Survey Notes, Plats, and Land Records Information

General Land Office All Female Survey Crew

The BLM currently has four different online systems for searching land records:


LR2000, provides reports on non-Alaska BLM land and mineral use authorizations for oil, gas, and geothermal leasing, rights-of-ways, coal and other mineral development, land and mineral title, mining claims, withdrawals, classifications, and more on federal lands or on federal mineral estate. This is a text- based system (i.e. no online maps).


Navigator is your one-stop shop for keyword and geospatial search of BLM data. In just minutes you can search our trove of maps and datasets which you can annotate, edit and save with ease.  Navigator provides a centralized location to discover and access BLMs geospatial data and serves both internal BLM staff as well as the general public. Navigator indexes and provides access to geospatial data from project, state and national levels, so everything from small scale projects to national data compilations can be shared internally and externally . Future plans include exposure of more web and map services to allow for direct use and analysis of BLM data.


To search land records in Alaska, visit the Alaska Spatial Data Management System website (SDMS). SDMS is a one-stop tool to view, research, print and download information such as surveyed  land parcels, land status, mining claims, and Master Title Plats.
