Quick Data Rundown

Heat Analysis: Citywide maps of land-surface temperature with modelled air temperature, heat-stress risk, UV guidance, and historical trends to track progress and target cooling actions.

Water Quality: Satellite-driven indicators for chlorophyll-a, blue-green algal bloom risk, turbidity, Secchi disk depth, and surface temperature, delivered as status, trends, and alerts for lakes and slow rivers.

Shade Mapping: Time-of-day and seasonal shade coverage across parks, streets, and buildings to guide planting, canopies, and comfort routes.

Discover use cases

Cool the Hottest Streets: We detect heat hotspots and estimate near-surface air temperature to reveal where people face the greatest exposure. Results guide shade trees, cool materials, and misting stations, then track progress year over year.

Safer Summers by the Lake: We deliver water quality metrics trends for lakes, reservoirs, and slow rivers. Early warnings help you communicate risks, protect public health, and optimize maintenance and aeration.

Irrigate What Matters: At ~3 m resolution, we prioritize zones that need water. You get a simple schedule and a map, so crews irrigate efficiently and timely.
