&times;<br>A map of individual trees in NYC at the genus level

This map shows ~1.8 million individual tree crowns in New York City,<br>each labeled with its genus (e.g. oak, maple). It contains both trees that were measured in the<br>manual inventory,<br>and trees that we classified from PlanetScope satellite imagery and airborne<br>lidar — including trees on private property and in natural areas.<br>This makes it the most comprehensive available map of tree identity in NYC.

How to read it

Color shows genus — see the legend at right. Click any<br>genus in the legend to highlight just that one across the whole city;<br>click it again (or "Show all genera") to reset.

Click any polygon for its genus, whether it's a<br>ground-truthed observation or a remote sensing-based prediction, and<br>how certain the classifier is that the tree is in fact the<br>predicted genus.

Good to know

Only the 18 most common genera citywide are classified (about 78%<br>of total basal area); rarer genera are not included.

Overall accuracy is 82% but more common genera tend to have higher<br>accuracy and less common genera (e.g. birch) are<br>less reliable.

We use tree crown polygons provided by<br>TNC/UVM;<br>making these polygons is tricky and segmentation isn't perfect;<br>read the paper for more details and limitations.

Visualization options

Tree data source (legend, bottom): show only<br>ground-truth street tree records, only classifier predictions, or<br>all trees (the default).

Fade by classifier probability (legend, bottom):<br>select this option to show classifier probability. When on, tree<br>polygons that the classifier was less certain about are shown with<br>higher transparency. Off by default, so every polygon is fully<br>opaque regardless of probability.
