Is there a non-graphical command for georeferencing an imported jpeg or tiff image? For my own use, I can use i.target and i.points and all that jazz to do it from the Grass GUI; however, I don't want the users of my application to go out to Grass because they are unfamiliar with it and will undoubtedly get confused and take their frustration out on me. So is there a way I could simply pass Grass the GCPs from the image with matching coordinates via the command line?
Thanks,
David
David,
I.rectify rectifies images without a graphic interface. It just needs a
points file with GCP's in it. I.points uses a graphic interface to generate
the points file of GCP's from an already rectified map. However, if you
generate them in another way, it is not necessary.
Also, the GDAL utility gdalwarp can rectify and georeference an image. It
can use GCP's embedded in the image file (e.g. Terra ASTER HDF files) or an
external GCP file.
