PointType, Point Geometric primitives 0-dimensional

62 Copyright © 2007 Open Geospatial Consortium, Inc. All Rights Reserved. complexType element name=Point type=gml:PointType substitutionGroup=gml:AbstractGeometricPrimitive A gml:Point is defined by a single coordinate tuple. The direct position of a point is specified by the gml:pos element which is of type gml:DirectPositionType. gml:Point implements ISO 19107 GM_Point see D.2.3.3 and ISO 19107:2003, 6.3.11. The use of the element “coordinates” is deprecated. Use “pos” instead.

10.3.2 PointPropertyType, pointProperty

complexType name=PointPropertyType sequence minOccurs=0 element ref=gml:Point sequence attributeGroup ref=gml:AssociationAttributeGroup attributeGroup ref=gml:OwnershipAttributeGroup complexType element name=pointProperty type=gml:PointPropertyType A property that has a point as its value domain may either be an appropriate geometry element encapsulated in an element of this type or an XLink reference to a remote geometry element where remote includes geometry elements located elsewhere in the same document. Either the reference or the contained element shall be given, but neither both nor none. This property element either references a point via the XLink-attributes or contains the point element. pointProperty is the predefined property which may be used by GML application schemas whenever a GML feature has a property with a value that is substitutable for gml:Point.

10.3.3 PointArrayPropertyType, pointArrayProperty

complexType name=PointArrayPropertyType sequence minOccurs=0 maxOccurs=unbounded element ref=gml:Point sequence attributeGroup ref=gml:OwnershipAttributeGroup complexType element name=pointArrayProperty type=gml:PointArrayPropertyType gml:PointArrayPropertyType is a container for an array of points. The elements are always contained inline in the array property. Referencing geometry elements or arrays of geometry elements via XLinks is not supported. This property element contains a list of point elements. pointArrayProperty is the predefined property which may be used by GML application schemas whenever a GML feature has a property with a value that is substitutable for a list of points.

10.4.1 AbstractCurveType, AbstractCurve

complexType name=AbstractCurveType abstract=true complexContent Copyright © 2007 Open Geospatial Consortium, Inc. All Rights Reserved. 63 extension base=gml:AbstractGeometricPrimitiveType complexContent complexType element name=AbstractCurve type=gml:AbstractCurveType abstract=true substitutionGroup=gml:AbstractGeometricPrimitive gml:AbstractCurveType is an abstraction of a curve to support the different levels of complexity. The curve may always be viewed as a geometric primitive, i.e. is continuous. The gml:AbstractCurve element is the abstract head of the substitution group for all continuous curve elements.

10.4.2 CurvePropertyType, curveProperty

complexType name=CurvePropertyType sequence minOccurs=0 element ref=gml:AbstractCurve sequence attributeGroup ref=gml:AssociationAttributeGroup attributeGroup ref=gml:OwnershipAttributeGroup complexType element name=curveProperty type=gml:CurvePropertyType A property that has a curve as its value domain may either be an appropriate geometry element encapsulated in an element of this type or an XLink reference to a remote geometry element where remote includes geometry elements located elsewhere in the same document. Either the reference or the contained element shall be given, but neither both nor none. This property element either references a curve via the XLink-attributes or contains the curve element. curveProperty is the predefined property which may be used by GML application schemas whenever a GML feature has a property with a value that is substitutable for gml:AbstractCurve.

10.4.3 CurveArrayPropertyType, curveArrayProperty

complexType name=CurveArrayPropertyType sequence minOccurs=0 maxOccurs=unbounded element ref=gml:AbstractCurve sequence attributeGroup ref=gml:OwnershipAttributeGroup complexType element name=curveArrayProperty type=gml:CurveArrayPropertyType A container for an array of curves. The elements are always contained inline in the array property. Referencing geometry elements or arrays of geometry elements via XLinks is not supported. This property element contains a list of curve elements. curveArrayProperty is the predefined property which may be used by GML application schemas whenever a GML feature has a property with a value that is substitutable for a list of curves.
