public abstract class LambertConformal extends MapProjection
This implementation provides transforms for three cases of the lambert conic conformal projection:
Lambert_Conformal_Conic_1SP (EPSG code 9801)Lambert_Conformal_Conic_2SP (EPSG code 9802)Lambert_Conic_Conformal_2SP_Belgium (EPSG code 9803)Lambert_Conformal_Conic - An alias for the ESRI 2SP case
that includes a scale_factor parameter
For the 1SP case the latitude of origin is used as the standard parallel (SP). To use 1SP with
a latitude of origin different from the SP, use the 2SP and set the SP1 to the single SP. The
standard_parallel_2" parameter is optional and will be given the same value as
"standard_parallel_1" if not set (creating a 1 standard parallel projection).
