High resolution images data from Terrasar-X are used to extract digital elevation model (DEM) using stereo radargrammetry in the attempt achieve better of terrain surface Indonesia. As sample this study, pairs TerraSAR-X StripMap mode (~3m resolution) on Madiun city is with difference incidence angle around ~18.88 degree area. Furthermore, field observation selected area will be accuracy assessment. The (DSM) generated by study shows us high spatial pixel spacing 5.57 meter and ~4 meter.
