I did not play much with this format but it does support xyz points. I would import the gpx file, save as .shp. Use a Dem like NASADEM to get the elevations (you have multiple tools and plugins that can make a point sampling from a raster) and then save to gpx.</div><div><br></div><div>You could create a model to accelerate the process. You can then batch this model in “processing”. </div><div><br></div><div><a href="https://gdal.org/drivers/vector/gpx.html">https://gdal.org/drivers/vector/gpx.html</a></div><div><br></div><div>Look for gpx or gps in the plugins, you will probably find interesting tools there.<br><br><div dir="ltr">Nicolas Cadieux<div><a href="https://gitlab.com/njacadieux">https://gitlab.com/njacadieux</a></div></div><div dir="ltr"><br><blockquote type="cite">Le 25 janv. 2022 à 09:03, APM <apschwimmer@apmland.de> a écrit :<br><br></blockquote></div><blockquote type="cite"><div dir="ltr"><span>Dear List,</span><br><span></span><br><span></span><br><span></span><br><span>is it possible to add elevation data to gpx files with Qgis?</span><br><span></span><br><span>I have a high amount of gpx-files and would have to add the data's in a batch.</span><br><span></span><br><span></span><br><span></span><br><span>Thank you!</span><br><span></span><br><span></span><br><span></span><br><span>Kind regards</span><br><span></span><br><span></span><br><span>Piet</span><br><span></span><br><span>_______________________________________________</span><br><span>Qgis-user mailing list</span><br><span>Qgis-user@lists.osgeo.org</span><br><span>List info: https://lists.osgeo.org/mailman/listinfo/qgis-user</span><br><span>Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user</span><br></div></blockquote></div></div></body></html>
