I now want to calculate the NDVI and do some land cover classification on these scenes using R and its RS packages, but first need to apply some corrections to these scenes. Landsat 8 has two additional multispectral bands, two narrower TIR bands in place of the single Landsat 7 TIR band and a panchromatic band for a total of 11 bands. The two additional bands are a narrow Coastal Aerosol band at a slightly shorter wavelength than the blue band and a Cirrus band sensitive to radiation wavelengths between 1.36 and 1.38 microns. The original Landsat 8 Surface Reflectance Code (LaSRC) algorithm was developed by Dr. Eric Vermote, National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC), and was modified The approximate scene size is 170 km … Landsat 8 SR data products are generated from specialized software called Landsat 8 Surface Reflectance Code (LaSRC). It launched in 1999 and has 15 x 15 meter pixel resolution (as opposed to 30 x 30 meter resolution for Landsat).

The Landsat Thematic Mapper (TM) sensor was carried on Landsat 4 and Landsat 5, and created images consisting of six spectral bands with a spatial resolution of 30 meters for Bands 1-5 and 7, and one thermal band (Band 6). Landsat is without a doubt one of the best sources of free satellite data today. Managed by NASA and the United States Geological Survey, the Landsat satellites have been capturing multi-spectral imagery for … Step 2 Select your data to download in the “Data Sets” tab. 3D Digital Elevation Models (DEMs) Gallery In addition to the orthorectification of satellite image data, the DEM's are utilized in support of the pre-planning and lay-out of corridor surveys, area developments, seismic line locations, well sites and engineering, construction … Aster vs. Landsat Satellite Imagery Comparison (Click Here for Landsat 8 - Sentinel-2 Comparison)Aster satellite imagery, like Landsat, is free. The Datasets tab answers the question: What satellite or aerial imagery are you looking for? I am analyzing several LANDSAT scenes from the LANDSAT 8 OLI mission (18 in total, all from Jan 2017 - cloud cover < 20%).

The USGS Earth Explorer remote sensing datasets are plentiful: aerial imagery, AVHRR, commercial imagery, digital elevation models, Landsat, LiDAR, MODIS, Radar and more.
