Serializable, Formattable, Deprecable, LenientComparable, IdentifiedObject, OperationMethod

Direct Known Subclasses:

ObliqueStereographic, PolarStereographic

@Immutable
public class Stereographic
extends MapProjection

The base provider for "Stereographic" projections. The default implementation uses USGS equations. This is not the provider for EPSG:9809. For the later, use ObliqueStereographic instead.

The math transform implementations instantiated by this provider may be any of the following classes:

• Stereographic
• PolarStereographic
• EquatorialStereographic

The following table summarizes the parameters recognized by this provider. For a more detailed parameter list, see the PARAMETERS constant.

Operation name: Stereographic

Parameter name	Default value
semi_major
semi_minor
roll_longitude	false
central_meridian	0°
latitude_of_origin	0°
scale_factor	1
false_easting	0 metres
false_northing	0 metres

2.4

3.20

Field Detail

CENTRAL_MERIDIAN

@Deprecated
public static final ParameterDescriptor<Double> CENTRAL_MERIDIAN

Deprecated. Invoke PARAMETERS.descriptor(String) instead.

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°.

LATITUDE_OF_ORIGIN

@Deprecated
public static final ParameterDescriptor<Double> LATITUDE_OF_ORIGIN

Deprecated. Invoke PARAMETERS.descriptor(String) instead.

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

SCALE_FACTOR

@Deprecated
public static final ParameterDescriptor<Double> SCALE_FACTOR

Deprecated. Invoke PARAMETERS.descriptor(String) instead.

The operation parameter descriptor for the scale factor parameter value. This parameter is optional as in remotesensing.org. Valid values range is (0 … ∞) and default value is 1.

FALSE_EASTING

@Deprecated
public static final ParameterDescriptor<Double> FALSE_EASTING

Deprecated. Invoke PARAMETERS.descriptor(String) instead.

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

@Deprecated
public static final ParameterDescriptor<Double> FALSE_NORTHING

Deprecated. Invoke PARAMETERS.descriptor(String) instead.

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 group of all parameters expected by this coordinate operation. The following table lists the operation names and the parameters recognized by Geotk. Note that at the opposite of most other map projections, the Scale factor parameter in this group is optional, as documented in the remotesensing.org web site.
