Land cover created with Landsat imagery. Seven dates of land cover are available from each of the following years: 1985, 1990, 1995, 2002, 2006, 2010, 2015.
Note that the map services contain multiple layers. The last layer is the full land cover. The other layers contain on or several classes only.

The Forest Fragmentation map takes the forest land cover classes (including deciduous forest, coniferous forest, forested wetland and utility right of way) and classifies these areas into patch, edge, perforated or core forest. The analysis was only completed for Connecticut. Learn more.

The layer shows impervious surface estimates created by applying coefficients to the land cover classes. The analysis was performed for each date of land cover using HUC 12 watersheds. Learn more.

The riparian area is a 300 foot zone around streams and waterbodies and tidal marsh complexes. The polygon layers includes the waterbodies and tidal marshes where shorelines were buffered. The lines are streams that were buffered on both side. The Riparian Zone shows the resulting riparian area. The land cover was clipped by this area for land cover analysis in the riparian zone.

The riparian area is land closest to water in the form of streams, rivers, lakes and tidal marshes. The riparian land cover shows the land cover types within the riparian zone at that date. Learn more.

The riparian area is land closest to water in the form of streams, rivers, lakes and tidal marshes. The riparian land cover change shows the land cover change between 1985 and 2015 within the riparian zone. Learn more.
The land cover has been summarized by town. The resulting town maps show trends like which towns have more forest than others and which have experienced more change in a specific land cover class.
