double SRM.BaseSRF_MapProjection.calculateConvergenceOfTheMeridian (  CoordSurf  surf_coord  )  throws SrmException
 

Returns the Convergence of the Meridian in radians at a position on the surface of the oblate spheroid.

Parameters:
surf_coord in: the surface coordinate in this SRF
Returns:
the convergence of the meridian angle (in radians)
Note:
The input surface coordinate must have been created using this SRF.

double SRM.BaseSRF_MapProjection.calculateMapAzimuth (  CoordSurf  src_coord,
CoordSurf  des_coord
)  throws SrmException
 

Returns the map azimuth in radians between two surface coordinates.

Parameters:
src_coord in: the source surface coordinate in this SRF
des_coord in: the destination surface coordinate in this SRF
Returns:
the map azimuth angle (in radians)
Note:
The input surface coordinates must have been created using this SRF.

double SRM.BaseSRF_MapProjection.calculatePointScale (  CoordSurf  surf_coord  )  throws SrmException
 

Returns the point scale at a position on the surface of the oblate spheroid.

Parameters:
surf_coord in: the surface coordinate in this SRF
Returns:
the point scale length (in meters)
Note:
The input surface coordinate must have been created using this SRF.
