Georgia 44 Class Landcover, 1998
(click on image to view a larger map)
The mapping of land cover is done by adopting or developing a land cover classification system, delineating areas of relative homogeneity (basic cartographic "objects"), then labeling these areas using categories defined by the classification system. More detailed attributes of the individual areas are added as more information becomes available, and a process of validating both polygon pattern and labels is applied for editing and revising the map. This is done in an iterative fashion, with the results from one step causing re-evaluation of results from another step.

Code Class Name Description
7 Beach Open sand, sandbars, mud, and some sand dunes - natural environments as well as exposed sand from dredging and other activities. Mainly in coastal areas, but also inland, especially along the banks of reservoirs.
9 Coastal Dune Sand dunes and associated vegetation.
11 Open Water Lakes, rivers, ponds, ocean, industrial water, aquaculture.
18 Transportation Roads, railroads, airports, and runways.
20 Utility Swaths Open swaths maintained for transmission lines.
22 Low Intensity Urban - Nonforested Low intensity urban areas with little or no tree canopy.
24 High Intensity Urban Commercial/industrial and multi-family residential areas.
31 Clearcut - Sparse Vegetation Recent clearcuts, sparse vegetation, and other early successional areas.
33 Quarries, Strip Mines Exposed rock and soil from industrial uses, gravel pits, landfills.
34 Rock Outcrop Rock outcrops and mountain tops.
72 Parks, Recreation Cemeteries, playing fields, campus-like institutions, parks, schools.
73 Golf Course Golf courses.
80 Pasture, Hay Pasture, non-tilled grasses.
83 Row Crop Row crops, orchards, vineyards, groves, horticultural businesses.
201 Forested Urban - Deciduous Low intensity urban areas containing mainly deciduous trees.
202 Forested Urban - Evergreen Low intensity urban areas containing mainly evergreen trees.
203 Forested Urban - Mixed Low intensity urban areas containing mixed deciduous and evergreen trees.
410 Mesic Hardwood Mesic forests of lower elevations in the mountain regions (Blue Ridge, Cumerland Plateau, and Ridge and Valley) and upper Piedmont. Includes species such as yellow-poplar, sweetgum, white oak, northern red oak, and American beech.
411 Sub-mesic Hardwood Moderately mesic forests of the mountain regions and upper Piedmont. Includes typical oak-hickory forests. The dominant natural cover class in most mountain areas.
412 Hardwood Forest Mesic to moderately mesic forests of the lower Piedmont and Coastal Plain. Includes non-wetland floodplain forests of yellow-poplar and sweetgum, ravines of oaks and American beech, and many upland oak-hickory stands.
413 Xeric Hardwood Dry hardwood forests found throughout the state, although most common in the mountain regions, and progressively more rare southward. Includes areas dominated by southern red oak, scarlet oak, post oak, and blackjack oak.
414 Deciduous Cove Hardwood Mesic forests of sheltered valleys in the Blue Ridge and Cumberland Plateau at moderate to high elevations. Typically includes northern red oak, basswood, buckeye, and yellow-poplar.
415 Northern Hardwood Restricted to the highest elevations of the Blue Ridge. Dominant tree species may include yellow birch, black cherry, and American beech.
420 Live Oak Forests dominated by live oak. Most common in maritime strands along the Atlantic Coast. Also may occur in strip along southern border into southwest Georgia.
422 Open Loblolly-Shortleaf Pine Only mapped in the Piedmont. Includes older, fairly open stands that may be almost savanna-like in appearance.
423 Xeric Pine Very dry evergreen forests restricted to the mountain regions and upper Piedmont. Includes Virginia, shortleaf, pitch, and table mountain pines.
424 Hemlock-White Pine Mesic evergreen forests frequently associated with riparian areas. Restricted to Blue Ridge and Cumberland Plateau.
425 White Pine Moderately mesic evergreen forests of the Blue Ridge, usually dominated by white pine.
431 Montane Mixed Pine-Hardwood Moderately mesic mixed forests of the Blue Ridge. Typical species include white pine, white oak, hickories, and yellow-poplar.
432 Xeric Mixed Pine-Hardwood Dry mixed forests found throughout the state, although most common in the mountain regions, and progressively more rare southward. Includes areas dominated by a mix of pines (most frequently shortleaf or Virginia in the mountains, and shortleaf or longleaf elsewhere) and hardwood species such as southern red oak, scarlet oak, post oak, and blackjack oak.
433 Mixed Cove Forest Mesic mixed forests of sheltered valleys and riparian areas in the Blue Ridge and Cumberland Plateau at moderate to high elevations. Typically includes eastern hemlock, yellow-poplar, and black birch.
434 Mixed Pine-Hardwood Mesic to moderately dry forests of mixed deciduous and evergreen species found throughout the state at lower elevations. May include areas dominated by sweetgum, yellow-poplar, various oak species, and loblolly or shortleaf pine.
440 Loblolly-Shortleaf Pine Found from the upper Coastal Plain northward (rare in the Blue Ridge except at the lowest elevations). Includes many stands heavily managed for silviculture as well as areas regenerating from old field conditions.
441 Loblolly-Slash Pine Found on the lower Coastal Plain. Includes many heavily managed stands as well as a few natural areas.
511 Shrub Bald Restricted to mountain tops at high elevations of the Blue Ridge. May be dominated by mountain laurel, rhododendron, or blueberry.
512 Sandhill Areas of scrub vegetation on deep, sandy soils on the Coastal Plain, especially near the Fall Line and along larger streams. May be dominated by turkey oak, blackjack oak, live oak, holly, and longleaf pine.
513 Coastal Scrub Thickets between coastal dunes, typically dominated by wax myrtle. Sometimes found adjacent to saltmarsh areas.
620 Longleaf Pine Open, savanna-type stands. Heavily managed plantations would likely be classed with 440 or 441. Most common on the lower Coastal Plain, although found up to the lower Piedmont and historically in the Ridge and Valley.
890 Cypress-Gum Swamp Regularly flooded swamp forests mainly found on the Coastal Plain. May include either riparian or depressional wetlands. Usually dominated by pond or baldcypress and/or tupelo gum.
900 Bottomland Hardwood Less frequently flooded wetland forests found throughout the state, but most common on the Coastal Plain. To the north, may be dominated by sweetgum, elms, and red maple. To the south, wetland oaks (water oak, willow oak, overcup oak, swamp chestnut oak), black gum, and even spruce pine become more common.
920 Saltmarsh Emergent brackish or saltwater wetlands dominated by Spartina or Juncus.
930 Freshwater Marsh Emergent freshwater wetlands found throughout the state. May be dominated by grasses or sedges.
980 Shrub Wetland Closed canopy, low stature woody wetland. Found throughout the state, although most common on the Coastal Plain. May be result of clearcutting of wetland forests. Frequently includes willows, alders, and red maple.
990 Evergreen Forested Wetland Restricted to the Coastal Plain. Includes forests dominated by bay species, wet pine forests (typically slash or pond pine), or Atlantic white cedar.
