Map arcs crossing the international date line

[kasei]

Not sure if it's possible to fix this based on the libraries being used, but when mapping a photo sequence that crosses the international dateline, you end up with a map that has an unsightly horizontal line running across the entire width.

Any way to suppress that?

wow that's quite some traveling :) Indeed I expected this problem. I'm gonna add some fake data to my dataset and see if I can find a way to handle it (I guess it should be skipped or truncated to handle the specific view of the world I'm using). Otherwise if you don't mind sending me your reduced dataset locations (as a csv or RData file), that would be great.

Sure. Can I email it to you? I've got the output of exiftool ready to go. If you'd prefer the cvs or R data, can you guide me to the right R commands to emit that?

save(picsLocationsReduced, file = "dataPicsReduced.RData") email to altini.marco@gmail.com ill see what i can do later tonight, thanks!

please give it a try now. There should be no wrong line plotted even if you cross the dateline

Works great, thanks!
