This data set represents a revised version of that map and was created using multi-temporal PALSAR data and Landsat images from 2016-2017. In addition to Phragmites distribution, the data sets shows several land cover types including urban, agriculture, forest, shrub, emergent wetland, forested wetland, and some based on the dominant plant species (e.g., Schoenoplectus, Typha). The classified map was validated using over 400 field visits.This map covers the Green Bay peninsula and surrounding area on Lake Michigan. This map is an update of a previous circa 2010 map to help monitor invasive species and anthropogenic changes in the Great Lakes region. This work builds on a previous project, (Bourgeau-Chavez, et al., 2015 Development of a Bi-National Great Lakes Coastal Wetland and Land Use Map Using Three-Season PALSAR and Landsat Imagery. Remote sensing. doi: 10.3390/rs70708655), and uses the same methods as described in noted citation. Maps are expansions of previously mapped areas to monitor land cover changes, specifically changes in invasive phragmites caused by drivers such as treatments and water level changes. 20150414 20171030 publication date Complete None planned -88.5198 -86.6113 45.9717 43.9413 ISO 19115 Topic Category imageryBaseMapsEarthCover Marine Realms Information Bank (MRIB) keywords wetlands USGS Thesaurus invasive species land use and land cover USGS Metadata Identifier USGS:5d0ce918e4b0941bde51dc97 Common geographic areas Lake Michigan Wisconsin Green Bay None.

Photographs of each field site were cross checked by analysts to verify cover type and classification accuracy. This information was used to validate map products generated with a machine learning algorithm. Confusion matrices are provided as excel documents. Analysts conducted visual inspections of the classified maps to ensure consistency. Data values falling outside of expected ranges were inspected and corrected. Each 12.5 square meter pixel is assigned a land cover type. Land cover types were derived from Anderson level II (1976) and augmented with wetland classes common in the Great Lakes region.The minimum mapping unit for the data products is .2 hectares due to the spatial resolution of the satellite remote sensing data used to derive the maps. Study regions were selected based on known infestations of Phragmites and satellite data availability. Phragmites occurrence is not limited to the mapped study regions.
