Watershed impervious cover relative to stream location

공공데이터포털

Estimates of watershed (12-digit huc) impervious cover and impervious cover near streams and water body shorelines for three dates (2001, 2006, 2011) using NLCD data. Differences between watershed impervious cover and impervious cover near streams can be used to assess the spatial pattern of impervious cover within a watershed. This dataset is associated with the following publication: Wickham , J., A. Neale , M. Mehaffey , T. Jarnagin , and D. Norton. Temporal Trends in Impervious Cover Relative to Stream Location.. JOURNAL OF AMERICAN WATER RESOURCES ASSOCIATION. American Water Resources Association, Middleburg, VA, USA, 52(2): 409-419, (2016).

NLCD 2011 IC reference data

공공데이터포털

Excel files have percentage impervious cover estimates for the Chesapeake Bay region from 30 m 1 m data for six assessment units - 12-digit hydrologic units (watersheds), the riparian zones for the same watersheds, and four square lattices with cell sizes of 40, 2756, 5625, and 22500 ha. There is an excel file for each assessment unit. These data were used to produce the results in Table 2 of the association publication (https://doi.org/10.1016/j.isprsjprs.2018.09.010). This dataset is associated with the following publication: Wickham, J., N. Herold, S.V. Stehman, C.G. Homer, G. Xian, and P. Clagget. Accuracy assessment of NLCD 2011 impervious cover data for the Chesapeake Bay region, USA. ISPRS Journal of Photogrammetry and Remote Sensing.

Percent impervious surface for selected Chesapeake Bay watersheds

공공데이터포털

This dataset contains watershed means of estimated percent impervious surfaces for three time periods: 1992, 2002, and 2012. Estimates are based on coefficients derived from comparing land use of the 2012 NAWQA Wall-to-wall Anthropogenic Land-use Trends (NWALT) product to the 2011 National Land Cover Database (NLCD) imperviousness, then applying those coefficients to previous years (1974-2002) of the NWALT dataset.
