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 Le 04/04/2014 15:26, Jean-Guilhem Cailton a écrit : > Hi, > > Airbus Defence and Space, Geo-Intelligence has donated Spot-6 images, > acquired between 2013-10-13 and 2013-12-11, that cover a large part of > the area of the border between Northern Liberia and Southern Guinea, > including the towns of Voinjama and Kolahun in Liberia, as well as the > cities of Guéckédou and Macenta in Guinée, and their surroundings. > > Job 489 has been set up on the Tasking Manager: > http://tasks.hotosm.org/job/489 > > For the cities of Guéckédou and Macenta, where higher resolution > Pleiades images are available and that were already mapped (jobs 469 and > 471), it is better to keep using the Pleiades images as geometrical > reference, as they have better accuracy (6.5 m CE 90 without GCPs). > > Use source=Spot-6, Airbus > > Best wishes, > > Jean-Guilhem > > > _______________________________________________ > HOT mailing list > HOT@openstreetmap.org > https://lists.openstreetmap.org/listinfo/hot > _______________________________________________ HOT mailing list HOT@openstreetmap.org https://lists.openstreetmap.org/listinfo/hot
