Mississippi Hydrography Dataset Development (MDEM Layer Development)
Mississippi Department of Environmental Quality
Hydrography is one of the seven framework data layers of the Mississippi Digital Earth Model (MDEM) and is a high priority for USGS at the Federal level. Since completing an initial pilot project with MDEQ and USGS in 2010, Waggoner has completed
the mapping of 25,000 square miles of the Mississippi Hydrography Dataset, consisting of local resolution hydrography data throughout the state at the HUC-8 basin level.
