12.4.4.9 LinearCS

element name=LinearCS type=gml:LinearCSType substitutionGroup=gml:AbstractCoordinateSystem complexType name=LinearCSType complexContent extension base=gml:AbstractCoordinateSystemType complexContent complexType gml:LinearCS is a one-dimensional coordinate system that consists of the points that lie on the single axis described. The associated coordinate is the distance — with or without offset — from the specified datum to the point along the axis. A LinearCS shall have one gml:axis property element. EXAMPLE Usage of the line feature representing a pipeline to describe points on or along that pipeline. NOTE gml:LinearCS can only be used for simple continuous linear systems. Linear Reference Systems LRS, particularly as applied to the transportation industry, are specified in ISO 19133 and are not implemented by this International Standard.

12.4.4.11 UserDefinedCS

element name=UserDefinedCS type=gml:UserDefinedCSType substitutionGroup=gml:AbstractCoordinateSystem complexType name=UserDefinedCSType complexContent extension base=gml:AbstractCoordinateSystemType complexContent complexType gml:UserDefinedCS is a two- or three-dimensional coordinate system that consists of any combination of coordinate axes not covered by any other coordinate system type. A UserDefinedCS shall have two or three gml:axis property elements; the number of property elements shall equal the dimension of the CS. Copyright © 2007 Open Geospatial Consortium, Inc. All Rights Reserved. 115 EXAMPLE A multilinear coordinate system which contains one coordinate axis that may have any 1D shape which has no intersections with itself. This non-straight axis is supplemented by one or two straight axes to complete a 2 or 3 dimensional coordinate system. The non-straight axis is typically incrementally straight or curved.

element name=SphericalCS type=gml:SphericalCSType substitutionGroup=gml:AbstractCoordinateSystem complexType name=SphericalCSType complexContent extension base=gml:AbstractCoordinateSystemType complexContent complexType gml:SphericalCS is a three-dimensional coordinate system with one distance measured from the origin and two angular coordinates. NOTE It should not be confused with an ellipsoidal coordinate system based on an ellipsoid degenerated into a sphere. A SphericalCS shall have three gml:axis property elements.
