These ESRI shape files contain National Park Service tract and boundary data created by the Land Resources Division. The tract data is essentially all of the parcel boundaries associated within and adjoining the San Antonio Missions National Historical Park as legislated by congress. The boundary data is the current legislated park boundary. Tracts are created from deeds, plats and surveys of record then assigned a number by regional cartographic staff at the Land Resources Program Centers. This spatial data is used as the basis for NPS Land Status Maps.
