Our Mission

The mission of the Branch of Geospatial Support is to assist Tribal governments and Indian Affairs to manage the cultural and natural resources of Indian Country by providing Geographic Information Systems software, training and technical support.

Bureau of Indian Affairs Land Area Representation Dataset

The Land Area Representation (LAR) dataset is the Bureau of Indian Affair’s (BIA) official geospatial representation of American Indian land areas for federally recognized tribes. The BIA LAR dataset is used as the authoritative land area for the BIA’s mission.  The LAR dataset is publicly available, with published guidelines on how to use the data appropriately.

The LAR dataset is currently being modernized and will be updated later in 2022 with a regular update schedule.

Who We Serve
