An Experimental Study on the Generation of Thematic Maps Using Kompsat-2 Image Data

The mapping with the high resolution satellite image instead of aerial images is one of the most important applications in the field of remote sensing. The purpose of this study is to investigate the possibility for generating the thematic maps such as digital map, ortho-rectified image, and Digital Elevation Model (DEM) using the second KOrea Multi-Purpose SATellite (KOMPSAT-2) stereo dataset. In conclusion, the preliminary experimental results are acceptable for generating the digital map of 1/5,000 scale based on the mapping regulation in Korea. The mapping accuracy of the horizontal and vertical direction was verified using GPS survey data. However, by interpretative measures, it is very difficult to extract all layers which are needed to generate the digital map of 1/5,000 scale. The accuracy of an ortho-rectified image and DEM, which both are generated from the KOMPSAT-2 stereo dataset, was also acceptable. This study verified that KOMPSAT-2 stereo dataset is useful to generate the thematic maps and related applications.
