Pima Association of Governments' GIS program develops and produces data sets and maintains several GIS data layers and databases. The program provides GIS modeling, analysis and mapping for PAG programs and jurisdiction members. The program also manages the Regional Remote Sensing Program. Other GIS analysis and products include: database applications, custom maps, GIS analysis, demographic profiles and interactive mapping applications.

PAG produces customized maps ranging from simple location maps to complex GIS applications that use various database and data layers. GIS is used to support PAG's major program areas with planning applications, such as demographics, environment, land use and transportation. The mapping products are produced in hard copy formats and digital files such as pdfs and ESRI shapefiles.

Statewide Employer Viewer

PAG collaborated with other metropolitan planning organizations and councils of government in Arizona in the development of an online tool that identifies employers with five or more employees. The new tool also identifies what types of businesses are here, how they are clustered geographically (e.g., the number of aerospace companies located in different parts of the region), and what aggregate levels of employment may be.

Detailed employment data is critical to regional transportation planning and decision making, as well as for business attraction and expansion efforts.

Aerial Imagery (Orthophotography) Elevation Data Sets

Since 1988, PAG has obtained orthophotos for eastern Pima County. The latest imagery was obtained in May 2015.

Information and elevation data may be ordered online

LiDAR - Light Detection and Ranging

LiDAR is a remote sensing system used to collect elevation data. PAG's latest LiDAR data was obtained in February 2015. PAG has incorporated LiDAR data sets commencing with its 2005 aerial flight. Bare-Earth digital elevation models were also derived from the LiDAR data sets for PAG's 2008 Ortho Project. Classified LiDAR *.las files and Bare Earth DEM flies can be ordered online.
