The BLM makes images of GLO records (federal land patents, survey plats and field notes, land status records, and tract books) issued between 1787 and present publicly available on its website. [5] Since 1990, the BLM's Geographic Coordinates Database (GCDB) program has endeavored to generate coordinate values for each established PLSS corner ...
