Impervious Surfaces Change 2003-2011
This is a statewide, seamless digital raster dataset of the impervious surfaces for the State of Rhode Island derived using semi-automated methods and based on imagery captured in spring 2011. The project area encompasses the State of Rhode Island and also extends 1/2 mile into the neighboring states of Connecticut and Massachusetts. Geographic feature accuracy meets the National Mapping Standards for 1:5000 scale mapping with respect to base level data (roads, hydrography, and orthos). This raster dataset has three classes - No Change, Impervious Added, Impervious Removed. impervious. Impervious surfaces are human-created surfaces that do not allow water to permeate through them. The dataset has a spatial resolution of 2 ft.The Value field holds each pixel's Impervious Surface Classification, 1 = No Change, 2 = Impervious Added, 3 = Impervious Removed
