资源简介：
Vegetation maps and descriptions of plant associations were compiled for 16 (15) barrier and marsh islands on the seaward margin of the Delmarva Peninsula (USA) based on 1:20,000 scale false-color infrared aerial photography taken on June 4, 1974 and subsequent extensive ground-truthing. Twenty-six mapping units based on botanical, topographic, and edaphic characteristics representative of distinct plant associations, ecotones, or non-vegetated surfaces were identified. Published maps were later digitized and georeferenced for use with GIS systems. Chimney Pole Marsh, for which only the inlet-facing shoreline was originally mapped, rather than the whole island, was never digitized and is not included in this dataset.
