I was mapping an area in Namibia and also tracked a lot of paths on my way with my Garmin device… so I thought it would be nice to see height differences in my area (esp. interesting in the raining-season… where is the water going to be?)… but then I came to notice, that QGIS does not support the Z-Coordinate when using Shape-Files. I have currently all the data stored as a GPX file, how can I get QGIS (1.8) to recognize the Z-Coordinate?
And yes my device supports the tracking of height, that's for sure 🙂

Importing the GPX file with
add vector layer, and selectingtrack_pointslayer, you get all collected height data inelefield. Saving that to shapefile, it is possible to change color according to theelevalue, or create raster grids etc.
