Working Groups

We currently have several active Working Groups and Ad-Hoc Task Forces that contribute to national-level requirements, lead the development of guidelines & standards, provide feedback on prototype tools, inform training priorities, and guide other key efforts at NAPSG Foundation. Our Working Groups are comprised of public safety leaders, operators, GIS professionals, private sector representatives, and others who support our shared mission. If you would like to join an existing working group or have an idea for starting a new working group, please contact us.
