The United States Geological Survey, the agency responsible for charting the nation's topographic ups and downs, debuted a new online tool that allows users to pull up maps through the ages for different geographic locations and layer them for a neat compare-and-contrast effect. The easy-to-use feature lets you search by location, click a point, and see what maps are available for the area. You can then overlay them and adjust the transparencies to see change over time, especially when it comes to urbanization. You can also download the full-size files of the old maps, in case you need a super cool new desktop wallpaper.

Shirika la Marekani la Utafiti wa Jiolojia (USGS) limetangaza kuwa limetengeneza chombo kipya cha mtandaoni ambacho kinawawezesha watu kuchunguza ramani za maeneo mbalimbali na kuibadilisha. Kipengele hicho rahisi kutumia kinakuwezesha kutafuta kulingana na mahali ulipo, kubonyeza sehemu fulani, na kuona ramani zinazopatikana kwa ajili ya eneo hilo. Unaweza kisha overlay yao na kurekebisha uwazi kuona mabadiliko kwa muda, hasa linapokuja suala la mijini. Unaweza pia kupakua faili za ukubwa kamili za ramani za zamani, ikiwa unahitaji karatasi ya ukuta mpya ya desktop.
