Groundwater Inventory and Mapping Project, a cooperative effort between the Water Bureau - Michigan Department of Environmental Quality, USGS - Michigan Water Science Center and Michigan State University - Institute of Water Research, RS&GIS and Biosystems and Agricultural Engineering. This project was mandated by P.A. 148 (Michigan Acts of 2003). Major funding was provided by MDEQ, supplemented with additional funds from the USGS Cooperative Water Program. Michigan State University: Remote Sensing & GIS Research and Outreach Services - Department of Geography, David P. Lusch, Ph.D. Using GIS overlay techniques, surface formations extracted from the Quaternary geology map were combined with soil texture groups that had been reclassified from the STATSGO data, based on the Michigan Soil Management Group protocol. The concatenated surface formations and generalized soil texture categories were grouped into glacial landsystems.
