Lower Mississippi River and Floodplain Extent Circa 1899 Map of the alluvial valley of the Mississippi River from the head of St. Francis Basin to the Gulf of Mexico, showing lands subject to overflow, location of levees and trans-alluvial profiles Downloaded from: https://www.digitalcommonwealth.org/search/commonwealth:7h14b0450 Edited (to correct position of panels) and georeferenced by Yvonne Allen (USFWS) to geographic NAD1927 using ArcGIS , 3rd order polynomial and 80 ground control points using lat lon grid. ALBERS PROJECTION Categories: Data, Map; Types: GeoTIFF; Tags: Lower Mississippi River Poplar Island Digitizing In order to allow for a comparison across years we visually digitized landcover of Poplar Island from a single image per year at a 1:1000 spatial extent with a minimum mapping unit of 300 square meters (no minimum dimensions aside from area). Images used to assign landcover were provided by the U.S. Army Corps of Engineers and were captured between July and October of their respective years. All images were 1 foot resolution.

We derived these rasters by calculating the average conductivity for each map unit in combined surficial-bedrock geologic maps. We used state geologic maps (Preliminary Integrated Geologic Map Databases for the United States, Open File Reports 2004-1355, 2005-1305, 2005-1323, 2005-1324, 2005-1325, 2005-1351, and 2006-1272), which depict surficial geology instead of bedrock when the surficial layers are sufficiently deep. For the state maps that do not incorporate surficial geology (i.e., midwestern states), we overlaid surficial geologic map units with thicknesses greater...
