Haven't registered yet? The North American Association of Summer Sessions (NAASS) is an association of deans, directors and administrators of college and university summer programs located throughout the United States, Canada, and Mexico.
UTM zones are numbered 1 through 60, starting at the international date line, longitude 180Â°, and proceeding east. Zone 1 extends from 180Â° W to 174Â° W and is centered on 177Â° W. Each zone is divided into horizontal bands spanning 8 degrees of latitude.
For example, 45 N 89.9 W and 45 N 90.1 W are only about 15 km apart on the ground, but their UTM easting coordinates are 271428.8E and 728571.2 E. Even though it's not technically correct, it's sometimes a lot more useful to extend the grid across the zone boundary.
