Are the data layers available in digital format?
Yes. The images are available in TIF or MrSID format. TIFs can be viewed using any image viewing software such as Internet Explorer or Netscape. MrSID images or TIFs are mainly used in GIS or CAD software designed to view the images. Any user who has AutoCAD 2002 or later version can use the MrSID images. We most commonly provide the images in TIF format because people seem to be more familiar with that data format.
