[HOT] Spot-6 images of Guinée / Northern Liberia available, job 489

[Jean-Guilhem Cailton]

Hi,

Another version of the Spot-6 layer, with the near-infrared band used as
"red" in red-green-blue (instead of the natural red band) is available.

It provides a nice view of vegetation (in red), and thus also makes it
easy to see residential areas and rivers.

To add it, replace "spot6" by "spot6_nir" in the URL given in
http://tasks.hotosm.org/job/489

Best wishes,

Jean-Guilhem
