The algorithm identifies all pixels that are part of a tree and its shadow and calculates the heights of detected trees in SPOT, Pléiades, or Pléiades Neo display imagery. The result is a GeoTIFF file that maps the probability of each pixel being part of a tree.
Tree and tree height detection can be used for infrastructure vegetation risk monitoring, urban planning, and construction.
See more on the marketplace.
The algorithm has been developed using tens of thousands of semantically annotated images.
The accuracy is as follows:
- On isolated objects, with the entire shadow on level ground: 1–2 m
- In worse conditions: up to 8 m
The STAC item should be a SPOT, Pléiades, or Pléiades Neo image of the display radiometric processing level.
The STAC item should be CNAM-compatible. Check that the STAC item has been added to storage in 2023 or later.
Required parameters
Input imagery
You need to specify the STAC items you want to apply the process to.
Output title
You need to specify the title of the output objects. This title will be assigned to the resulting STAC item and STAC collection.
