Lumen Urban Heat Atlas is an exploratory mapping tool that reveals how heat exposure varies at the street and block level. Traditional climate maps often operate at coarse resolutions, masking the real differences residents experience in their daily environments. Lumen integrates satellite‑derived land surface temperatures, tree‑canopy density, building geometry, and pedestrian‑level observations to create a fine‑grained picture of urban heat.
The platform allows users to compare neighborhoods, identify hotspots, and explore correlations between heat exposure and factors such as green space, housing density, and socio‑economic indicators. It is designed for early‑stage planning and community engagement rather than technical climate modeling. The interface emphasizes clarity and accessibility, making it easy for non‑experts to understand where interventions like shade structures, tree planting, or reflective surfaces could have the greatest impact.
Lumen is modular, allowing additional datasets—such as mobility flows or public‑health indicators—to be layered in as the project evolves. The goal is to support more equitable and data‑informed urban cooling strategies.
