Hi All, I have a raster image of 2200x1000 pixels. I know three bits of information about the geoposition of the raster: 1. The upper left hand corner's lat and long of the image. 2. The pixel size in meters. The pixels are square 3. The rotation of the image relative to the upper left hand corner position, a bearing if you will.
The documentation on GDAL recommends using setGeoTranform() to correctly position images from pixel space to world space. However, it uses an affine transformation and thus (I believe) implicitly assumes square pixels in the world space. My world space is wgs84, lat and long. Therefore, the output grid is not square, even locally. My question is this: is my assumption wrong that the setGeoTransform function cannot peform the function I desire? If it can, what would the elements of the affine transformation matrix look like? Thanks in advance, Isaac _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
