The GPX file contains a number of fields whose contents you can see / <br>
access in the layer's Attribute Table<br>
right-click on layer and choose Open Attribute Table<br>
<br>
However, these are only the extra fields in the GPX records but<br>
NOT including the x,y coordinates (Long,Lat)<br>
<br>
To access the later, use the Field Calculator<br>
select the layer<br>
click on Open Field Calculator icon (Abaccus) in the menu bar<br>
which is next to the Open Attribute Table icon in menu, or<br>
in Processing > GDAL > Vector Table > Field Calculator<br>
<br>
create new fields, called Lat and Long, as decimal numbers<br>
and enter the expression $X or $Y (see Geometry > for details)<br>
When you click OK, the new fields will be appended and filled in<br>
with the right values.<br>
<br>
You can then access them in the layer's Attribute Table.<br>
<br>
With those 2 extra fields you essentially have access to everything<br>
that was recorded in the GPX file.<br>
<br>
You can also use Field Calculator to add more fields and populate<br>
them with calculation results.<br>
<br>
As an aside, Field Calculator cannot create new fields in the GPX<br>
file; instead it creates them as temporary virtual fields.<br>
<br>
A better approach is to first save the data in a shape file<br>
right-click on layer, choose Export > Save selected features<br>
then open that file instead of the original GPX.<br>
Field Calculator will add new fields to that format.<br>
<br>
Cordially,<br>
