 "description": "High-resolution wetlands dataset for Pennsylvlania. Primary wetlands classes were mapped, plus water:EmergentScrub\\ShrubForestedWaterThe primary sources used to derive this modeled wetlands layer were 2006-2008 leaf-off LiDAR data, 2005-2008 leaf-off orthoimagery, 2013 high-resolution land-cover data, and moderate-resolution predictive wetlands maps incorporating topography, hydrological flow potential, and climate data. This dataset is considered current based on the 2013 land-cover map.Wetlands classes were mapped using a rule-based expert system embedded within an object-based framework. Object-based image analysis techniques (OBIA) work by grouping pixels into meaningful objects based on their spectral and spatial properties. Using this technique, a rule-based expert system was designed to effectively mimic the process of manual image analysis by incorporating the elements of image interpretation (color/tone, texture, pattern, location, size, and shape) into the classification process. A series of morphological procedures were used to ensure that the end product was both accurate and cartographically coherent.This dataset was developed to support land-cover mapping and modeling initiatives in Pennsylvania.",

 "accessInformation": "This wetlands dataset was developed by the University of Vermont Spatial Analysis Laboratory in collaboration with Patrick Raney of Ducks Unlimited.  Funding was provided by the U.S. Environmental Protection Agency through a grant with the Pennsylvania Department of Environmental Protection and the Western Pennsylvania Conservancy.  An earlier project focusing on the Chesapeake Bay Watershed portion of Pennsylvania was funded by the National Park Service and the U.S. Environmental Protection Agency under a collaborative grant with the Chesapeake Bay Conservancy.",
