A map of individual trees in NYC at the genus level
This map shows ~1.8 million individual tree crowns in New York City,
each labeled with its genus (e.g. oak, maple). It contains both trees that were measured in the
manual inventory,
and trees that we classified from PlanetScope satellite imagery and airborne
lidar — including trees on private property and in natural areas.
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
genus in the legend to highlight just that one across the whole city;
click it again (or "Show all genera") to reset.
Opacity shows predicted probability from the classification: solid,
fully opaque polygons are either high-probability predictions or known
ground-truth street tree records; faint, transparent polygons are
lower-probability classifier guesses.
Click any polygon for its genus, probability, and whether it's a
ground-truthed observation or a remote sensing-based prediction.
Good to know
Only the 18 most common genera citywide are classified (about 78%
of total basal area); rarer genera are not included.
Overall accuracy is 82% but more common genera tend to have higher
accuracy and less common genera (e.g. birch) are
less reliable.
We use tree crown polygons provided by
TNC/UVM;
making these polygons is tricky and segmentation isn't perfect;
read the paper for more details and limitations.
