This CD-ROM contains an image from the Landsat7 satellite. The Landsat program has provided satellite remote sensing information to the world for over 28 years. LANDSAT 7 was launched on April 15, 1999. It includes the Enhanced Thematic Mapper Plus (ETM+) instrument, an eight-band multispectral scanning radiometer capable of providing high-resolution image information of the Earths surface. It detects spectrally-filtered radiation at visible, near-infrared, short-wave, and thermal infrared frequency bands from the sun-lit Earth. Nominal ground sample distances or "pixel" sizes are 49 feet (15 meters) in the panchromatic band; 98 feet (30 meters) in the 6 visible, near and short-wave infrared bands; and 197 feet (60 meters) in the thermal infrared band. The satellite orbits the Earth at an altitude of approximately 438 miles (705 kilometers) with a sun-synchronous 98-degree inclination and a descending equatorial crossing time of 10 a.m. LANDSAT Worldwide Reference System will be maintained with periodic adjustments for the life of the mission. The LANDSAT World-Wide-Reference system catalogues the world’s landmass into 57,784 scenes, each 115 miles (183 kilometers) wide by 106 miles (170 kilometers) long. This image on this CD-ROM is from path 42 and row 34.
