Web Server Construction for the Adjacent Facility Management of Subway
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 21, issue 3, 2003, Pages 193~198
The population is increased in the area of a subway station because the accessibility of passengers is improved. Therefore, facilities for commercial purpose are concentrated in this area. To develop the station area as the center among the most urbanized area, overall mater plan should be constructed far the station area. This study was to construct web server for management a variety of 3D spatial object database of station areas using GIS and web 3D technology. These results will be used to manage efficiently a urban space by the connection of a subway station and a adjacent facilities.
Accuracy Analysis of Positioning Supplementary Control Point with the Combined GPS/GLONASS and TS
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 21, issue 3, 2003, Pages 199~207
In the study, the open area keeping a few visible satellites and the urban area covered with the high building, an electric pole were chosen far evaluation of accuracy of satellite positioning. First, suggest the validity of GPS/GLONASS, TS/RTK-GPS, and compared the accuracy with that of the classical surveying method. As a result, In static relative surveying, the difference of between the known cadastral supplementary control station and that of the acquired is 0.000∼.0006m in GPS alone, GPS/GLONASS, and In the RTK-GPS/TS, 0.010∼0.077m on the non-ambiguity fixed solutions in the urban area 0.008∼0.078m in the open area. it proved to be valid because it is within the allowed connecting errors, i.e 12cm on the baseline of loom in l/l,200 cadastral map.

The tasks in the cadastral field are being carried out by the aid of Parcel Based Land Information System which is equipped with both graphical and textual information acquired by the Cadastral Map Computerization Project. This have the purpose to present efficient surveying method as analyzing the accuracy about the field map We can also avoiding the drafting error caused by graphical cadastral and technical error including scale and contraction error as inverting an existing surveying system to the computer surveying system with this data.
A Study on Data Dictionary of Small Scale Digital Map
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 21, issue 3, 2003, Pages 215~228
National Geography Institute(NGI, National mapping agency) has been producing national basemap in automated process since middle of 1980's toward the systematic and efficient management of national land. In 1995, Korean government initiated a full-scale implementation of the National Geographic Information System(NGIS) Development Plan. Under the NGIS Development Plan, NGI began to produce digital maps in the scales of 1:1,000, 1:5,000, 1:25,000. However, digital maps of 1:250,000 scale, which are currently used for national land planning, were not included in NCIS Development Plan. Also, the existing laws and specifications related to digital maps of 1:250,000 scale are not clearly defined. It is fully appreciated that data dictionary will be a key element for users and generators of digital maps to rectify the existing problems in digital maps as well as to maximize the application of digital maps. There(ore this study proposed a feature classification system, which defines features that should be represented in digital map of 1:250,000 scale, and data dictionary as well.
A Study on the Kinematic Surveying Method Using the Digital Video Recorder
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 21, issue 3, 2003, Pages 229~236
This study recorded an object using a digital video recorder, and then tried to estimate 3-D positional information and to reconstruct an image. Firstly, the accuracy of measurement results from a video recorder was evaluated and tested for an applicability, then it applied to a real object to construct 3-D digital model. This study assumed that there is no lens distortion in a video recorder, and all bundles should precisely pass through the projection center of a lens. The image size for orientations is determined by the size of CCD chip and the number of pixels. The average squared error from the result by a digital video recorder and that by triangular survey from 1-second theodolite shows 0.0173m error in x,y coordinates. Without knowing the accurate information on the lens distortion and the coordinates of the projection center, this study reasonably produces acceptable results in the reconstruction of 3-D model. In consequence, this study found that the image from a digital video camera can be reconstructed 3-D model only from the information on a camera type.
Analysis of Position Accuracy for Underground Facility Using RTK-GPS
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 21, issue 3, 2003, Pages 237~243
The complicated facilities on the ground have begun to be laid under the ground as increasing emphasis on the beauty of cities due to centralization. But, as the kind of the facilities have been concentrated on the narrow area, accidents occur due to the difficulty of maintenance and the inaccuracy of location information. In this study, first we constructed the field test model to compare with the method of underground probing. So, we could know that the electromagnetic induction method and GPR(Ground Penetration Radar) are useful. It was acquired the position information for the underground facilities using a RTK-GPS. As the result, we have analyzed the accurate position of the underground facility and show the way improving accuracy in detecting and surveying comparing with the traditional surveying method. Also, we hope to contribute the effective maintenance and prevention of disasters to the underground facility as using underground facilities 3D position with Arcview and building the DB of exact depth and underground facilities information system.
Evaluation for Geometric Calibration Accuracy of Zoom-lens CCD Camera
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 21, issue 3, 2003, Pages 245~254
Zoom lenses CCD(Charge Coupled Device) cameras have many desirable features but appear to be geometrically unstable and diffcult to calibrate. It is well blown that the zooming camera parameters change with zoom lens position. This paper presents a comparative study of two approaches, namely, DLT(Direct Linear Transformation) introduced by Abdel-Aziz and Karara and the model proposed by Tsai, to evaluate the camera parameters of zoom lenses CCD camera and 3D positioning accuracy. As a result, the accuracy for 3D positioning using Tsai and DLT model is similar in both methods when the set of GCPs and the object are arranged in the same space. However, Tsai model is more stable than DLT in the case that the object is apart from the set of GCPs. Also, the further study for the parameters optimization of conventional DLT is needed to improve accuracy for 3D positioning.
Modeling Methods for SPOT-5 HRG Stereo Pair Images
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 21, issue 3, 2003, Pages 255~260
In this paper, we generate the 3D geometric sensor model of SPOT-5 HRG stereo images which are processed in Supermode and have 2.5m ground spatial resolution, and calculate the RPC(Rational Polynomial Coefficients) for acquisition of topographic information using the exterior orientation parameters which are determined in the 3D geometric sensor modelling process. It is shown that SPOT-5 images can be modelled with me 3.3m accuracy by the bundle adjustment method used to model the existing SPOT series. Considering the accuracy of RPC's results with rmse 0.03m accuracy, the RPC model can replace the sensor model, if we emphasize the simplification and the cost.
Extraction of Land Surface Change Information by Using Landsat TM Images
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 21, issue 3, 2003, Pages 261~267
We are able to simultaneously extract the land surface change information, as we input each information extracted from images classified during the two periods, as the attribute information of geographic information, and then use it a parameter of GIS. Hence, this research sought to present basic data far efficient management and development of land surface, together with land use trends, by using the remote-sensing technique enabling the acquisition of the land surface covering information, as well as the benefits of GIS. The research conducted a study on the extraction of land surface change information, and made it possible to treat image information easily compared to the existing image classification methods, thereby making it easy to know the land surface change process for each pixel.
Analysis on Pilot Survey for Cadastral Non-correspondence Arrangements
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 21, issue 3, 2003, Pages 269~275
The cadastral system which accomplishes the base of national land administration with accuracy of proper data and the cadastral maintenance quickly is agreeing with the actual place in information ages in Inundation. But even in spite of many efforts, various Problems are exposed in accuracy of the data on the cadastral maps and local situation must agree accurately from the process which propels cadastral information systems. Therefore, it must be carried out the cadastral non correspondence arrangement first of all in link of the plan which it corrects the error of existing data and computerization quickly. It summarizes the research as follows ; Cadastral non correspondence of the land boundaries on the map and actual circumstance does not agree with cadastral maps accurately, The lands which exceed the standards with the position error excess of 50cm on lil ,200 and 240cm on 1/6,000 areas on the map scale are the registration correction objectives. It is investigated that the cadastral non correspondence parcels occur in various cause and long period, the area error corrections are mainly objectives, and about 80% of the test area comes to reveal within permitted the limit of the measurement of planimetric area for cadastral survey, so it is not difficult with the fact that the compensation back which it follows in area increase and decrease and the location error correction becomes the important object fer the cadastral non correspondence arrangement projects.
Quality Improvement on Aerial Photographs
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 21, issue 3, 2003, Pages 277~287
As primary source data toward the systematic and efficient management of national land, the aerial photographs have been utilized in many different areas. However, the quality of aerial photographs does not meet the requirement of the users due to unidentified miscellaneous reasons. Aiming for the improvement of the quality of aerial photographs, we first investigated the current status of domestic rules and working procedures related to aerial photographing and film processing in great details. In addition, we investigated and analyzed those of advanced nations such as U.S.A., Canada, G.B. and so on. It was drawn from the comparison and analysis that the poor quality of domestic aerial photographs resulted from lack of the quantitative and objective standards on aerial photography specification as well as poor condition and aging problem of equipments such as aerial camera and film developing equipment. In this paper, we proposed a stepwise strategic plan which consists of the aerial photography specification and quantitative quality control standard taking into consideration the current status of domestic rules and working procedures.
