Batch Georeferencing

VictorGensini — Thu, 17 Jun 2010 02:19:24 GMT

Help!

I have nearly 5,000 raster images that are all of the same size and need to be georeferenced to the same location. I have created a link table .txt file that has the according transformation. Is there any way to automate this process (i.e. georeferencing and rectifying) so that I need not click on each layer and georeference separately? I'm familiar with Model Builder, but there is no "georeference" tool. Any help or ideas would be greatly appreciated. Not a great programmer, so if you have any code ideas, please be thorough. Thanks!

Once you have used Update Georeferencing on one of your rasters, you might be able to copy the world file (I've had few enough of them that I didn't need a script or batch copier but you can Google on "copy files multiple times" or something like that) and then use a batch file renamer to rename them to match up with your raster's names. But if your rasters have complex names this may not work too well. Unless you really need to rectify them I'd skip that process since it takes awhile to write the new raster, you may find it's image quality reduced or you may have to switch raster formats such as when using sids.

Johns:

Thanks for the tip, but I'm pretty sure I don't have any "word document" anywhere. I forgot to mention that the raster images are saved in GRID format.

He said World file not word file. A world file show up in the.jgw extension after georeferencing if a jpeg. TFW I think for tiffs. GRIDS I believe show up with a w after the raster name.
