Geomatics 2550 Clemson Exam Question with complete solution graded A+

What does UTM stand for? - Universal Traverse Mercator UTM width and X coordinate - Each zone is 6 degrees wide with an x coordinate of 500 km or 500,000 m assigned to central meridian Easting values increase when... - Values are to the east (right) of the central meridian. example: SC central meridian is 500,000 m (by definition) 121,000 east of the central meridian has an easting of 500,000 + 121,000 = 621,000. Easting values decrease when... - Values are to the west (left) of the central meridian. example: SC central meridian is 500,000 m (by definition) 90,000 m west of the central meridian has an easting of 500,000 - 90,000 = 410,000. Northing - What UTM zones do the US fall within - 10-19 How many UTM zones are there - 60 (360 degrees / 6 degrees each) All states follow one of the two types of projections. What are the two types? - 1. Lambert conformal conic 2. Transverse Mercator What type of states typically use Lambert projections? - Wide states (Nebraska, NC) (cone shaped) What type of states typically use Transverse projections? - Tall states (Georgia) (cylinder shapes)Some states use both Lambert and Transverse projections - ex: Florida The lone exception of the Lambert or Transverse projection is... - Alaska, which uses an oblique Mercator projection
