Residential (11)

From Anderson et al. (1976):
Residential land uses range from high density, represented by the multiple-unit structures of urban cores, to low density, where houses are on lots of more than an acre, on the periphery of urban expansion. Linear residential developments along transportation routes extending outward from urban areas should be included as residential appendages to urban centers, but care must be taken to distinguish them from commercial strips in the same locality. The residential strips generally have a uniform size and spacing of structures, linear driveways, and lawn areas; the commercial strips are more likely to have buildings of different sizes and spacing, large driveways, and parking areas. Residential development along shorelines is also linear and sometimes extends back only one residential parcel from the shoreline to the first road.

The VMP orthophotos and NAIP imagery are both suitable for identification of residential areas. Housing and other structures generally appear as small white rectangular areas that stand out amongst the surrounding terrain in the VMP orthophotos, however some structures may appear very dark and will only be distinguishable by the surrounding lot or ancillary datasets. Residential areas include the surrounding developed land, structures, and private roads or driveways. The presence of lawns or forest clearings in rural areas might indicate the location of a residence. Some high density residential areas are digitized into a block that contains the entire area of developed land.
