The contents are in *.tiff and *.bmp format, aimed at best quality results for your renders. It's best used with Vue or Terragen but can also be used with any other sophisticated 3d package that's out there and able to work with heightmaps.
This pack is free to use for personal and commercial projects. Please check the included readme file for details on that and more specific details on the contents.
