#### Description

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.

### Bands

**Bands**

Pixel size: 60 meters (all bands)

| Name | Pixel Size | Wavelength | Description |
|---|---|---|---|
| `10` | 60 meters | 0.50 - 0.60 μm | Green |
| `20` | 60 meters | 600-700 μm | Red |
| `30` | 60 meters | 0.70-0.80 μm | Near infrared |
| `40` | 60 meters | 0.80-1.10 μm | Short-wavelength infrared |
