We specialize in mangrove ecosystems, deriving information from satellites, drones and mobile technology to assess coastal forests and wetlands in time and space, including carbon storage, dynamic changes, stand age, relative canopy height, and degradation.

Mapping mangrove extent for sustainable development goal (SDG) reporting
We have developed completely automated and validated methods for mapping mangroves, using powerful cloud computing and machine learning algorithms. We provide national scale mangrove maps over time periods of up to three decades.
In the image on the left, stable mangroves are shown in green, gains in light green, losses in red. There is extensive mangrove loss in the northern area, with new mangrove accretion in the channel islands.
Drone-based mangrove surveys
Combining visual and near-infrared cameras mounted on drones we can develop three-dimensional views of forest structure as well as vegetation indices to assess forest health, degradation.

Mangrove extent and condition in Madagascar
we used cloud computing and three decades of satellite imagery to assess status and trends of mangrove ecosystems in Madagascar. These maps are validated, with over 90% accuracy. Explore the interactive map below. read the report in French and English.

Our automated methods are repeatable and transferrable. Calibrated with local information these provide more accuracy and detail than global datasets.
