NLCD Land Cover by Block Group
How much of each neighbourhood-sized area of Massachusetts is developed, farmed, forested, wetland or water, and how much of it is paved or roofed, for every year since 1985, added up from the U.S. Geological Survey's 30-metre satellite land cover map. Use it to follow development and the loss of farmland or forest across counties, cities and townships over four decades, to compare places by how built-up they are, and to map land cover as a choropleth.

Annual NLCD uses a modernized, integrated approach to map, monitor, synthesize, and understand the complexities of land use, cover, and condition change.
