Interface GeographicCRS

All Superinterfaces:: CoordinateReferenceSystem, Info, ReferenceSystem

public interface GeographicCRS
extends CoordinateReferenceSystem

A coordinate reference system based on an ellipsoidal approximation of the geoid; this provides an accurate representation of the geometry of geographic features for a large portion of the earth's surface.

Used with CS type(s)
`Ellipsoidal`

Version:

Abstract specification 2.0

Author:

ISO 19111, OpenGIS® consortium

UML identifier (abstract type): SC_GeographicCRS

REVISIT OPEN ISSUE (a GeoAPI comment)

OGC document 01-009 defines a getWGS84ConversionInfo() method. A getWGS84Parameters() method was also defined in the datum. I see no equivalent in this ISO 19111 specification.

Method Summary
`EllipsoidalCS`	`getCoordinateSystem()` Returns the coordinate system, which must be ellipsoidal.
`GeodeticDatum`	`getDatum()` Returns the datum, which must be geodetic.

Methods inherited from interface ReferenceSystem
`getScope, getValidArea`
