Forestry
Satellite imagery for forest estates and plantations
Tree heights from stereo imagery, and a dated record of what was cleared and what was replanted. Archive and new captures from more than 100 satellites, priced per km².
Tree heights come with every stereo order
A stereo order includes a 0.5 m surface model, a bare-earth terrain model, and the difference between them: height above ground. Every crown the satellite saw from both angles gets a height.
Under closed canopy, stereo can't see the ground. There the terrain is filled in from measured ground nearby, and each filled cell is labelled, so your analysts can keep or drop it. We checked the models against NASA's ICESat-2 laser at Kimberley, in South Africa's Northern Cape. In tall, closed stands, check a sample against your own plots or recent LiDAR.
Other forestry jobs, and what to order
- Clearing since the last look
- Order two captures of the same area and we compare them for you. Change detection outlines what differs between the dates as separate objects, quoted per job.
- A replanted block, year by year
- Book captures weekly to quarterly. Free Sentinel-2 in Pera Portal fills the gaps with a 10 m vegetation index.
- Estates under cloud
- Radar sees through cloud and at night. KOMPSAT-5 archive is priced per km², and new radar captures are quoted on request.
- EUDR evidence for wood
- An image of each plot near 31 December 2020 and a recent one, over the same geolocated polygons.

We'll tell you what the archive holds over it, whether stereo has been captured there, and what new captures would cost.
