Finding coordinates on the circumference of a circle [message #44829]

Hello group-

I am preparing flight lines over a CO2 flux tower in Canada. I need to
find the geographic coordinates of several points located on the
circumference of a circle defined around the tower. The points are
equally spaced (10 degrees), starting at 0 degrees (north) and
incrementing clockwise. I want to do this for circles of different
radii (10 km, 13 km, etc.). I need these coordinates in either WGS84 or
NAD83.

I found 'compass.pro' and 'findrng.pro', routines that find ranges and
azimuths for given points (lat/lon) around a center location. I would
like the opposite: find locations around a central point from arrays of
azimuths and ranges.

Does anybody know something that could help me?

Cheers!

Guillaume
