Thanks Simon In your first comment, you say
"A meridian is a line of constant longitude passing between the poles and through a given place on the earth's surface. That is, meridians traverse from east to west like the lines of longitude. " See: http://www.firefightermath.org/index.php?option=com_content&view=article&id=61&Itemid=75 "Longitude lines (called meridians) run north and south and circle the planet from pole to pole." Or: http://www.rmg.co.uk/explore/astronomy-and-time/astronomy- facts/history/the-prime-meridian-at-greenwich "A meridian is a north-south line selected as the zero reference line for astronomical observations. " Based on this the proposal in your last comment is incorrect. Let me know your thoughts. Feel free to propose a new improved sentence.
