The Global Land Survey (GLS) 1975 is a
global collection of imagery from the Landsat Multispectral Scanner
(MSS). Most scenes were acquired by Landsat 1–3 during the
years from 1972–1983. A few gaps in the Landsat 1–3 data
have been filled with scenes acquired by Landsat 4–5 during the
years 1982–1987.
These data contain 4 spectral bands:
Green, Red, an NIR band, and a SWIR band. In the typical false-color
presentation the images appear red because the NIR band, displayed as
red, highlights vegetation.
All scenes in the collection are included in this composite image.
