| LambertConformal | | abstract public class LambertConformal extends MapProjection (Code) | | Lambert Conical Conformal Projection. Areas and shapes are deformed
as one moves away from standard parallels. The angles are true in
a limited area. This projection is used for the charts of North America.
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).
