Land manager or administrative agency (e.g. USFS, State Fish and Game, City Land, TNC) standardized for the US. See PAD-US Data Standard or the "Agency Name" look-up table included in the data download for full domain descriptions. Use "Manager Name" rather than "Owner Name" for the best depiction of federal lands as many overlapping designations (i.e. "Designation") and ownership related data gaps (i.e. "Unknown") occur in the federal theme. GAP attributes the applicable "Agency Name" to all records provided by the agency data steward in the "Manager Name" field. "Owner Name" contains 'unknown' values where parcel level ownership data are not yet available from authoritative data sources.
