Log speed

Open deepakkoirala opened this issue 5 years ago • 8 comments

Can we implement actual the speed in the gpx log file. If we can have it, it would be great. I am interested in logging the speed that I was traveling for that specific time, lat and long.

It would save a lot of time to process the data again to get the speed on which we were traveling. The application is already displaying the speed data in the UI.

It would be a great feature to have it.

For that we would need to have an extension to GPX. The first version of the GPX file format contains a speed attribute, but was removed in v1.1, which is the current version.

@vincentneo How do we have the speed then in the log? I am pushing this gpx file to a remote server for analytics and I need the speed.

This feature would really helped everyone.

The correct way towards doing it would require drafting a XML schema to extend this GPX format, to include whatever attributes that are to be wished for.

The not so correct way would be to just tag it under extensions without a schema. Technically an incorrect way towards approaching XML stuff, as far as I believe, but a lot easier?

For me this is also a feature that I have missed sometimes.

@vincentneo does CoreGPX already support extensions?

@merlos Yes, CoreGPX does support extensions, just that is a particularly less tested out, more buggy part of it.

@merlos @vincentneo any possibilities?

I really like GPX tracker but also really miss the speed log. Even the smallest change would help me, like displaying the max speed and average speed. Can someone please add some kind of speed logging? Just start small by adding the max speed, then expanding to average speed and then more and more detailed speed logging.
