Introduction

Documentation

Syntax

Autoexport from the XML-Schema for element GML4RAILML:pos of railML® version 3.2
 
Documentation Direct position instances hold the coordinates for a position within some coordinate reference system (CRS). Since direct positions, as data types, will often be included in larger objects (such as geometry elements) that have references to CRS, the srsName attribute will in general be missing, if this particular direct position is included in a larger element with such a reference to a CRS. In this case, the CRS is implicitly assumed to take on the value of the containing object's 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.
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.

Children None
Attributes:
  • srsDimension: Schema documentation missing! (optional; xs:positiveInteger),

  • srsName: Schema documentation missing! (optional; xs:anyURI)
*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.
