Analysis of Precision According to Photographing Position in Close-Range Digital Photogrammetry
Seo, Dong-Ju ; Lee, Jong-Chool ;
Journal of Korean Society for Geospatial Information System, volume 11, issue 3, 2003, Pages 3~11
This study has made photographing respectively by changing the photographic distance, converging angle, picturing direction by use of Rollei d7 metric and d7
that is a measurement digital camera. And also in order to minimize the errors happened at the relative orientation, we have sorted out the round target that the relative orientation is automatically on the programming and have calculated RMSE by carrying out the bundle adjustment. We think that such a study could be used as very important basic data necessary in deriving the optimal photographic conditions by the close-range digital photogrammetry and in judging such a degree.

Although more than 90% of the yearly freight has been made through shipping the positioning system for the ships and cargos to support effective transportation of the freights has not been established yet. The government has been working on developing such a positioning system in many perspectives. The main problem in building a such system is that individual shipping companies are running different types of system and databases. This would cause duplicated investment with wasting money and time and this becomes an obstacle to the easier information sharing. Therefore, this study has mainly demonstrated developing a manager's system in the positioning system for the ships and cargos based on client-server scheme using electronic nautical charts on which the international standards are already available. In addition, this study also proposed an independent system which can be used in the ports with different locations thereby preventing duplicated investments.

Currently, the efficiency of GPS has been increased in the various precise survey like as the control survey and the navigation etc. Also, it is widely used in the deformation analysis of the structure, the measurement of the marine tides, the measurement of the river level and the topographic monitoring of seabed or riverbed by combined the measurement equipment for depth. In this study, we intend to increase in efficiency of the topographic monitoring of seabed or riverbed by combined with DGPS, RTK GPS and echo sounder. For this study, we defined the error correction of the echo sounder with the experiment of water tank which is considered the characteristic of estuary riverbed and then we developed the s/w for 3-dimensional monitoring of estuary riverbed and applied the s/w to field test and improved the various problems. On analyzing topography of estuary riverbed by combined GPS with echo sounder, the draught error which is yielded to change of length from the water surface by the movement of survey vessel to the end of the transducer was eliminated by geometrical rearrangement and we defined the correction formula
. The sounding error about the echo sounder and characteristic of estuary riverbed was found by understanding the relation of average diameter ind residual error and we defined correction formula,
by the regression analysis. and then we verified applicability of correction formula.
Development of Rivers Management system to Decrease flood Disaster using GIS

In these days, damages from localized heavy rain or typhoon are increase and people are making constant effort to work out countermeasures. Especially, by apply GIS with prompt extraction of information and objective analysis, we could demonstrate more effectively. For that reason, in this research we make the connection between rainfall-runoff model and HEC-RAS which calculate automatically and inquire out the dangerous zone easier way by describing the result with the connection between the Map Object and MFC. Most of all, this research will be very useful to forecast and prepare the disaster because it could plot plane figures, longitudinal sections and cross sections at the same time to help understand the damaged situation.
A Basic Study on Speciality and Standardization of Marine Geographical Names in Korea
Choi, Yun-Soo ; Han, Kil-Soo ; Lim, Young-Tae ;

Marine geographical names refer to the names for the geographical forms in nature such as oceans, straits, bays, inlets, and channels as well as the various undersea form including reefs and trenches. Marine geographical forms, lying under the sea, are different from those in land and are related directly and indirectly to the safe navigation of ships, that is, property and life of human beings. Marine geographical names have not been correctly named and used so far as in the case of using the name 'Sea of Japan' instead of 'East Sea' Marine geographical names have been created arbitrarily from various sources including researchers, institutes, and academic societies, which leads to confusion and makes it difficult for those to be acknowledged internationally. This paper examines the uniqueness and technicality of marine geographical names and analyzes the efforts and status for the standardization processes in Korea.
A Study on the Computation of Curve Number Using GIS

Recently, there is studying about slope analysis according to cell size and affect in conformity to determination of hydrologic topographical parameters the cell size a classified map scale about subwatershed. In this study, we wish to offer the base data to determination of hydrologic topographical parameters request of runoff model analysis in this basin on the basis of this results that we compute the CN(curve number) using GIS after classify the map of soil and landuse on the Su-Young River basin. Also, as determination a classified cell size of
in case of the most optimum size.
A Study on the Methodologies for Resolving Cadastral Non-Coincidence
Jung, Young-Dong ; Choi, Han-Young ;
Journal of Korean Society for Geospatial Information System, volume 11, issue 3, 2003, Pages 55~63
Korean cadastral system is primarily based on the graphical maps, thus, map reproduction by excessive shrinkage or extension, map mishandling and imperfection of surveying techniques have created cadastral non-coincident areas, which caused public distrust as well as considerable difficulties in land administration and policy making. Therefore, in this study, the methodologies for the resolution of the non-coincident problem are presented by means of a comparative analysis between cases of the non-coincident areas. The non-coincidence caused by the mismatch of parcel boundaries can be settled by introducing a coordinate-based system namely
Integrated Land Information System
, meanwhile, those by other reasons can be done by establishing and executing a plan that can deliver the unification of the cadasoal and the land registration systems. Governmental intention and budgetary measures for securing the project expenses are essential to make this feasible. If the comprehensive improvement project is completed, the cadastral registers that define the parcel boundary, area and ownership will recover public confidence, which in turn secures land owners' rights by promoting land markets and stabilizing land prices.
