This plugin was created to mimic the behaviour from Google Earth© as illustrated below. We only choose to display information in a widget instead of a dialog.
We just want to draw a temporary start point, draw a end point and then display the resulting distance and azimuth. At the moment, we don’t give the option to save the line drawing.
You just need to install it through the menu Plugins > Manage and Install Plugins... and choose Azimuth Measurement.
warning
You need to tick Show also Experimental plugins in Settings lateral tab or you will not see the plugin.
You just have to follow below demonstration to understand how to use the plugin.

For the azimuth calculation, we choose to reuse pygc, a MIT licensed Python azimuth calculation library (so we can sublicence it in the GPL plugin code). We removed the dependency to Numpy Python package from it.
Depending of your requirements, you may prefer using other plugins, more complex and for other use cases:
You can open an issue on the repository or drop us an email at contact(at)webgeodatavore.com
We also do QGIS support for users and Python development in France. You can see more at our official website.
