100th story
"Sentinel Vision"


VisioTerra has developed the “Sentinel Vision Portal” enabling
European Space Agency (ESA) staff to get the best of Sentinel data.
Since March 20, 2017 VisioTerra edits 4 times a week
“stories” showing the smiles or injuries of the Earth
Summary of the 100 "Sentinel Vision" stories
The wealth of Sentinel data diversity


Stories involve radar images (Sentinel-1), high-resolution optical images (Sentinel-2), medium-resolution optical images for ocean-colour (Sentinel-3 OLCI), medium-resolution short and thermal infrared images (Sentine-3 SLSTR) or altimeter data (Sentinel-3 SRAL).
Each one of the 25 lines corresponds to one week (n°12 to 36).

Navigation in the 100th story

Qaasuitsup (Grennland) peat wildfire

Hyperlooks on the private “Sentinel Vision” portal have been replaced by hyperlooks on the public VtWeb portal.
You may activate the “hyperlooks” to navigate in the images (see the VtWeb videos in French or English).
An analysis of fire spreading in relation to the wind speed and extra Sentinel-3 OLCI images are given in the PDF file.
Animation showing the Sentinel-2 tile at five (5) dates is given in 3D_animation.
