Hi again,
Thanks for your detailed reply, EinBerliner. I appreciate your help. I've stitched the images together to reduce the amount of work involved in georeferencing them (around 1200 pictures for each of the 19 passes made by the airplane)- now I merely need to georeference 19 images, instead of a bazillion.
I do have ArcGis 10. Based on your information, my process is now whittled down to:
1. Georeference each of the 19 photos (either manually or automatically).
2. Use ArcGis to orthorectify either each of the photos or the mosaic of the photos.
3. Export to jpeg/tiff.
I have photos shot from a thermal camera. I also have a file of the camera coefficients at each stage/pass- will this help in the georeferencing and orthorectification process? If so, could you tell me how? Is there perhaps some way to automatically georeference these using the camera coefficients that I have (this information isn't embedded into the photos, as far as I know, but I do have the information handy). I have some high level GPS information of the whole plot as well.
I'd appreciate your help, hopefully for one last time!
Thanks!
