use spatial data already present in files
post replylog2map: Upload your Log and Look at Pretty Interactive Equidistant Azimuthal Maps of your Contacts from root_127-0-0-1 via /r/amateurradio sent 20 minutes ago As long as you're parsing ADIF, the GRIDSQUARE QSO field should provide finer resolution than ctydat, particularly if a 4-character or finer Maidenhead locator is provided. contextfull comments (17)reportblock usermark unreadreply n1ywb[S] 1 point a minute ago That's a good idea. ADIF also has lat/lon fields which I should probably check if those are populated before I bother to look up the call. I suppose if your log program connects to qrz already it might pre-populate those and save me the georeferencing step. Some cabrillo files might have grid square info if it's part of the contest exchange, I'll have to check that also. One of the obvious downsides to georeferencing after the fact is that hams move around, esp for VHF contests and the like..
