The Navajo Tribal Utility Authority GIS/GPS (Geographic Information System/Global Positioning System) Department resides within the Engineering and Technical Services Division. The GIS/GPS Department creates and maintains spatial information to aid in the creation of maps and data analysis to support NTUA departments, districts, Navajo Nation departments/agencies and individual NTUA customers. The GIS database provides a complete inventory of data layers available for electric, natural gas, solar energy, wastewater treatment, water and other useful information. Current base map layers include property parcels, transportation, landmarks, and buildings. One-foot aerial photography, DEM (Digital Elevation Model), DOQQ's (Digital Orthophoto Quarter Quadrangle), and DRG (Digital Raster Graphic) are available for the entire Navajo Nation. Maps and related data can be provided to users, customers, or contractors on physical media (plots and photocopies) or as electronic files on CD-ROM for a nominal fee.
