Implementation of a SAR image mapping module using the OGC grid coverage

In the view of geometry, a SAR image is very different from the general optical image by the radar sensor and unique geometric characteristics. So, to combine or analyze with the other image, it must correct the slant range images into the geo-referenced images. This paper describes the SAR geocoding module, which is the sub-module of an IRIHS (Integrated RS s/w for High resolution satellite ImageS): package of "Development of High Resolution Satellite Image Processing Technique" project in Electronics and Telecommunications Research Institute (ETRI). In this paper, we briefly describe the algorithm that is adopted to the functions, and component architecture
