Delineation

The limit of SWAMP/MARSH is the extent of the wet, spongy area.

 

Data Extraction

Capture Conditions

 

If SWAMP/MARSH is ≥ 0.1" along the shortest axis,then capture.

 

Source Interpretation Guidelines

 

All

 

Break SWAMP/MARSH for RAILWAYS and for Class 1 and Class 2 ROADS.

 

Break SWAMP/MARSH for clearings that are ≥ 0.05" along the shortest axis, or for

linear clearings that are ≥ 0.025" along the shortest axis.

 

Do not capture mangrove areas as SWAMP/MARSH, see TREES (Vegetative

Surface Cover theme).

 

SWAMP/MARSH may be coincident with AREA OF COMPLEX CHANNELS, ESTUARY, LAKE/POND, SEA/OCEAN, STREAM/RIVER.  An alternate approach is to use hydrographic category to describe the water regime of the SWAMP/MARSH.
