This coverage represents offshore production platforms and well caissons that are associated with the production of hydrocarbons underlying Alabama's Offshore region. Data used to generate this coverage are filed with the OGB. Purpose: The State Oil & Gas Board of Alabama (OGB) is a regulatory agency of the State of Alabama with the statutory charge of preventing waste and promoting the conservation of oil and gas while insuring the protection of both the environment and the correlative rights of owners. The OGB is granted broad authority in Alabama oil and gas conservation statutes to promulgate and enforce rules and regulations to ensure the conservation and proper development of Alabama's petroleum resources. In addition to the OGB's regulatory responsibilities, the OGB also serves as an excellent source for oil and gas information, as well as environmental data, for industry, government, and the public. The OBG is the repository for all files containing permitting data, engineering data, production data, environmental data, base maps, and legal proceedings pertaining to oil and gas wells and fields. The OGB's GIS will provide the public and other state and federal agencies with a fully intergraded, complete set of shapefiles to aid in the regulation of and education about oil and gas exploration activities in Alabama. Supplemental_Information: The State Oil & Gas Board is the sister agency to the Geological Survey of Alabama. These agencies share a close working relationship regarding the development of GIS shapefiles.

State Oil & Gas Board of Alabama Online_Linkage: http://www.ogb.state.al.us Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Attribute accuracy is tested by manual comparison of the source with hard copy printouts and/or symbolized display of the digital structures data on an interactive computer graphic system. Attribute information is collected from the legal files of the State Oil & Gas Board of Alabama. Attribute tables are created in Microsoft Excel and joined to shapefiles using ESRI ArcInfo software. The OGB checks all entities and their attribute data for compliance with FDGC data standards. These checks do not ensure that data accurately reflects conditions in the field only that the attributes meet database design specifications. Quantitative_Attribute_Accuracy_Assessment: Attribute_Accuracy_Value: 100% Attribute_Accuracy_Explanation: Attributes for each structure were compared with data on file with the State Oil & Gas Board of Alabama. Logical_Consistency_Report: Point data for offshore platforms and well caissons are represented by one set of geographic coordinates for each point. The State Oil & Gas Board of Alabama (OGB) is responsible for ensuring 1) that all geospatial data are complete and correctly projected to the proper geodetic datum, 2) that the attribute data are compliant with the OGB data standards. However, inconsistencies could exist in data submitted to OGB by companies. Logical consistency of OGB data cannot be guaranteed. Completeness_Report: Digital Point Shapefile of "Offshore Structure and Well Caissons in Alabama's State Waters, Mobile Bay, Alabama" is believed to be complete. OGB verifies each data set to ensure that all include the geospatial and attribute data, and metadata. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal positional accuracy for the digital data is tested by visual comparison of the source with media stable hard copy plots. Data used to generate the shapefile are obtained from survey plats and as-built drawings filed with the State Oil & Gas Board of Alabama (OGB). Horizontal accuracy of these data can only be accurate as the surveyed locations submitted by the operator to the OGB. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 95% Horizontal_Positional_Accuracy_Explanation: Horizontal accuracy is only as good as the surveyed locations submitted by the operator to the State Oil & Gas Board of Alabama. Locations are compared with media stable hard copy base maps.
