Approximately 44,500 Landsat Thematic Mapper (TM) scenes acquired from July 16, 1982 through September 27, 1985 by Landsats 4 and 5 are now available for purchase in digital formats from the U.S. Geological Surveys (USGS) Earth Resources Observation Systems (EROS) Data Center (EDC).
TM scenes can be acquired by any customer, without restrictions on data use or sharing. Individual scenes are rated from 0-100% cloud cover and may show a choice of several acquisition dates for the same site during each year.
TM digital products are priced according to the type of geodetic reference data applied to the product. Systematically corrected TM scenes are processed using predicted geodetic position information downlinked with the sensor data. Precision corrected TM scenes are registered to topographic maps and are geodetically accurate to approximately one pixel. Products are framed according to the World Reference System 2 (WRS2) standard, and each WRS scene contains approximately 75 MB for each of 7 spectral bands. The radiometric correction process applied to each TM product is identical. Both products are available in one of several customer-specified map projections.
TM digital products are sold on either 9-track or 8-mm tape media for:
TM photographic products are not available.
More than 350,000 scenes of Landsat Multispectral Scanner (MSS) data collected between 1972 and 1992 will continue to be available to any customer, without restrictions, at $200 per scene.
