EC

 Projection     : Equidistant Conic
 Also known as  : Simple Conic or Conic
 General class  : conic
 Characteristics: equidistant
 Earth model    : ellipsoid or sphere

Defining the MAPUNITS (Format A or B):

 MapUnits "ec"       ! Standard name
 MapUnits "ec e0"    ! Standard name and ellipsoid

Other parameters (Format A, one standard parallel):

 TrueOriginLongitude "central_meridian"       ! Required, for True origin
 TrueOriginLatitude  "latitude_of_origin"     ! Required, for True origin
 1stStandardParallel "1st_standard_parallel"  ! Required
 FalseEasting        "false_easting"          ! Optional, default is zero
 FalseNorthing       "false_northing"         ! Optional, default is zero

Other parameters (Format B, two standard parallels):

 TrueOriginLongitude "central_meridian"       ! Required, for True origin
 TrueOriginLatitude  "latitude_of_origin"     ! Required, for True origin
 1stStandardParallel "1st_standard_parallel"  ! Required
 2ndStandardParallel "2nd_standard_parallel"  ! Required
 FalseEasting        "false_easting"          ! Optional, default is zero
 FalseNorthing       "false_northing"         ! Optional, default is zero

Possible errors:

 E332, "Equal latitudes for st. parallels on opposite sides of 
        equator " - Error occurred in initializing the projection.
