Landsat TM - Landsat Thematic Mapper. Earth observation satellite with seven bands at 30m spatial resolution (TWS).
Layer - Distinct map theme. Usually a separate GIS file (TWS).
LANDSAT TM
Landsat TM is more advanced multispectral scanner than the MSS system. The spectral resolution encompasses seven bands that range from visible blue to thermal infrared. Included is a Mid Infrared (MIR) band.

Following that is a Landsat TM (30m) not quite true color composite of Baghdad and the areas south of Iraq. Landsat image courtesy of GLCF. These may be the scenes of major battles in coming weeks.
The raw image data (LANDSAT TM and SPIN-2) used to create the sample images are provided by the US Government through Eastman Kodak Company as part of the Multi-Modality Image Fusion Study project and are used here with their permission.
Satellite imagery such as Landsat TM and SPOT provide multispectral images of the earth, some containing seven or more bands.
Longley and Mesev (1997) use information from the 1991 UK small area census statistics as ancillary information to improve the classification accuracy of a contemporary (LANDSAT TM) image of Bristol.
Landsat TM data from May and September of 1986 processed by methods developed by Koeln and Wesley (1987) and Koeln et al. (1988) were used. The digital image processing techniques created a GIS data layer for land use and land cover.

developed various different products to process satellite imagery from AVHRR, Landsat MSS, Landsat TM and SPOT imagery into land cover / land use maps, map deforestation, and assist in locating oil reserves.
See the exercise on Remote Sensing for an example of converting a 7-band LandSat TM image to a series of 7 grids. Converting single-band images is performed in the same manner, except that only a single output grid is created.
A standard color display of multispectral image displays three bands, one each for red, green and blue. Satellite imagery such as Landsat TM and SPOT provide multispectral images of the earth, some containing seven or more bands.
