classified. The outcomes of this research will be used for cadastral surveying and contribute for reducing land disputes and improve reliablity of cadastral surveying.

  • 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.

  • Korea's inspection of cadastral surveying value is carrying out based on cadastral law, and has to enter in cadaster after government office's final inspection of cadastral surveying of land alteration according to the request of land owner or the state. Therefore, government office has to inspect the value of surveying before arranging cadastral book, and has to confirm whether the surveying error is whithin the range of allowing one. If it is, a govenment office has to arrange the cadastral book according to resulting Value. This study investigates and analizes annual land alteration of Sungnam city and analizes the situation of government office's cadastral surving value, the number of inspectors, and equipments. As a result, this study shows the problem and provides effective basic materials, increases the efficacy of the state's cadastral surveying inspection, and minimiges land dispute.

  • When a boundary dispute occurs between landowners of adjoining lands, a court deals with a boundary violation on the basis of cadastral register. Boundary relocation surveying is one which reconstructs a boundary in cadastral register on actual land. Boundary relocation surveying includes most of surveyings related with the civil case such as restoration of land and demolition of building and a surveying result affects a ruling critically. However, boundary relocation surveying depends on surveying technician's knowledge and experiences and can lead to different surveying results. This study reviews legal principles of boundary relocation surveying by analyzing law practice of boundary relocation surveying which is used for solving a boundary dispute between landowners of adjoining lands and by examining related laws and Supreme Court precedents. The study seeks to contribute to consistent and reliable results of surveying by leading surveying technician to carry out a boundary relocation surveying on the basis of judicial doctrines.

  • Automatic land use and land cover change (LUCC) detection via remotely sensed imagery has a wide application in the area of LUCC research, nature resource and environment monitoring and protection. Under the condition that one time (T1) data is existed land use and land cover maps, and another time (T2) data is remotely sensed imagery, how to detect change automatically is still an unresolved issue. This paper developed a land use and land cover class knowledge guided method for automatic change detection under this situation. Firstly, the land use and land cover map in T1 and remote sensing images in T2 were registered and superimposed precisely. Secondly, the remotely sensed knowledge database of all land use and land cover classes was constructed based on the unchanged parcels in T1 map. Thirdly, guided by T1 land use and land cover map, feature statistics for each parcel or pixel in RS images were extracted. Finally, land use and land cover changes were found and the change class was recognized through the automatic matching between the knowledge database of remote sensing information of land use & land cover classes and the extracted statistics in that parcel or pixel. Experimental results and some actual applications show the efficiency of this method.

  • Using soft classification, it is possible to obtain the land cover proportions from the remotely sensed image. These land cover proportions are then used as input data for a procedure called "super-resolution mapping" to produce the predicted hard land cover layers at higher resolution than the original remotely sensed image. Superresolution mapping can be implemented using a number of algorithms in which the Hopfield Neural Network (HNN) has showed some advantages. The HNN has improved the land cover classification through superresolution mapping greatly with the high resolution data. However, the super-resolution mapping is based on the spatial dependence assumption, therefore it is predicted that the accuracy of resulted land cover classes depends on the relative size of spatial features and the spatial resolution of the remotely sensed image. This research is to evaluate the capability of HNN to implement the super-resolution mapping for SPOT image to create higher resolution land cover classes with different zoom factor.

  • 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.
