I know at least two students who work with night-lights for ther Master's Thesis. I'll forward them this e-mail. If it's worth anything, a related add-on: <https://trac.osgeo.org/grass/browser/grass-addons/grass7/imagery/i.nightlights.intercalibration?order=name> Inter-calibration has been an important subject for the DMSP OLS instruments. Would be nice to learn more about newer developments, and, if possible, expand the addon. > I am first thinking of trying to use this to spatiotemporaly interpolate > ward-scale population between (10 yr) interval census years.

The add-on, given we mean the same one, is complete in the sense that the three main models, integrated there-in, do what they intend to do. Up until someone identifies any errors :-). Any kind of assistance would, then, be more than welcome.
