ACOLITE is a stand-alone version of the IDL processing for Landsat-8 and Sentinel-2 developed at RBINS.
It allows simple and fast processing of L8 and S2 images for marine and inland water applications. Features include generation of RGB images before (TOA) and after (RCO) Rayleigh correction, atmospheric correction of water bodies and extraction of rectangular regions of interest (defined by bounding coordinates). Level 2 outputs are marine reflectance (ρw=Rrs⋅π) and multiple scattering aerosol reflectance (ρam), that can be saved as PNG maps and geolocated datasets in a NCDF (NetCDF) file. An IDL runtime is included in the distribution and the application can be run without software license.
The atmospheric correction is image based and needs no external inputs. The aerosol type (ε) can be fixed and automatically determined for each scene, or can vary per pixel. Some details and concepts of the processor can be found in the references below.
