[GRASS-user] OFF-TOPIC - Earth Curvature in profiles

[Carlos "Guâno" Grohmann]

Sorry for the OT, but can anyone point me some reference (paper, web,
etc) that explains how can I draw a topographic profile using the
Earth´s curvature? I am thiking about the output of r.profile (ascii,
distance from origin + elevation), in a section of about 3000 km, with
a vertical exaggeration of about 200 times.

tks!

Carlos
