<H4>EC</H4>
<PRE>
 Projection     : Equidistant Conic
 Also known as  : Simple Conic or Conic
 General class  : conic
 Characteristics: equidistant
 Earth model    : ellipsoid or sphere
</PRE>
Defining the MAPUNITS (Format A or B):
<P>
<PRE>
 MapUnits &quot;ec&quot;       ! Standard name
 MapUnits &quot;ec e0&quot;    ! Standard name and ellipsoid
</PRE>
Other parameters (Format A, one standard parallel):
<P>
<PRE>
 TrueOriginLongitude &quot;central_meridian&quot;       ! Required -+- True origin
 TrueOriginLatitude  &quot;latitude_of_origin&quot;     ! Required /
 1stStandardParallel &quot;1st_standard_parallel&quot;  ! Required
 FalseEasting        &quot;false_easting&quot;          ! Optional, default is zero
 FalseNorthing       &quot;false_northing&quot;         ! Optional, default is zero
</PRE>
Other parameters (Format B, two standard parallels):
<P>
<PRE>
 TrueOriginLongitude &quot;central_meridian&quot;       ! Required -+- True origin
 TrueOriginLatitude  &quot;latitude_of_origin&quot;     ! Required /
 1stStandardParallel &quot;1st_standard_parallel&quot;  ! Required
 2ndStandardParallel &quot;2nd_standard_parallel&quot;  ! Required
 FalseEasting        &quot;false_easting&quot;          ! Optional, default is zero
 FalseNorthing       &quot;false_northing&quot;         ! Optional, default is zero
</PRE>
Possible errors:
<P>
<PRE>
 E332, &quot;Equal latitudes for st. parallels on opposite sides of 
        equator &quot; - Error occurred in initializing the projection.
