Package org.geotools.ct.proj Description

A set of map projections implementations. Map projections are the process of transforming (longitude,latitude) coordinates in degrees to cartesian coordinates (x,y) in metres. Map projections are implementations of MathTransform2D. This package is for internal use by the org.geotools.ct. package and should not be used directly in normal use.

Most projections expect the following parameters: "semi_major" (mandatory), "semi_minor" (mandatory), "central_meridian" (default to 0), "latitude_of_origin" (default to 0), "scale_factor" (default to 1), "false_easting" (default to 0) and "false_northing" (default to 0). The following table list the projection available in this package together with the extra-parameters expected by some of them.
