A Basie Scheme about the Determination of Official Coordinates of Geodetic Control Points in Korea
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 8, issue 1, 1990, Pages 1~13
The main objectives of this study are to present the new geodetic coordinate system, reference ellipsoid, and the basic scheme about the determination of official coordinates of geodetic control points. Moreover, provisional official coordinates on the basis of precise geodetic survey (1st and 2nd order geodetic networks) are proposed.
The Effect of Network Geometry on Three- Dimensional Analysis in Close-Range Photogrammetry
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 8, issue 1, 1990, Pages 15~22
The purpose of this study is to suggest possibility to analyze the three-dimensional positions of the whole surface of an object simultaneously and precisely by close-range photogrammetry. For this purpose, the geometry of network, namely imaging geometry and control configuration etc was considered, and then the whole surface of the object was analyzed by bundle adjustment through forma. lion of strip and block with which cover the whole surface of the object. As a result, we were able to prove possibility of the whole surface analysis of an object and to extract characteristics of accuracies in accordance with the number and configuration of control points. Also as desirable accuracies were able to be acquired even by employing configuration of only a few control point stationed on a limited surface, it is expected that the difficulties of control surveying will be able to be reduced considerably.
The Effects of Redundants in the Hybrid Networks
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 8, issue 1, 1990, Pages 23~30
This paper is a study on the adjustment of hybrid network of which the redundants effect its precision. To estimate efficiency of triangulation, triangulation and hybrid networks, this study analyzed the variation of precision to the change of the number of redundants. In the result of this study, the RMSE of the hybrid network was decreased 78 to 82 percent in semi-major axis, 48 to 60 percent in semi-minor axis to the triangulation and 84 to 87 percent in semi-major axis, 29 to 45 percent in semi-minor axis to the triangulation. The corelation with the number of redundant between the precisions is the function of y=464.71429x＋13517.57143. The interease of the number of the redundants can improve the precision, but because the number of redundants is very important in the surveying economics, the optimum number of redundants must be studied in the future.
A Study on the Basic Planning of Country Club Using Photogrammetry
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 8, issue 1, 1990, Pages 31~40
In this study, sample area was selected to compare the conventional method with photogrammetic method in basic planning of country club. Also various elements of planning, such as vegetation and water system, were considered through interpretation of aerial photographs and topographic maps, vegetation maps and water system maps were made as well as digital terrain models. These were used to analyse tophographic changes and landscape. As a result of comparing with the conventional method, it was shown that photographic interpretation could give more detail values than the conventional method, and that the digital terrain model could predict changes of topography, landscape and water system with more asccuracy. Consequently, the method of digital terrain model and photographic interpretation proved to be more effective than the conventional method in the case of water treatment, and planning of landscape and land utility.
A Study on the Earthwork Calculation Using Photogrammetry
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 8, issue 1, 1990, Pages 41~50
The purpose of this thesis lies in proving the practicality of photogrammetry and in promoting photogrammetry in earthwork which plays a major role in civil engineering projects. Analysis of accuracy in the determination of ammount of earthework was done by applying interpolation methods in digital terrain model. As a result of analysis of the data acquisition method, in cross-section method produced acceptable accuracy from Simpson's three-eighths rule and prismoidal rule. In results DTM, we have obtained the fact that earthwork calculation accuracy was increased by applying two or more interpolation methods. Therefore, the method by digital terrain model using aerial photograph has proved to be more efficient.
Simultaneous Adjustment of Closed Traverse Net Considered the Observed Angle and Distance
Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, volume 8, issue 1, 1990, Pages 51~56
Recently, Electronic Distance Meter(EDM) is widely used for the traverse surveying and trilateration net. In this study, the closed traverse network is precisely adjusted by simultaneous adjustment of the observed angle and distance, using the Electronic Total Stations (Set 3). And also, it is examined that each kind accidental errors appear observed angles according to the observed distance and the number of repeating angle. In addition to the result, of checking between the simultaneous adjustment, the compass rule and transit rule, simultaneous adjustment in combination of the observed angle and distance is more accurate and effective than other adjustment.
