For #30daymapchallenge #Day21's theme of "Raster", I made this map of Impervious Surface coverage in the Salish Sea Bioregion using data from the Salish Sea Atlas.

You can explore impervious surfaces and other land cover types in more detail in the "Land Cover and Land Use" chapter of the Salish Sea Atlas (https://arcg.is/5nPei).
