My colleague and I are georeferencing a bunch of .tif images. After each image, we'll click "update georeferencing". The resultant .tif files are different between our computers and I'm trying to learn why.
If I use my colleague's computer to georeference the file, I can keep the georeferenced .tif and delete the .tfwx, tif.aux.xml, and .tif.ovr files, and the .tif will still appear in the correct location. ArcGIS recognizes the correct projection. But if I georeference the file on my computer and delete the .tfwx etc. files, the georeferencing information from my file is completely lost and it does not appear in the correct location. The coordinate system information is lost on my .tif file.
I'm flabbergasted about why our computers are performing this task differently. I've followed the exact same steps on the exact same files on both computers. Can you offer any advice? We're both using ArcGIS 10.
I've run gdalinfo on the various geotiffs, and the results look identical between the two resultant .tif files (right two panels). See gdalinfo results here - https://dl.dropbox.com/u/17669584/error%20messages/stav_vs_matt_computer.JPG.
