GPX speed data

[jethro]

Hi, some GPX files I import have speed data embedded. Some of the analysis screens for a gpx file use this data so osmand must be speed aware.

However I can't seem to add speed while creating a route with the app. Is this/should this be possible?

The GPX schema does not have a speed component.  So I would assume that speed awareness is calculated from time and distance between points, rather than found directly in the data.

GPS = Global Positioning System

Positioning
what is the meaning of this word ? Where i am now.

what info i need for this ?
1. date
2. time
3. location data = coordinates (2D) and elevation (3D)

Those info are result from the GNSS receiver we have into a device, like a PND or smartphone. All the others are generated - calculated from the running software of the devices we have.
