latitude2gpx's Issues

Latitude format has changed

This tool doesn't work anymore because the latitude format has changed. They still give us KML but in the form of tracks with a start and end time and a series of points.

This is not as useful as the old format or each point + time.

I'm not sure how to fix, we could interpolate the times of the track each point but I'm not sure that'll be accurate enough.

I see you've forked @martinluck - are you planning on fixing it? I'm happy to take changes back from your repo if just add you as a contributor here.
