Salt River Pima–Maricopa Indian Community

Arizona—The Salt River Pima-Maricopa Indian Community (SRPMIC) is a reservation established in 1879 for the Pima and Maricopa people. SRPMIC is composed of 53,000 acres located in Arizona adjacent to Scottsdale, Mesa, Tempe, and the town of Fountain Hills. SRPMIC is implementing a unique GIS to serve its community members. Based on ESRI's ArcInfo software, SRPMIC's GIS will develop an extremely accurate cadastral measurement database maintained by surveying and legal description data. Unlike traditional coordinate-based mapping systems, SRPMIC's measurement-based GIS will store the original surveying measurements to create an accurate, verifiable cadastral base rather than obtaining discrete coordinates derived from digitizing existing source maps.

By storing the cadastral measurements, SRPMIC's GIS database can be automatically readjusted whenever datum changes or survey control modifications occur. Additionally, an online record of the original legal descriptions, as well as a complete cadastral chronology, will be stored simultaneously as SRPMIC's digital cadastre is developed over time. In effect, the GIS graphic representation for the community will be created and automatically maintained through the input of textual legal descriptions.
