United States

A neighborhood heat scorecard for US planners.

Draw a district. See how long the air stays hot, how far the hotspot is from indoor public space, and where a planting sketch would land. Then export the brief.

• Duration

  Hours above a heat threshold versus the longest consecutive streak — summarized as an unrelieved-heat ratio (streak ÷ hours) on the same ~100 m air tiles, not a second product.

• Indoor access

  A walk from the hotspot to the nearest OSM library or community centre. Not an official cooling-center network.

• Planting sketch

  Pins on hottest fabric plus a literature canopy slider. Labeled as a sketch — not a new satellite heatmap.
