## Why ?

<figure><img src="image_3.png" /></figure>

Remote sensing has a central role to play in many fields of application where science fronts cannot be attacked and overcome without the contribution of satellite products

## Remote Sensing Network

* Inter-divisions network : AE, ECODIV, ACT, AQUA, MathNum ...

* Bring together the community of experts and users of remote sensing data at INRAe.
## Objectives

* Detect-Classify-Estimate environment variables from space

* Model spatial structures and temporal dynamics

* Forest, crops, grasslands, water, soil

## Research
