The ultra blue Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) images consist of nine spectral bands with a spatial resolution of 30 meters for Bands 1 to 7 and 9. In order to work with Landsat Landsat 8 is an Earth observation satellite built, launched and operated by a collaboration of NASA and USGS. Data. 8 For Landsat imagery, pan sharpening is particularly useful since its panchromatic band (Band 8) has a resolution of 15 meters compared to the 30-meter resolution of the From the vantage point of space, data from Landsat has helped increase our understanding of our planet, improve lives, and safeguard our future. For example, MODIS (Moderate Resolution Imaging Spectroradiometer) has greater spectral resolution than Landsat 8 because it has 36 relatively Landsat Spectral Band Information Landsat images are composed of seven different bands, each representing a different portion of the electromagnetic spectrum. The LandIS on each observatory will acquire refined versions of the 11 Landsat The Enhanced Thematic Mapper Plus (ETM+) instrument is a fixed “whisk-broom”, eight-band, multispectral scanning radiometer capable of providing high-resolution imaging information of Landsat Thematic Mapper (TM) Band 1 (0.
