| 1 |
|
Developed |
High-density built-up areas typically associated with commercial, industrial and residential activities and transportation routes. These areas can be expected to contain a significant amount of impervious surfaces, roofs, roads, and other concrete and asphalt surfaces. |
| 2 |
|
Turf
& Grass |
A compound category of undifferentiated maintained grasses associated mostly with developed areas. This class contains cultivated lawns typical of residential neighborhoods, parks, cemeteries, golf courses, turf farms, and other maintained grassy areas. Also includes some agricultural fields due to similar spectral reflectance properties. |
| 3 |
|
Other
Grasses |
Includes non-maintained grassy areas commonly found along transportation routes and other developed areas, and within and surrounding airport properties. Also likely to include forested clear-cut areas, and some abandoned agricultural areas that appear to be undergoing conversion to woody scrub and shrub cover. |
| 4 |
|
Agricultural Field |
Includes areas that are under agricultural uses such as crop production and/or active pasture. Also likely to include some abandoned agricultural areas that have not undergone conversion to woody vegetation. |
| 5 |
|
Deciduous
Forest |
Includes southern New England mixed hardwood forests. Also includes scrub areas characterized by patches of dense woody vegetation. May include isolated low density residential areas. |
| 6 |
|
Coniferous
Forest |
Includes southern New England mixed softwood forests. May include isolated low density residential areas. |
| 7 |
|
Water |
Open water bodies and watercourses with relatively deep water. |
| 8 |
|
Non-forested
Wetland |
Includes areas that predominately are wet throughout most of the year and that have a detectable vegetative cover (therefore not open water). Also includes some small water courses due to spectral characteristics of mixed pixels that include both water and vegetation. |
| 9 |
|
Forested
Wetland |
Includes areas depicted as wetland, but with forested cover. Also includes some small water courses due to spectral characteristics of mixed pixels that include both water and vegetation. |
| 10 |
|
Tidal
Wetland |
Emergent wetlands, wet throughout most of the year, with distinctive marsh vegetation and located in areas influenced by tidal change. |
| 11 |
|
Barren |
Mostly non-agricultural areas free from vegetation, such as sand, sand and gravel operations, bare exposed rock, mines, and quarries. Also includes some urban areas where the composition of construction materials spectrally resembles more natural materials. Also includes some bare soil agricultural fields. |

|
Utility Rights-of-way (Forest) |
Includes utility rights-of-way. This category was manually digitized on-screen from rights-of-way visible in the Landsat satellite imagery. The class was digitized within the deciduous and coniferous categories only. |
