[Qgis-user] user defined format for new bearing tool?

[C Hamilton]

Richard,

The Shape Tools plugin has a geodesic measure tool
<https://github.com/NationalSecurityAgency/qgis-shapetools-plugin#--geodesic-measure-tool>
that in addition to distance, displays the bearing to and bearing from two
points. Right now it just displays in decimal degrees, but it wouldn't be
difficult to add a setting option to display in a DMS format. Give it a try
and let me know whether you think it would be helpful to include a DMS
format.

Thanks,

Calvin
