The USGS UMESC is using state-of-the-art three-dimensional mapping technologies to create vegetation maps and mapping products from high-resolution digital aerial photography for national wildlife refuges within the 11-state USFWS Midwest Regional (Region 3). During FY13–14, in addition to refuge-managed lands on the Upper Mississippi River floodplain that were mapped for another project, vegetation products were delivered for several Region 3 Refuges including Port Louisa (Iowa) and Ottawa (Ohio). These projects used color infrared analog and digital aerial photography and, where available, lidar.
