Michigan Groundwater Management Project selects ER Mapper and ECW

Michigan State University (MSU) Remote Sensing & Geographic Information Science Research and Outreach Services (RS&GIS) is completing a groundwater management project.

One part of the study involves the creation of county mosaics from a statewide set of USGS Digital Orthophoto Quarter Quad (DOQQ) images of Michigan using ER Mapper. ER Mapper creates mosaicked ECW image files that are loaded into ESRI’s ArcSDEâ as an embedded raster catalog and accessed using ESRI’s ArcIMSâ. This aerial imagery serves as a backdrop for statewide basemap features from the Michigan Geographic Framework and water well data from the Michigan Department of Environmental Quality.

Other projects at RS&GIS that use backdrops produced with ER Mapper include an online GIS viewer to assist water well drillers in Michigan and an online viewer for the City of East Lansing.
