How to see trees and plants in a whole new light
A hyperspectral snapshot captures all the light in a scene, not just colours or infrared light. The extra information is useful in many applications, from agriculture and conservation to forensics and food safety.
New remote sensing method helps monitor the results of peatlands rehabilitation
Aalto University researchers have led the application of a new remote sensing method for monitoring the effects of rehabilitation efforts of petlands,
An encounter between a photographer and remote sensing specialists led to a book on forests, vision and the purpose of science

Albedo matters for the climate and forestry can have an impact on it
A research project conducted by Aalto University found that favoring broadleaved species in boreal forestry is a climate-friendly option when considering the forest albedo. Therefore, forest management actions can directly affect forest albedo, and hence the climate, without decreasing forest productivity.
