A complete set of wells associated with oil, natural gas, and coal bed natural gas development in the western states as of June 2004. This is a static dataset even though liquid energy development is a highly dynamic endeavor. Because these well location datasets are generally housed and managed by various state-based agencies (typically the state Oil and Gas Conservation Commissions) a uniform, spatially precise coverage for the western United States has not been available to date. This layer consolidates the best available well location data from ND, SD, MT, WY, CO, NM, UT, AZ, OR, and CA (ID and WA do not report any liquid energy development) and standardizes the attributes. While static as of June 2004 the well...

Major roads in northern North America as determined by the U.S. National Atlas and The National Atlas of Canada (geogratis.cgdi.gc.ca). National data layers were re-attributed and merged to create a seamless major road layer for North America.
Cellular phone microwave towers registered with the U.S. Federal Communications Commission. Not all antennas are required to be registered with the FCC, therefore, this data set does not necessarily depict all cellular phone communication towers actually present on the landscape. The source data are updated weekly by the FCC as new permits are issued. However, this particular data set is designed for a specific analysis, and is planned to remain static as of the publication date (11/06/2003).

Powerlines in the western United States and Canada as identified by the 22 source data layers used to compile this shapefile. Source data were collected by personal contact or through the internet in the winter and spring of 2004 and assimilated using ArcGIS. This file is a complete record of overhead powerline data that was available as of 5/15/2004 but IS NOT INTENDED TO BE A COMPLETE REPRESENTATION OF THE SUM TOTAL OF ALL POWERLINES ON THE GROUND. These data primarily depict the higher voltage, long distance transmission lines but some arcs likely represent lower voltage distribution lines.
