Longitudes should be given modulo 360deg[edit]

Or is there a reason they are given in raw form? --Dschwen 14:18, 24 March 2011 (UTC)

Coordinate systems for non-earth planets can use the extended range [-360,360] due to convention. If abs(lon) >= 1000 or abs(lat) >= 100, we assume that the decimal point was misplaced and shifts appropriately rather than using a modulo, since the majority of cases are input errors. I may consider adding more conditions so the range are within -90 <= lat <= 90 and -180 <= lon <= 180. Dispenser
