Transverse Mercator Map Projection Point Scale Equations

• For the Transverse Mercator map projection

associated with an ERM the point scale k is given by:

where ?=(longitude-origin longitude), ? is the

geodetic latitude and D2 , D4 and D6 are

complex functions of the ERM eccentricity and

geodetic latitude.

• This series representation has been truncated from

an infinite series but is accurate enough for the

experiment.
