Color Aerial PhotosYou will be able to view low altitude, color aerial photos for all states except Alaska, Hawaii and New Mexico. You can also view and print perfectly matched map / aerial photo pairs. To change from topographic maps to aerial photos simply click your viewing format in the "Base Map" window. The view will change from map to photo and remain fixed upon your location. Lots of topographic map users find that aerial photos instantly improve their navigation ability - photos have LOTS of information that is not shown on any map. Compile a personal library of maps and photos for all of the places that you work or enjoy the outdoors. To print a matched pair (aerial photo / topographic map) simply print the photo then click "Topo Maps" in the Base Map setting box and print the map. How old are the photos and maps? You can find the revision date f or a topo map or the photo date of an aerial by clicking on the "More about this map" link under the map window. This will report the photography date and map revision date for the center of the map window. Most aerial photos are 1990s or newer. Updated photos are added quarterly.

Black & White Aerial PhotosYou will also have access to black and white aerial photos. Aerial photography, precisely matched to the maps, is the most important advantage that MapPass offers over most mapping software. Why use aerial photos? If you use USGS topographic maps without aerial photographs then you are in the field with only 1/2 of the tools. How many times you have looked at a map and wished for more information? Photographs show vegetation, fence lines, roads, trails, structures and terrain features that do not appear on maps. MapPass allows you to view color or black & white photos at seven different zoom levels - from a regional view at 1:5,000,000 down to a highly detailed 1:3,000.
