image viewer that can decode JPEG and GIF images is needed to display these maps. Most of the images are JPEG images within the 200K to 300K range; however, some of the images are quite large. Many users can have problems with the larger images. This is a result of not having enough memory to view the image; make sure that your web browser is given enough memory.

For large JPEG and GIF map images, the map must be resized to print the entire image (see below). Even after resizing, the quality and legibility of the printed map is dependent upon the quality of your printer. For quickly printing the less detailed maps, you can save the map image file to your hard drive, and then open Microsoft Word. Select Insert from the menu bar, then Picture/File.
