BIA Tract Viewer Map Service

Metadata Updated: September 11, 2025

The BIA TAAMS Mapped Tribal Tracts and BIA TAAMS Mapped Tribal Parcels datasets depict tracts and parcels with Tribal ownership or are allotted. This dataset is organized y Land Area Code and Tract Number. This dataset is updated as mapped parcels are updated. This dataset only displayed mapped Tracts and Parcels and it may not be a full picture of Tribal Tracts and Parcels. If a parcel cannot be mapped for any reason, it may not be displayed in this dataset, thus this dataset should not be considered a complete picture of Tribal land. The BIA Mapped Tribals Tract and BIA Mapped Tribals Parcels servicesdisplay the same data. A parcel is a subdivision of a tract. Ownership is indicated in both the Tract and Parcel dataset in the 'Ownership' field. An Ownership value of 'T' indicates Tribally-ownership and an ownership value of 'A' indicates the tract and parcel is allotted. The Division of Land Titles and Records (DLTR) compiled the data to support the Bureau of Indian Affairs. The source information for tract data is the Trust Asset and Accounting Management System (TAAMS), which is the system of record.
