ACOLITE is a processor for Landsat (5/7/8) and Sentinel-2 (A/B) imagery developed at RBINS. It allows simple and fast processing for coastal and inland water applications. ACOLITE performs the atmospheric correction by default using the "dark spectrum fitting" approach (Vanhellemont and Ruddick, 2018, Vanhellemont, 2019) but can be configured to use the "exponential extrapolation" (Vanhellemont and Ruddick, 2014, 2015, 2016).
Features include the extraction of rectangular regions of interest (defined by bounding coordinates), calculation of reflectance derived parameters, and the generation of RGB images before and after atmospheric correction. Products are output as geolocated datasets in a NetCDF file and can be exported as GeoTIFF and PNG images.
The dark spectrum fitting is described in the following publications:
