Purpose: These data were compiled to provide the Alabama Department of Conservation of Natural Resources with historical submerged vegetation polygons. This theme was created for coastal management purposes in partial fulfillment of a grant from the Alabama Department of Conservation and Natural Resources State Lands Division, Grant #GSA-CZM-308-08-2. Funding for this project was provided by the Alabama Department of Conservation and Natural Resources, State Lands Division, Coastal Section (ADCNR-Coastal), in part, by a grant from the National Oceanic and Atmospheric Administration, Office of Ocean and Coastal Resource Management, Award No. NA04NOS4191091.

Use_Constraints: Data should not be used at a scale larger than 1:100,000. Reproduction or redistribution of digital data sets or products derived therefrom to a third party organization or entity is expressly forbidden. None of these data shall be electronically duplicated on magnetic or optical media for use by others, in whole or in part, without permission of the Geological Survey of Alabama. Any hardcopies utilizing these datasets shall clearly indicate their source. If the user has modified the data in any way, user is obligated to describe the types of modifications performed on the hardcopy map. User specifically agrees not to misrepresent these datasets, nor to imply that changes made were approved by the Geological Survey of Alabama (GSA). The GSA should be acknowledged as the originator of the data. This dataset is to be used as a primary reference source. This is public information and may be interpreted by organizations, agencies, units of government, or others based on needs; however, they are responsible for the appropriate application. Federal, State, or local regulatory bodies are not to reassign to the originators any authority for the decisions they make. Photographic or digital enlargement of these maps to scales greater than that at which they were originally delineated can cause misrepresentation of the data. If enlarged, the maps will not include the fine detail that would be appropriate for mapping at the large scale. Digital data files are periodically updated. Files are dated, and user is responsible for obtaining the latest version of the data.
