Field Detail

CENTRAL_MERIDIAN

public static final ParameterDescriptor<Double> CENTRAL_MERIDIAN

The operation parameter descriptor for the central meridian parameter value. This parameter is mandatory. Valid values range is [-180 … 180]° and default value is 0°.

TODO:

According the remote-sensing web site, the OGC name for this parameter is "longitude_of_center". However the spatial-reference web site said "central_meridian", which was also the usage in GeoTools 2.x and is preserved for now.

LATITUDE_OF_ORIGIN

public static final ParameterDescriptor<Double> LATITUDE_OF_ORIGIN

The operation parameter descriptor for the latitude of origin parameter value. This parameter is optional. Valid values range is [-90 … 90]° and default value is 0°.

TODO:

According the remote-sensing web site, the OGC name for this parameter is "latitude_of_center". However the spatial-reference web site said "latitude_of_origin", which was also the usage in GeoTools 2.x and is preserved for now.

STANDARD_PARALLEL_1

public static final ParameterDescriptor<Double> STANDARD_PARALLEL_1

The operation parameter descriptor for the first standard parallel parameter value. This parameter is optional - if omitted, it takes the same value than the one given for LATITUDE_OF_ORIGIN. Valid values range is [-90 … 90]°.

STANDARD_PARALLEL_2

public static final ParameterDescriptor<Double> STANDARD_PARALLEL_2

The operation parameter descriptor for the second standard parallel parameter value. This parameter is optional - if omitted, it takes the same value than the one given for STANDARD_PARALLEL_1. Valid values range is [-90 … 90]°.

FALSE_EASTING

public static final ParameterDescriptor<Double> FALSE_EASTING

The operation parameter descriptor for the false easting parameter value. This parameter is mandatory. Valid values range is unrestricted and default value is 0 metre.

FALSE_NORTHING

public static final ParameterDescriptor<Double> FALSE_NORTHING

The operation parameter descriptor for the false northing parameter value. This parameter is mandatory. Valid values range is unrestricted and default value is 0 metre.

PARAMETERS

public static final ParameterDescriptorGroup PARAMETERS

The parameters group.
