Please be aware that many of the images available are very large and may take some time to download, particularly if you are accessing the Web via a modem.
These files duplicate in digital form the map image that appears on the corresponding printed 1:24,000 scale map. The files are raster images composed of pixels, and are not vectorized for use as intelligent GIS layers. However, they are well suited for use as a backdrop to other GIS layers where they can be positionally registered with vector files and provide additional visual information or be used for on-screen, "heads-up" digitizing, as well as general display and plotting of the map image. The files may be used with a variety of UNIX and PC-based graphics, CAD, and GIS software packages.
If you will be downloading multiple files, check out our Software and Tools page, under "Other Software," for information on a download manager.
