In 2020, NOMADICS developed a user-friendly, interactive tool to track, monitor, and visualize the localized spread of COVID-19 across New Jersey, including:

  • Current information and weekly changes on COVID-19 cases and deaths
  • Current information on COVID-19 vaccinations, provided at the county level
  • Locations of COVID-19 vaccine providers

This powerful intelligence tool—dubbed Project Broad Street—aggregates and automates publicly-available GIS datasets from various public and private entities, such as The Johns Hopkins University and the Centers for Disease Control and Prevention. The data, mapping interface, and layers are consistently maintained, monitored, and updated by NOMADICS, giving State COVID responders a centralized data platform to contain infections and limit the spread of this deadly pandemic.

The initiative was funded solely by NOMADICS as part of a Research & Development expansion that started in April 2020 and concluded its initial phase in January 2023.

Project Broad Street was nominated for a 2021 ANJEC Environmental Achievement Award.

Throughout 2020 and 2021, Project Broad Street was duplicated for other states and regions. These web maps provide an overview of COVID-19 cases and response resources in various states nationwide. Each featured web map identifies COVID-19 and its hotspots, providing up-to-date information on the number of COVID-19 cases and deaths—along with a weekly percent change in cases and deaths—and the number of administered COVID-19 vaccinations at the county level.

The tool for New Jersey—dubbed Project Broad Street—was duplicated for other states and regions to help curb the spread of the virus on a regional and local level.
