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.
Thus a degree of longitude is 69 miles = 364320 feet, and 0.1 degree is 36432 feet, and so on. Take a look at the table in the article Understanding GPS coordinates to understand this concept better. Hopefully, more and more commercial GPS units will use this degree decimal system in the future.
