Paper Abstract

The Landsat-D systems offer several improvements in terms of observations from space for the Earth resource manager and scientists studying processes that occur on the surface of the Earth. The principal and new observing instrument, the thematic mapper (TM), will provide higher spatial resolution (30 m) than the radiometric observations provided from Landsats 1 through 3 (80 m), and, in addition, observations in new spactral bands (0.45 to 0.52, 1.55 to 1.75, and 2.08 to 2.35 micrometers) will be available. These characteristics in themselves are expected to offer considerable advantages in identifying crops and assessing the acreage and condition. Further advantages will also be realized in mineral exploration and land resource assessment efforts. The recently revised Landsat-D program calls for the launch of the first spacecraft (Landsat-D) in the third quarter of the 1982 calendar year with a multispectral scanner (MSS) on the spacecraft and a TM, if it is available. The second spacecraft (Landsat-D'), to be launched 12 to 15 months after Landsat-D, will include an MSS and a TM. The capability for processing the MSS data from Landsat-D should be operational by January 1983. The operational capability for processing TM data should exist in January 1985.
