Hi Calvin:
An interesting question. Another consideration is the coordinate system
for your project. If it is a projected system, then you should consider
convergence which is the angle between true north and grid north. In a
common example, UTM zone meridians are the center of each zone

Phil,
The Shape Tools plugin has an "Azimuth distance digitizer" and for what you are talking
about an "Azimuth distance sequence digitizer". With the latter function you click on a
starting location and then give a list of azimuth,
Phil,
The Shape Tools plugin has an "Azimuth distance digitizer" and for what you
are talking about an "Azimuth distance sequence digitizer". With the latter
function you click on a starting location and then give a list of azimuth,
distance sequences. I have used this for old surveys like this.
The "Azimuth and Distance Plugin" might meet your needs. It accepts
bearings/azimuths from north increasing clockwise.

Hello,
I am trying to digitise a series of old gold lease "portion plans" produced in
the 1880s in Australia by a mining surveyor using a compass and chain. The data
for each gold lease includes a table of 1) compass bearings in degrees and 2)
distance measurements in links (0.2 m) for each
