A lot of people use our GIS mapping to look for land use changes through time. The BrownDog interactive GIS map has a handy tool for this called the "Swipe" tool.
Follow the steps on the illustration below to learn how to use the 'swipe' tool. This example shows you how to compare the May 2014 aerial image to the Summer 1960 photo, but of course, you could choose to compare any of our aerial images.
P.S. This reminds me of Dora the Explorer, a TV show my kids used to watch. Some of you might think of this too: "If there's a place you gotta go, I'm the one you need to know. I'm the Map!" and of course, "Swiper, no swiping!"
