The National Alliance for Public Safety GIS Foundation (NAPSG) has been a long time partner of GISCorps. Since 2017, NAPSG and GISCorps have partnered on over a dozen crowdsourced disaster relief responses involving hurricanes, earthquakes, tornadoes and flooding. Early iterations of the project were conducted using Esri’s Story Map Crowdsource template. It then evolved into Operations Dashboards using the Attachment Viewer web application. Now in 2020, a new iteration has been built using Experience Builder.

Slack channels have also become a critical facet of managing volunteers. CEDR Digital Corps, a fellow partner with a specialty in leveraging social media to help those in need, injected several helpful integrations between Twitter and Slack. We have added a validation team who confirms the locational accuracy of each post and populates value-added information such as structure damage level and FEMA Community Lifelines.

Though the technology is ever evolving, the main goal of the project is to provide early situational awareness to first responders and emergency managers at all levels. During large events, we are in daily contact with federal emergency managers. During smaller events, NAPSG ensures local emergency operation centers are well informed.

Current Activation: On Standby during 2020 Hurricane Season

The majority of these disaster response projects are crowdsourced, and therefore open to all volunteers. You can learn more about participating by reviewing the most recent evolution of our Volunteer Portal, built on Esri’s Experience Builder platform. Instructions, FAQs and a video showing the basic workflow can all be found on the Portal. We also have a 2020 Disasters Crowdsourced Photos Hub page for further exploration of the data. All data is open for use.
