Shoreline Investigation Survey in Korea 2001 Taean ended 2009 Tongyeong with start, Gosung in 2010 to survey the shoreline plans to complete the survey. Shoreline Investigation Survey of the country shape formulation and accurate coastline produced to by 2007 baseline survey, level survey, the terrain level survey, water level survey, tidal observations, property survey, etc was conducted. Since 2007 the status of topography survey were performed by replacing the Airborne LiDAR survey. In this research study surveying the shoreine of the business status, issues, improvements in the updated plan to analyze the shoreline land department future research and surveying the shoreline Island department plan is presented.

The objective of this study is to improve the survey rate and reliability of survey control point marks, which serve as the foundation for location-based services. Within the scope of this research, we have inspected the current status and reporting systems for national control point marks, public control point marks, and cadastral control point marks, identifying various issues. To tackle these challenges, we have prepared proposals for new unit cost calculations for national control point mark inspections, enhancements to the inspection and reporting systems for survey control point marks, and preliminary reporting procedures for surveyors using these control point marks. Additionally, we have established a workflow to refine the process of survey control point mark inspections and have proposed an automated system for calculating the unit cost for unreported targets. The study anticipates that these changes will improve the efficiency of future survey control point mark inspection tasks.

Nowadays 3D terrestrial laser scanners record high precision three-dimensional coordinates of numerous points on an object surface in a short period of time. So terrestrial laser scanner is applied to a wide variety of fields including geodesy, and civil engineering, archaeology and architecture, and emergency service and defence, etc. This study deals with the potential application of terrestrial laser scanner in the reconnaissance surveying. The results shows that terrestrial laser scanner is possible to extract the linear features and the positioning accuracy of objects measured by total station surveying is comparative to that by terrestrial laser scanner. Thereafter, it is expected that the potential applications of terrestrial laser scanning will be more increased by combining terrestrial laser scanners with airborne LiDAR (Light Detection And Ranging) and photogrammetric technology.

Nowadays, it grows bigger the importance of water resource management, and so, hydrographic surveying technology in river is important because it serves basic data about river environment. And, also, the application field of GPS has been increased and expected to be more increased because of the change of the geodetic reference system to World Geodetic System. In this study, hydrographic surveying in Hwang river in Geochang is accomplished by RTK GPS and Total Station and they are compared and analyzed the both results. The section profile in river is made by Hec-Ras program and CAD. The results show it can be saved 15.3% in surveying times and the amount of surveying works can be enlarged 42.5%. And the standard error between RTK results with calibration and the results without calibration turned out as 2.1 cm. So we have a conclusion that RTK GPS is more efficient surveying method than total station in hydrographic surveying in river.

This study presents the detailed methods for facilities mapping using GPS and Totalstation. From the control survey by GPS network adjustment, the level of significance fur the height value of fourth order triangulation stations used in this study was estimated about 10cm. According to the result of verification for the transformation coefficients of national coordinate, which were announced by the National Geographic Information Institute, RMSE f coordinate transformation was found out as $\pm$0.546m that can be applied to a map scale less than 1/10,000. The accuracy analysis of height determination by Totalstation for the traverse points spaced average 90m showed that RMSE came out $\pm$9mm on the basis of direct leveling, so it indicated that trigonometric leveling by Totalstation was correct comparatively. The result of accuracy analysis of GPS/RTK surveying on traverse points showed that RMSE came out $\pm$33mm in horizontal location on the basis of Totalstation's outcome and $\pm$15mm in height value on the basis of direct leveling. In the construction survey, GPS/RTK surveying is quicker and more economical than Totalstation surveying in the feasible areas of GPS surveying. but there were many impossible areas for GPS/RTK surveying by the obstacles like a building.

Current surveying and spatial information technology incorporates information and communication technology and is user friendly. However, it is not convenient to use in the field because a connection to a computer, such as a laptop, tablet PC, or desktop PC, is needed to obtain the survey results and the coordinates of the surveyed points. To solve this problem, we developed an app that can display surveyed data on a map and the current survey results through a connection between a total station and smartphone using a Bluetooth wireless communication device. The app allows users to perform field work simultaneously with office work in the field, because it consists of Bluetooth, closed traverse survey, current status survey, and coordinate conversion modules. The proposed app should increase user convenience and the operational capability of the total station in the field.

This study is to analyze open work status and conditions of cadastral surveyors and suggest improvement plans for working area of cadastral surveyors. The results are as below. Based on the analysis, this study suggests expansion of confirmation surveying for cadastral target range, ease of confirmation surveying standard for cadastral, and broader participation opportunities for cadastral surveyors in the cadastral re-survey project as improvement plans. If the Ministry of Land, Infrastructure, and Transport seeks legislative and policy improvement that can create more rational and ideal cadastral surveying conditions based on various reviews on improvement plans for working area of cadastral surveyors in this study will promote symbiotic development among cadastral surveyors.

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.
