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 those at which they were originally delineated can cause misrepresentation of the data. If enlarged, the data will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the data. Similarly, where this dataset is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data. Digital data files are periodically updated. Files are dated, and users are responsible for obtaining the latest version of the data.

Native_Data_Set_Environment: Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; ESRI ArcCatalog 9.3.1.1850 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The attributes in this dataset were developed and verified by staff of the Geological Survey of Alabama according to the publication noted in Data_Set_Credit. Logical_Consistency_Report: These data are believed to be logically consistent. Chain-node topology are present. Checks were made to ensure that no two chains occupy the same space or that a single chain contains two classifications. Snapping was used intermittently. Completeness_Report: Completeness of these data reflects the publication noted in in Data_Set_Credit. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Reporting and basemap data used for polygons does not provide detailed information as to how coordinates were acquired or the shoreline scale.

The scan was georeferenced to a 1:80,000 shoreline and infrastructure. Polygons were digitized on screen, shapefile projected and attribute fields created. The Shepard Sediment Classification Diagram was used to convert the published sediment type graphics into a more meaningful attribute.
