ACOLITE version 20141107.0 was released after the 2015 Ocean Optics conference in Portland, Maine.
Updates since 20140722.0:
- more efficient (accurate?) calculation of lon/lat from GeoTIFF tags and better crop positioning
- crop when rather than after reading GeoTIFF files
- mapping now uses UTM coordinates and no additional reprojection to equirectangular projection (should fix REBIN issue)

ACOLITE Features include:
- Generation of Top of Atmosphere (TOA) and Rayleigh corrected (RCO) RGB images.
- Atmospheric correction and L2 map and NetCDF generation.
- Processing of a full tile or cropped region.
L2 products include marine reflectance (rhow = pi x Rrs) in the visible and NIR wavebands (443, 483, 561, 655 and 865 nm), and a multiple scattering aerosol reflectance (rhoam) in the NIR band. The default atmospheric correction is Vanhellemont and Ruddick (2015), but a switch is included for using Vanhellemont and Ruddick (2014).
