Presentation transcript:

Latitude Gives north-south location relative to the Equator

Longitude Gives east-west location relative to specified meridian

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

The Mercator Projection a cylindrical projection with one standard parallel at the Equator

The Transverse Mercator Projection a transverse cylindrical projection with one standard parallel along a specified meridian Used as the base for zones with an north-south orientation in the State Plane Coordinate System (SPC) and all zones in the Universal Transverse Mercator System (UTM)

Lambert’s Conformal Conic a conic projection with two standard parallels Used as the base for zones with an east-west orientation in the State Plane Coordinate System (SPC)

State Plane Coordinate Zone for Vermont Meridian (72.5 degrees west longitude) Northing (Y) False Easting 500,000 meters Base Line (42.5 degrees north latitude) Easting (X)
