[Qgis-user] GPX group, add field "name" from track layer to attribut table point layer

[APM]

Dear Greg,


thank you for your kindly answer!

Meanwhile I found a solution for my problem.

I can use the menu "Extract Vertices" to solve my problem.

This creates a usable point layer with the needed "name" field.


The "tracklogs" you mentioned are GPS-Tracks from a GPS-Device?

I use the same for my map.


But anyway, I'll check your remarks about the bounding boxes!


Kind regards


Piet
