Summary[edit]

Description
English: The Tefedest, a granite mountain range in the central Sahara.

The image is averaged from 11 Landsat 8-scenes, provided by NASA. Bands 4, 3, 2 and 8 were combined into an RGB image. Panchromatic sharpening, conversion to radiance, weighted averaging, and rescaling to extrema of the scenes was done in R with the package RStoolbox. Color processing in GIMP to deal with very bright spots. JPEG-encoded with Guetzli.

Images acquired in the range 23 November 2013 – 15 March 2020.

Resolution: 15m.

Projection: UTM 31 N, WGS84.
