Investigative journalism with satellite images (PART 1)

The first part of this three-part series will explore the value boundaries for satellite investigations. We will zoom in on illegal deforestation monitoring in the Amazon rainforest and discuss illegal fishing.

The merit of analyzing boundaries to preclude illegal activities

Update (August 26)

Checking for deforestation forest fires 🔥 within protected sectors: Black areas are protected under the WDPA classification and yellow/red spots are deforestation fires from 2020

Illegal fishing

Check this tutorial on how the 5GIT OSINT tool works. Indication for these interference tracks may suggest a potential existence of a defense system. This can then be checked with some boundary files that you have at hand.
