Causey, J.D. 2006 1 vector digital data Digital Series DS-228 Menlo Park, CA U.S. Geological Survey http://pubs.usgs.gov/ds/2006/228 nv_pls_04Frank, D.G. The nv_pls_04 spatial data set (shapefile) contains Public Land Survey section polygons that had mining claims on December 31, 2004 as recorded in the U.S. Bureau of Land Management's LR2000 database May 26, 2005 for the period from 1976 to 2004. This spatial database was designed to be used with the U.S Bureau of Land Managemen LR2000 database. It contains a field, MTRS, which allows linking information in the LR2000 case_tbl and case_land tables. However, it is only valid for data downloaded from the LR2000 database May 26, 2005, since the database is dynamic and new information may have been added after that date, or older information corrected. en 20050526 Database date Complete Annually -120.004433 -114.038780 41.998730 35.011089 -120.004433-114.03878035.01108941.998730 None Mining claim Public Land Survey Meridian Township Range Section Nevada None None This spatial database is not meant to be used or displayed at any scale larger than 1:100,000 (for example, 1:24,000).
