QGIS TrackProfile2Web Plugin

This plugin allows you to select a line layer with Z values and to create an interactive elevation profile embedded within QGIS itself:

The workflow is very simple:

1. select a line layer loaded in QGIS from the combobox
2. choose the tile map
3. optionally change some customization
4. click on the Update Preview button
5. that's it! Just navigate in the map and hover the mouse on the profile to see the position on the map

If you want you can export the map as a single html file or as html + geojson. The results can be easily embedded in a web page.
