Landsat eight is the newest satellite tv for pc in the Landsat program. The data high quality (sign-to-noise ratio) and radiometric quantization (12-bits) of the Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) are higher than previous Landsat devices (eight-bit for TM and ETM+). Since it’s launch on February 11, 2013, Landsat 8 has been providing some truly gorgeous pictures of the earth’s floor. Beyond their beauty, these photographs are filled with information which may be manipulated to extract options and discern adjustments to the earth’s surface over time.

The Albers coordinates of the WELD pixels have a sub-pixel misalignment with the Albers coordinates defining the U.S. National Land Cowl Data dataset. The WELD Albers projection origin doesn’t fall completely at a WELD product pixel center. For example, the CONUS projection origin is in horizontal tile 17, vertical tile 22 at column 520.000, row 493.333, and the Alaska projection origin is in horizontal tile 5, vertical tile 16 at column 3390.000, row 2478.333 (the place column zero.5, row zero.5 refers to the center of the NW pixel of a tile). This difficulty might be rectified in the subsequent WELD product model.
