Created as a base for future projections. A combination of three high-res impervious classes (impervious roads, impervious non-roads, and tree canopy over impervious), resampled to 30-meter resolution, and burned into the 2011 NLCD (2014 edition). Technically, a hybrid land use/cover datasets because agriculture is a land use and imperviousness is land cover. The 2013 projection base represents 2013 imperviousness and 2011 classes for other land cover/use classes. Allows visualization of change between the baseline and future projections. |
