This geographic information system combines detailed information and location coordinates for oil wells, gas wells, and pipelines from the Commission's files with base map data captured from U.S. Geological Survey 7.5 minute quadrangle maps. These interactive maps were developed using Environmental Systems Research Institute, Inc. (ESRI) ArcIMS software, and interface with the Commission's Production Data Query and Drilling Permit Query applications.

Abstract: This map layer includes railroads in the conterminous United States and Alaska. This is a replacement for the December 1998 map layer. Purpose: These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000 data. No responsibility is assumed by the National Atlas of the United States in the use of these data.

A Cartographic Feature File (CFF) is a digital data file containing a vector representation of the point and line features shown on a Forest Service Primary Base Series (PBS) map. The feature categories contained in the CFF are transportation (roads and trails), streams and water bodies, political and administrative boundaries, land ownership, and other cultural features. Elevation contours, vegetation, and text (geographic names, labels, etc.) are not included in the CFF. CFFs are formatted according to the U.S. Geological Survey (USGS) quadrangle convention: 1:24,000-scale, 7.5-minutes latitude by 7.5-minutes longitude format. CFFs provide a consistent base set of geographic features for use in Forest Service geographic information systems (GIS). CFFs can be used individually or joined to form larger project areas. CFFs are also used as the source for the automated production of PBS maps.
