Welcome to i-Tree Canopy!

Use this tool to classify land and tree cover across a given area using random sampling of aerial imagery. See tree canopy benefits in terms of carbon dioxide, air pollution, and stormwater impacts.

How to use it:

  • Select from existing geographic boundaries, draw your own project area boundaries onto Google Maps, or load an ESRI shapefile.
  • You can use multiple, non-overlapping boundaries at the same time.
  • i-Tree Canopy randomly generates sample points and zooms to each one so you can choose from your pre-defined list of cover types for that spot.
  • With i-Tree Canopy, you review Google Maps aerial photography at random points to conduct a cover assessment within a defined project area.
  • 500-1000 survey points are suggested; the more points you complete, the better your cover estimate for your study area.
  • If estimating tree cover, tree benefits can also be estimated.
