Help your municipality care for its trees. Satellite images show which trees are struggling. You go and take a look, guided step by step by tree technicians. Together we become the keepers of our trees.
Satellites see the canopy. You see the understory.
We assess the health of every tree from satellite images, again and again, across the whole city.
When a tree's health drops, it shows up on the map. Residents nearby go and check it, as citizen scientists.
Simple, step-by-step checks written with tree technicians, so every observation is useful to the people who maintain the trees.
Collaborative surveys, points and streets to adopt: urban green made into a shared game, on a serious technical backbone.
Add a tree by tapping the map or using your location. Colours show health at a glance.
