Viewing instructions

No special viewers are needed to view the digitized maps in this collection. Your Internet browser automatically shows the digitized maps, allowing you to zoom in and out of the areas that you wish to examine. This view also allows saving and copying of map images, using the right-click menu.

Please note that the maps on this site may take some time to load, depending on both the speed of your computer and your Internet connection.

For users who may wish to pan, rotate, print and save images, we offer two other methods of viewing the map images: with JAVA, and with the MrSID Plug-in.
