Land and Mineral Use Records

The Land and Mineral Use Records web site is an Internet mapping application within NILS' GeoCommunicator. It allows users to search, locate, and map the BLM's land and mineral use authorizations and mining claims on public lands throughout the United States. Land and mineral use authorizations include such things as oil and gas leases, rights-of-way, mineral leasing, coal leasing, unpatented mining claims, withdrawals, classifications, and land and mineral title.

The data for this system comes from the National Integrated Land System (NILS). The BLM maintains most of the land and mineral use authorizations and unpatented mining claims in a text-based system called "Legacy Rehost 2000" or, the "LR2000" system. The LR2000 system records tens of thousands of federal actions affecting public land or public mineral estate of the United States and hundreds of thousands of mining claims located on public lands. The BLM is processing the land and mineral use authorizations and unpatented mining claims from the LR2000 into NILS on a daily basis. The data from NILS is exported to NILS' GeoCommunicator every two-three weeks for the distribution of the data to the public. GeoCommunicator also provides links to serial register page and geographic reports from LR2000, Range Allotment reports from the Range Authorization and Billing System, and master title plats from many BLM state offices.

Most of the land and mineral records from NILS and LR2000 are available on GeoCommunicator, although not all. For more information see the Land and Mineral Use Records About page and check "What's New" for the latest information.

The map viewers work best in Internet Explorer. Pop-ups must be allowed.

Note: Not all data from LR2000 is on GeoCommunicator. More data will be added periodically, as more of the record data is converted into the NILS format. Some data will never be converted. Check the "What's New" page for the current list of available use authorization records. This application is not intended to replace the LR2000 system, but rather to provide the public and other governments the ability to map the land and mineral use authorizations and mining claim parcels.

There are no data download capabilities available at this time for the authorization data, but the following map services are available that can be used with GIS software.
