Después de una pregunta de Humberto, una cobertura Landsat-8 de Bolivia
esta disponible, en "colores naturales" (rojo, verde y azul - Landsat
canales 4, 3 y 2), y también en "falsas colores" (infrarrojo, infrarrojo
cercano y verde - Landsat canales 7, 5 y 3), como sugerido por
Harrierco. (Para mapear la Amazonia, esa hace mas visibles los ríos).

Las imágenes tienen menos de 10% de nubes, y fueron tomadas entre
augusto 2013 y febrero 2014.

After a request from Humberto, a Landsat-8 cover of Bolivia is
available, in "natural colors" (red, green and blue - 4, 3 and 2 Landsat
bands), and also in "false colors" (infrared, near infrared, and green -
7, 5 and 3 Landsat bands), as suggested by Harrierco. (This makes water
more visible).

The images have less than 10% cloud cover, and were taken between August
2013 and February 2014.


Thanks to USGS for allowing on-demand processing of these images while
Landsat-8 cache reprocessing with improved calibration is on-going.

Best wishes,


Après une demande d'Humberto, une couverture Landsat-8 de Bolivie est
disponible, en "couleurs naturelles" (rouge, vert et bleu - canaux
Landsat 4, 3 et 2), et aussi en "fausses couleurs" (infrarouge, proche
infrarouge et vert - canaux Landsat 7, 5 et 3), comme suggéré par
Harrierco. (Cette combinaison rend l'eau plus visible).

Les images contiennent moins de 10% de nuages, et ont été prises entre
août 2013 et février 2014.
