Aerial photos complement other types of maps because they give you a snapshot of reality. Programs that display aerials (map-speak shorthand for aerial photos) are both inexpensive and easy to use. In this chapter, I review mapping programs that can exploit aerial photos, primarily focusing on the popular shareware application, USAPhotoMaps. To better illustrate the capabilities and functions of this program, I walk you through downloading an aerial photo, scrolling and zooming, interfacing the program with a GPS receiver, and saving map data. To get the most from this blog section, download and install USAPhotoMaps (http://jdmcox.com) and then use the program to work through the examples in the following pages. Unlike some shareware programs, USAPhotoMaps isn’t crippled; that is, all its features work when you download the program. If you find the program useful, you can make a donation to the author’s PayPal account.
