[Qgis-user] Generate the bearing in the attribute table

[C Hamilton]

There is a somewhat obscure feature to the Shape Tools plugin
<https://plugins.qgis.org/plugins/shapetools/> that will calculate the
distance of each segment in a line and it also calculates the azimuth as
well, but you will not automatically see it as it is in the attribute
table. I don't know if it will work for you or not.

Once you install the Shape Tools plugin, run this algorithm from the QGIS
menu "Vector->Shape Tools->Geodesic measurement layer". Make sure "Measure
total length rather than each line segment" is NOT checked then run it. It
will display measurements of each segment in your lines, but if you open up
the attribute table, you will see a "heading_to" attribute which is your
azimuth. You could right-mouse click on your new layer and change the label
to the heading_to attribute to have it displayed on the map. I probably
should add a feature to that algorithm that allows you to display either
the distance or azimuth.

Regards,

Calvin
