GML4RAILML:posList/3.2

Automatic Schemaexport for Element posList

Autoexport from the XML-Schema for element GML4RAILML:posList of railML® version 3.2
Documentation	posList instances (and other instances with the content model specified by DirectPositionListType) hold the coordinates for a sequence of direct positions within the same coordinate reference system (CRS). if no srsName attribute is given, the CRS shall be specified as part of the larger context this geometry element is part of, typically a geometric object like a point, curve, etc. The optional attribute count specifies the number of direct positions in the list. If the attribute count is present then the attribute srsDimension shall be present, too. The number of entries in the list is equal to the product of the dimensionality of the coordinate reference system (i.e. it is a derived value of the coordinate reference system definition) and the number of direct positions. This element is part of GML, version 3.2 that is referenced by railML® version 3.2. Within railML®, the railML® version is significant for the handling of this element rather than the GML version. Please consider the licence terms of GML.

Attributes: count: specifies the number of direct positions in the list. If the attribute count is present then the attribute srsDimension shall be present, too. (optional; xs:unsignedLong), axisLabels: a list of labels of the axes of the grid [gml/3.2.1/grids.xsd] (optional; NCNameList), srsDimension: specifies the number of dimensions represented by the CRS and the positions in the GML Point [1] (optional; xs:positiveInteger), srsName: references the Coordinate Reference System (CRS) that applies to the coordinates of the GML Point [2]. (optional; xs:anyURI); the URN value for an anyURI that references one object in the European Petroleum Survey Group (EPSG) database shall have the form: urn:ogc:def:objectType:EPSG:version:code. For further information see “Definition identifier URNs in OGC namespace” Version 1.1.2 Open Geospatial Consortium Inc. 2007, uomLabels: Ordered list of unit of measure (uom) labels for all the axes of this CRS. The value of the string in the gml:catalogSymbol should be used for this uom labels, after spaces and forbiddden characters are removed. When the axisLabels attribute is included, this attribute shall also be included. When the axisLabels attribute is omitted, this attribute shall also be omitted [gml/3.1.1/base/geometryBasic0d1d.xsd]. (optional; NCNameList)
*Notice: Elements may have different parent elements. As a consequence they may be used in different contexts. Please, consider this as well as a user of this Wiki as when developing this documentation further. Aspects that are only relevant with respect to one of several parents should be explained exclusively in the documentation of the respective parent element.
