Description: This data set a GIS-based landscape (Level one) assessment of the water quality and habitat benefits of non-tidal contractor delineated wetlands in Virginia utilizing land cover from five years (2001, 2006, 2011, 2016, and 2019). The model assessment uses remote sensing and GIS technology to characterize land use patterns and features around wetlands such as surrounding land cover and density of roads as well as individual wetland characteristics such as wetland size to determine the wetlands overall condition as related to habitat and water quality functions. The water quality analysis determines the percentages of different land covers and features within the contributing drainage area of the wetland.

Description: This data set a GIS-based landscape (Level one) assessment of the water quality and habitat benefits of non-tidal contractor delineated wetlands in Virginia utilizing land cover from three years (2001, 2006, 2011, and 2016). The model assessment uses remote sensing and GIS technology to characterize land use patterns and features around wetlands such as surrounding land cover and density of roads as well as individual wetland characteristics such as wetland size and type to determine the wetlands overall condition as related to habitat and water quality functions. The water quality analysis determines the percentages of different land covers and features within the contributing drainage area of the wetland.
