Georeference TIF images

[yekom]

Hello. I have some aerial images in TIF file (likely "orthorectified") but are completely unscaled. What I do to use them is to take a length measurement in the field from two recognizable features and then scale them in Autocad. I can also assign true coordinates to some features on the map after scaling. The thing is that I want to export this scaled+georeferenced TIF image from Autocad as a georeferenced TIFF image file, NOT as a .dwg file.

 

Is there a way this can be done?

With Raster Design you can save as a georef tiff. Or you might want to take a look at creating a world file for the tiff image, a simple text file with the insertion point, scale and rotation listed in it. http://wiki.gis.com/wiki/index.php/World_file

Thank you so much for your input! In case anyone's looking for it:

Simple and effective lisp routine for this. This should be combined with another lisp routine to scale the photo using this:

This is a nice add on to georeferenced images, just place image and run the lisp

 

rescale image.lsp.

 

I think we both posted at same time.
