Mississippi Digital Earth Model Hydrography Dataset Development

Mississippi Department of Environmental Quality
Statewide, Mississippi

In 2003, the Mississippi Legislature passed House Bill 861 to establish the Mississippi Coordinating Council for Remote Sensing and Geographic Information Systems. The Mississippi Department of Environmental Quality (MDEQ) oversees the development, management and implementation of the Mississippi Digital Earth Model (MDEM), an initiative to create an up-to-date, computerized map of Mississippi. The MDEM consists of the seven core data layers that are standard components of electronic maps used everywhere by the geographic information system (GIS) community.

Hydrography is one of the seven core data layers of the MDEM. Beginning with an initial pilot project with MDEQ and the US Geological Survey (USGS) in 2010, Waggoner (as part of Mississippi Geographic Information, LLC) mapped in two dimensions all 48,000 square miles of Mississippi’s Hydrography Dataset, providing local resolution hydrography data at the HUC-8 basin level to MDEQ. Waggoner is honored to support the work of MDEQ and USGS on this important dataset for Mississippi and the nation.

Project Data

MDEQ coordinates the MDEM with the USGS National Map. From 2010 through 2023, Waggoner developed 2D hydrography data to USGS National Hydrography Dataset standards for all 48,000 square miles of the state of Mississippi.

In 2023, USGS standards were updated to 3D data, and Waggoner will begin mapping in three dimensions as part of a new project.
