Heat mapping Fairfax City and George Mason University campus
The Challenge
Temperatures are often exacerbated in cities as sidewalks, buildings, and other human-built structures retain and reflect heat differently than natural elements. This causes cities to experience higher temperatures, coined urban heat, and can negatively impact public health and infrastructure in affected regions.
The Project
VCC researchers and students have been collecting temperature data during record hot days of Summer 2024 and 2025 to create maps visualizing real-feel temperatures across George Mason University’s Fairfax campus and Fairfax City. To collect the data, temperature sensors are mounted onto backpacks, bicycles, and cars that record temperature measurements on high traffic surfaces such as sidewalks and roadways during morning, afternoon, and evening hours. The data is then cleaned and displayed on maps that are passed on to decision makers that will use the information to develop heat mitigation strategies and ensure the safety and comfortability of Fairfax City residents.
Who’s Involved?
This work is led by VCC urban heat expert Luis Ortiz and GIS specialist Matt Rice in close collaboration with staff at the City of Fairfax.
