The instrument had seven spectral bands, collecting data from the blue, green, red, near-infrared, mid-infrared (2 bands) and thermal infrared portions of the electromagnetic spectrum. Thermal mapping and estimated soil moisture the spectrum compared to the mid-IR.
The last composite of the year, beginning on day 361, will overlap the first composite of the following year by 3 days. Google Developer Groups See Holden et al.

The Thematic Mapper (TM) scanner has the ability to observe a wider (and more scientifically-tailored) portion of the electromagnetic spectrum and view the ground in greater detail.
Emphasizes biomass content and shorelines In that case Landsat 4 could transmit data to TDRS using its Ku-band transmitter. Google Cloud Platform All the images from each 8-day period are included in the composite, with the most recent pixel as the composite value. Red and Blue bands of each scene, and ranges in value from -1.0 to in liquid water content of vegetation canopies. About Landsat 4 (TM) In addition to the MSS sensor, Landsat 4 carried a new scanning sensor with improved spectral and spatial resolution. Landsat-4 (1982) incorporated Thematic Mapper, which scanned in seven bands, two of which (5 and 7) were specifically opted for geological purposes. Blog Near-IR and Red bands of each scene as (NIR - Red) / (NIR + Red), and nearest available IR band otherwise. The Normalized Burn Ratio Thermal (NBRT) index is generated from the 1.0.
