NASA’s Goddard Space Flight Center has released the Advanced Land Image Assessment System (ALIAS) software and algorithm description documentation to the public. Developed through a collaboration between NASA and USGS, the ALIAS supports radiometric and geometric image processing for the Advanced Land Imager (ALI) instrument on board NASA’s Earth Observing-1 (EO-1) satellite. The ALIAS software and documentation can be accessed through the GSFC Open Source website.
