Hello Jonathan,
I would at least reccomend to draw the outline during the survey because
it makes it much easier to find your survey points again. I don't know
auriga, so that I can't tell you anything about it but you can also
create polygon plots with therion. An example should be in the wiki, If
you don't find it, please ask as I have that code somewhere on my
computer. If it is from advantage to do the drawing afterwards depends
also on your drawing skills. It is good for therion to have a drawing
that is more or less in scale. An other advantage is that the other
people involved in the survey don't have to wait until you have finished
the perfect drawing.
Regards
Wolfgang
