Chilli reservoir is agricultural purpose reservoir made in 1945. But its bottom is covered with thick accumulated sewage layer, so its original function has failed. This study conducted cadastral state surveying to survey the state of this area prior to dredging the accumulated bottom sewage layer of Chill reservoir. Prior to cadastral state surveying we analyzed the digital map and aerial photographs of study area. In cadastral state surveying, traversed network was constructed on the road and banks near the reservoir, a surveyed map was made by surveying with Auto-reduction EDM Alidade. From the comparison results of the cadastral map and digital map, we found small chilli reservoir is expressed as rice field on the digital map, and it should be corrected. And when we make digital map and topographic map, the errors will be diminished if we use the cadastral map at the same time.

This study has based on RTKGPS and DGPS and Digital Video Camera to 3-dimensional position data of road, as a Road Spatial Information. Economic efficiency analysis was applied to road spatial information system built up by four different methods such as conventional surveying, RTK GPS, DGPS, and Digital Video Camera. As a result of analysis, it was shown conventional surveying 100%, it was shown that about 64% in RTKGPS, it was shown that about 63% in DGPS, it was shown that about 37% in Digital Video Camera cost-saving.

GPS(Global Positioning System) surveying is an effective method using satellite measurement system and can be applied to construction of digital map of irrigation canal networks. In this study, GPS surveying method for irrigation structures was developed. A selected main canal of an irrigation district were surveyed by GPS. The obtained surveying results were corrected by post-processed DGPS (Differential Global Positioning System) and imported to GIS for the digital map construction.

현제 지적업무는 대장(토지대장 및 임야대장)과 도면(지적도면 및 임야도면)의 전산화를 통해 디지털 지적관리체계로 전환되어 운영되고 있다. 지적측량 방식 역시 GPS측량, 전자평판 측량 등의 디지털 측량방식이 이용되고 있다. 지적측량에 따른 수수료는 현재 건설표준품셈과 국토교통부 자체 고시에 따른 기준을 기초로 산정하고 있다. 그러나 현재 고시되어 있는 지적측량수수료 산정 품셈은 종목에 따라 전산 환경을 반영하지 못하는 경우가 있다. 본 연구에서는 빠르게 변화하고 있는 디지털 지적관리 환경에서 개선을 필요로 하는 지적측량수수료 체계를 분석해 이에 대한 개선방안을 제시함으로써 디지털 환경에 적합한 지적측량수수료 체계 확립의 기반을 마련하고자 한다. 연구 성과로는 현황 분석을 토대로 디지털 환경에 적합한 용어의 변경 사용(부동산종합공부시스템), 새로운 품셈 종목에 관한 품셈체계 마련(지적기준점의 현황 조사 및 관리), 지적확정측량 품셈의 재조사 및 품셈 체계 마련을 제시하였다.

The subjects of this study are to examine and to apply the methods of making 1:5,000 scale maps using 1m resolution stereo images of IKONOS for the Munsan area of Paju-city where aerial photo surveying cannot possible because of security conditions. GCP(Ground Control Point) were acquired from GPS surveying and were to perform geometric corrections on images. Digital Map used IKONOS stereo images and it worked from the digital analytical stereoplotter. From field investigation, RMSE errors of the plane and vertical positions are estimated to 1.706m and 1.231m, respectively. The plane accuracy is better than an accuracy required by NGIS (national GIS) programs. Local information from field investigation was added and the resulting maps should be good as digital map under the scale of 1/5,000.

Currently, aortal surveying is getting advanced in the world. New digital equipment for aerial surveying makes improvement of accuracy, economical efficiency and reduces cost. for a result, however, there are required to produce a accurate product. In this study, we used two kinds of data, the one which used only GPS/INS data and the other one which used GPS/INS data added on GCPs from digital maps, and made as a mosaic to compare both of them whether which one is better based on digital maps. the result is that the data which used GPS/INS data added on GCPs from digital maps was a lot better than GPS/INS data.

본 연구에서는 막대한 비용과 노력을 들여서 제작된 수치지도의 위치정확도를 실험적으로 판단하고자 하였다. 수치지도의 위치정확도 평가를 위해서 GPS와 Total Station을 이용한 현지측량을 실시하였으며, 현지측량의 성과와 수치지도를 비교함으로써 1:5,000 수치지도의 위치정확도를 판단해 보았다. 그리고, 1:5,000 수치지도의 이론적인 기대정확도와 현지 측량성과를 비교하여 향후 수치지도의 위치정확도 평가방법 및 개선을 위한 연구방향을 고찰해 보았다.

Recently, the old surveying method for acquiring surveying-geo information results had a low economic efficiency and a low dependence of precision because it took much times and high costs. So, we acquired law data by execution of control surveying through Static positioning of DGPS(Ashtech). It is computed plainmetric(X, Y) positioning through postprocessing by Prism S/W. And we computed height(Z) through control surveying by ring-closed leveling surveying. After control surveying execution, we built DEM(Digital Elevation Model) using LDT S/W and accuracy 3D detail surveying by EDM(Electronic Distance Measurement) surveying. The purpose of this study was to yield automated digital mapping and the automated amount of materials using ahead data. The conclusions were as follows; First, we built the automated amount of materials system and got high efficiency about personnel, times and precision. Second, when, people precisely positioned on railroads of a high-speed railroad and used GPS surveying, the result was permitted. Finally, it was possible to draw automated profile and cross-section using the 3D terrain model build with the DEM technique.
