The new file is: MasterCode20YearV2-01.txt. It's in the dropbox! ===== V2-1 Changes ===== There were some issues with bodistkm being rather extreme (i.e., ~6000-8000km):* A single portco, CodeHS had an incorrectly geocoded addresss. Despite being listed as San Francisco, CA, addr2 was "Babraham Research Campus", which Google Maps was incorrectly associating with the village of Babraham in Cambridge, UK. The address for this firm has been manually fixed (the correct address is 1328 Mission St, San Francisco, CA 94103). CodeHS received its first round in 2012 and may achieve an exit.* The remaining extreme values were caused by portcos or firms being located outside of the continental U.S. (i.e., in HI, AK, or PR). When such a firm was paired with a mainland firm, it would have an extreme distance. '''The dataset is now restricted to the continental U.S. The largest distances are now ME-CA pairs or WA-FL pairs, as expected.'''
