These raster files showing wetland areas that were functional during Rainwater Basin Wetland Complex Annual Habitat Survey. Annual Habitat Surveys (AHS) identify areas of wetland ponding and function (ponding and potential hydrophyte vegetation) during spring migration. The information is developed by Rainwater Basin Joint Venture to identifying how much habitat the Rainwater Basin Wetland Complex provides to migratory waterfowl on an annual basis. AHS have been completed for 2004 and 2006-2020 where high-resolution aerial photos of the Rainwater Basin Wetland Complex are classified using an image object classification software to determine land cover (hydrophyte water, agriculture water, hydrophytes, agriculture, or trees) and whether those land covers ponded water during image acquisition.
