[Qgis-user] Digitizing points with azimuth and distance

There are two possible solutions.

1. Currently the Create Shapes, Line of bearing tool just creates a
geodesic line between two points. It would be real easy to have it create a
destination point on a separate layer. The input to this tool is a point or
table layer with the beginning and destination points or the beginning
point and then you use the default settings within the dialog box for the
azimuth and distance.

2. I think what you are asking is to start with a point layer in edit mode.
Click on the map, have a dialog box pop up, enter the distance and azimuth,
click on OK, and it adds the destination point to the selected layer. Would
this be a suitable solution? Would you also want to add the begging point
to the same layer? It could be optional with a check box.

Are geodesic distance calculations what you are looking for or simple
euclidean distances? Shape Tools works with geodesic distances similar to
Google Earth.
