I have a .tiff image that I am trying to overlay in google earth. For that I require to georeference it first. The image projection is UTM with NAD83 as datum. I know the lat/long of the four corners of the image.
I am doing the following way:
- gdalinfo to get the four coordinates.
- gdal_translate to specify lat/long info
- gdal2tiles.py to tile the image.
The only thing is bugging me is that I never specified UTM and NAD83, then how come it can overlay my image? Does anybody know how to specify this projection information?
