Summary	A collection of 1344 topographic map sheets created by the U.S. Army Corps of Engineers from 1894 to 1945 that covers the continental United States, Puerto Rico, the Virgin Islands, and the Panama Canal Area. The maps illustrate tactical and geographic features, such as military bases, landing strips, transportation networks, communication centers, and topography. The maps are labeled in one of three ways: Tactical, Progressive and Strategic. Tactical maps are the most detailed and contain firing grids for artillery. Some of the maps are stamped "restricted" but are no longer classified.
