I have been trying to orthorectify quick bird and worldview images using the supplied RPB file and my own DEm. The result i'm getting is an image exactly aligned with the original one but some 30km above(far from correct location) . tried it for almost 10 images, getting same results. Any idea colleagues what might cause this.

Hi all, please assist with orthorectification. Is it possible to orthorectify images without the rational polynomial coefficients (RPC). I have satellite images and they only have .aux , .rrd & .tiff files. Been trying to rectify with erdas but they are not getting rectified properly onto the reference image. Is there any technique i can use . Thank you.
