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.
Click any polygon for its genus, whether it's a
ground-truthed observation or a remote sensing-based prediction, and
how certain the classifier is that the tree is in fact the
predicted genus.
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.
Visualization options
Tree data source (legend, bottom): show only
ground-truth street tree records, only classifier predictions, or
all trees (the default).
Fade by classifier probability (legend, bottom):
select this option to show classifier probability. When on, tree
polygons that the classifier was less certain about are shown with
higher transparency. Off by default, so every polygon is fully
opaque regardless of probability.
