United States Geological Survey (USGS) 1996 vector digital data Denver, Colorado USGS Central Energy Team http://energy.cr.usgs.gov/oilgas/noga/ The USGS Central Region Energy Team assesses oil and gas resources of the United States. The onshore and State water areas of the United States comprise 71 provinces. Within these provinces, hydrocarbon plays were defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes. The province boundaries were drawn on the county lines that most closely followed the natural geologic boundaries. These coverages illustrate the geologic boundaries of provinces as defined for the National Oil and Gas Resource Assessment Project. Hydrocarbon plays are generally defined and assessed within provinces. Oil and gas provinces are listed here by number, with their geographic extent and name: >Number West East North South Province Name > 1 -166.981709 -140.987511 71.439286 67.244643 Northern Alaska > 2 -173.226370 -140.990166 68.019992 58.497608 Central Alaska > 3 -172.721241 -129.990826 63.490419 52.197587 Southern Alaska > 4 -124.848972 -121.205451 49.002491 41.998336 Western Oregon -

The lins2cov.aml takes files from the NOGA 95 Spatial Data Disk (DDS-35), and reformats into Arc/Info Generate format (ASCII) files. They are then imported into ArcInfo coverages using the GENERATE command, subsequently they are cleaned to remove any potential overlap of polygons (using .000001 weed and fuzzy tolerances). Region/province numbers and names are appended to the file using lookup information acquired from tables on the NOGA 95 Tabular Information Disk (DDS-36).
