Long Island Sound Changing Landscape is a remote sensing-based land cover study that charts landscape changes in Connecticut and portions of New York. It covers the 30-year period from 1985 to 2015 (with in-between dates of 1990, 1995, 2002, 2006, 2010 and 2015).
The newest set of land cover has been added to the Changing Landscape study which includes a 2015 date and some minor modifications to earlier dates. All dates are available for download. The download files are zipped img rasters with 12 classes.
