I've put together a simplistic COGO utility for translation bearing-distance
measurements (like legal descriptions) to coordinate pairs. It will also
do the reverse operation given a set of input coordinates. I haven't
added it to CVS yet, as I don't know it's very useful in its current
form. For those who'd like to try it out, see
http://pweb.jps.net~/egm2/grass/cogo/m.cogo/index.html -- links to the
program files are at the bottom of the page.
It doesn't currently generate vectors, but its output can be piped to
s.in.ascii like:
GRASS> m.cogo -l input=cogo.dat coord=702672,4287043 | s.in.ascii sites=cogo
Generally, it needs a starting coordinate for either forward or reverse
operations (otherwise all calculations begin from 0,0).
I'd like to make a more useful variant that will generate vectors --
similar to v.transect. But, I'm not familiar enough with common
survey file formats. The current input format is also a bit rigid...
