Markus, ALL
I got interested in the m.cogo module, but I was unable to follow the link.
It seems that archive.org doesn't have that page anymore.
Google was unable to find m.cogo outside GRASS home pages or list archives.
I am looking for it in the cvs tree.

It was a sorry mistake I made.
I just get back from archive.org and it seems that the correct url would be:
http://web.archive.org/web/*/http://pweb.jps.net/~egm2/

I have updated m.cogo today to GRASS 6 and can add that to
the 6.1-CVs if there is interest.

Hi,
I have found m.cogo on my laptop and added it with a few small
C fixes to 6.1-CVS.
It would be cool to add the interactive code from r.profile
to it to easily draw a line into a map and then receive it's
angle... volunteer welcome.

does it use geodesic for lat/lon locations? Angle to point away loses
meaning after the distance grows big enough that the shape of the Earth
matters.. but I guess this isn't what the module is for?

If I recall correctly from my surveying classes, the maximum distance
one could consider a flat earth is around 12 or 16 km. I mean, the
surveying validity (sp??) is a square with 12 (or 16) km sides.
Maybe a warning could be added to m/v.cogo regarding these issues.

I dunno - didn't check the code in details.
Of course a nice-to-have feature.

A good map projection can limit the damage. In the US, State Plane
projections are designed for accurate surveying work for fairly large
parts of a state (that is 100+ km). If I recall correctly the
Washington State Plane North projection (my home state) has a maximum
error of only a few cm over its target domain.
