This base dataset is a combination of three globally available datasets creating a new dataset is that is inclusive of both finer-resolution data while accounting for a wide range of wetland sizes. The three source datasets are: 1) CW-WTD 500 m dataset resampled to 30 m. – Wetland dataset built from a composite wetland-water table depth (Tootchi 2019), 2) CCI (Climate Change Initiative) data resampled from 300 m to 30 m - CCI defined wetlands as “…mixed classes of flooded areas with tree covers, shrubs, or herbaceous covers plus inland water bodies” and 3) Global Surface Water (GSW) 30-m (Pekel et al. 2016) – A pixel was considered a wetland if it had at least one inundation event over a 32-year range. Global Wetland data provides a series of raster datasets that depict wetlands at a global scale. Each raster represents a single hydrobasin. The goal of this product is to provide a seamless global coverage of wetlands. The United States Environmental Protection Agency through its Office of Research and Development partially funded and collaborated in the development of this dataset under contract EP-C-15-010/68HERC20D0029 to Pegasus Technical Services. This dataset has been subjected to Agency review and approved for publication, but does not necessarily reflect the views and policies of the United States Environmental Protection Agency.
