Hi. Does anyone know of a relatively quick method of joining together color ortho photo tiles to create 1 huge image. I need to join about 2000 tiles into one image.
The individual images are 5000 rows x 5000 columns, and they are all already in the same projection. Is there any software available (free or not) that can do this quickly (i.e. less that 1 week?) I have tried r.patch and mapcalc in grass, but that seems way too slow. I heard something about gdal_merge.py. Has anyone tried this? BTW - I would like to preserve the projection in the final image and be able to import it into grass.
thanks,
Lisa Stillwell
There is a software called ER Mapper....you can download it..
I think it´s the quickest way to put your Orthophotos together...it´s really quick.....

I use gdal <http://gdal.org/> for that. It is most convenient 
Depending on the output format (you might want to use JP2k, or ECW),
it's as simple as
gdal_translate file1.tif file2.tif output.tif
There are plenty of options, but the basics are just that.
Good luck
