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.
I'm not sure what environment you're working in, but because UTM zones are referenced to a unique central meridian, the longitude of a point should be within +/- three degrees centered on the central meridian of your target UTM zone.
