Historical Submerged Aquatic Vegetation (SAV) Distributions from Coastal Alabama, Gulf of Mexico from 1940-01-01 to 1966-10-21 (NCEI Accession 0162477)
Listed in NASA Earthdata CMR
Historic black and white aerial photographs of coastal Alabama (Mobile Bay and adjacent waters) from 1940, 1955, and 1966 were digitized and georeferenced using Blue Marble Geographic Transformer version 5.1.
Description
Outlines of distinguishable submerged aquatic vegetation (SAV) signatures in the aerial photography were digitized in a GIS environment, supplemented by visual examination of the photographic prints. ESRI polygon coverage of SAV beds was created in ArcView version 3.2.
