Tulane Digital Collections: Mapping Louisiana from 1513 - 1900The Louisiana Research Collection's renowned map collection extends from 1513 to the present. With more than 400 maps from before 1799, its holdings include state and regional topographic maps, maps of vegetation zones and natural resources, parish and highway maps, and plans of New Orleans tracing the city's development since its founding in 1718. The maps preserve a variety of information ranging from the names and locations of Indian tribes, land owners, plantations, towns, and fortifications, to explorers' routes, depth soundings for the Mississippi River and coastal waters, state and parish boundaries, crops under cultivation, and even the best spots for fishing.
