	Longitude shows your location in an east-west direction, relative to the Greenwich meridian. Places to the east of Greenwich (such as Middle East, India and Japan) have longitude angles up to 180 degrees east. Places to the west of Greenwich (such as the Atlantic and North and South America) have angles up to 180 deg west. For inputting to the satellite dish pointing calculator, longitude west figures need to be input as negative numbers.

			== Latitude or longitude? ==

			FYI:

			Latitude
			Latitude is used to express how far north or south you are, relative to the equator. If you are on the equator your latitude is zero. If you are near the north pole your latitude is nearly 90 degrees north. If you are near the south pole your latitude is almost 90 degrees south.

			Longitude
			Longitude shows your location in an east-west direction, relative to the Greenwich meridian. Places to the east of Greenwich (such as Middle East, India and Japan) have longitude angles up to 180 degrees east. Places to the west of Greenwich (such as the Atlantic and North and South America) have angles up to 180 deg west. For inputting to the satellite dish pointing calculator, longitude west figures need to be input as negative numbers.

	Just for comparison, I got a global land percentage of 31.224.. The way I did it however also suffers from some mapping distortions, although not so big.. So 29.44 is probably not to wrong..

			: After scraping out a heap of integer based calculations my figures vary a bit, but they're still fairly close to what they were. I think my main problem is correctly determining when polygons cross the prime meridion and loop around to the other side: Get that wrong, and certain polys will be way out in terms of accuracy.
