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.

LiDAR - Light Detection and Ranging

Lidar is a remote sensing system used to collect elevation data. 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. The LiDAR elevation data set (DEM-Bare Earth) can be ordered online.
