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.
Also since a Transverse Mercator projection results in extreme distortion in polar areas, the UTM zones are limited to 80Â°S and 84Â°N latitudes. Polar regions (below 80Â°S and above 84Â°N) use the UPS - Universal Polar Stereographic coordinate system based on the Polar Stereographic projection.
