Hello, I'll try to change many raster images into geotiffs using gdal (gdalwarp). And, want to know where each image's non -gcp pixel points will move to.
For example, If image's point (300,400) will move to GeoTiff's (135e,35n), by using gcps (200,300 => 130e,40n), (200,500 => 130e, 30n), and (400, 300 => 140e, 40n), I want to know this change (300,400 => 135e,35n). And also, (250, 400) moves where? (350, 200) is? and so on. Is there any function to get this value? Or, I also understand program a little, it is OK if it needs some coding. Thanks, Ko-hei _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
