Bureau of Land Management - New Mexico State Office 20120131 vector digital data http://www.blm.gov/nm/st/en/prog/more/geographic_sciences/spatial_data_metadata.html This data was collected by the U.S. Bureau of Land Management (BLM) in New Mexico at both the New Mexico State Office and at the various field offices. This dataset is meant to depict the federal mineral (or subsurface) interest of land parcels within New Mexico. No attempt is made to depict the mineral interest of non-federal entities. BLM's Master Title Plats are the official land records of the federal government and serve as the primary data source for depiction of federal mineral interest lands. Auxilliary source are referenced, as well, for the depiction of federal mineral interest. Collection of this dataset began in the 1980's using the BLM's ADS software to digitize information at the 1:24,000 scale. In the mid to late 1990's the data was converted from ADS to ArcInfo software and merged into tiles of one degree of longitude by one half degree of latitude. These tiles were regularly updated. The tiles were merged into a statewide coverage. The source geodatabase for this shapefile was created by loading the merged ArcInfo coverage into a personal geodatabase. The geodatabase data were snapped to a more accurate GCDB derived land network, where available. In areas where GCDB was not available the data were snapped to digitized PLSS. This shapefile has been created by exporting the geodatabase feature class. To provide a current delineation of federal mineral (subsurface) ownership in the state of New Mexico. 20110415 publication date Complete As needed -109.262405 -102.884004 37.035777 31.314334 User Defined Federal minerals Minerals Mineral interest Mineral ownership Mineral management Subsurface None New Mexico Restriction Code: other restrictions; Other Constraints: Access constraints: none Bureau of Land Management - New Mexico State Office GIS Manager Geosciences Team Lead 505-954-2000 Monday thru Friday: 8:00 am - 4:00 pm Mountain Time U.S. Bureau of Land Management - New Mexico State Office Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; ESRI ArcGIS 10.0.2.3200 Original data is in ESRI geodatabase format (SDE). The data was built to check for topological errors and verified that there were none. Also, data was verified that no label errors existed. The data is considered to be a complete picture of the federal mineral (subsurface) ownership on land in the state of New Mexico. Every effort is made to reference official, federal land records No effort is made to track non-federal mineral interests, unless they return to federal ownership. U. S.
