TRANSCRIPT

  • LatitudeGives north-south location relative to the Equator

  • LongitudeGives east-west location relative to specified meridian

  • Dab = sin(lat a).sin(lat b) + cos (lat a).cos(lat b).cos |lng a - lng b|

  • The Mercator Projectiona cylindrical projection withone standard parallel at the Equator

  • The TransverseMercator Projectiona transverse cylindrical projectionwith one standard parallel alonga specified meridianUsed as the base forzones with an north-southorientation in the StatePlane Coordinate System(SPC) and all zones inthe Universal TransverseMercator System (UTM)

  • Lamberts Conformal Conica conic projectionwith two standard parallelsUsed as the base forzones with an east-westorientation in the State Plane CoordinateSystem (SPC)

  • Meridian(72.5 degrees west longitude)False Easting500,000 meters00Easting (X)Northing (Y)State Plane Coordinate Zone for VermontBase Line(42.5 degrees north latitude)

  • The UTM Coordinate System
