ATIG Members-

The attached paper documents an algorithm to plot horizon points as observed from an orbiting location onto an Earth surface map.  It is similar to a companion method coplotting the terminator delimiting Earth's nightside on a surface map (ref. ATIG_109 at http://www.aiaahouston.org/adamo_astrodynamics/).  As always, questions and comments on this material are invited.
