Autoexport from the XML-Schema for element IS:lineString of railML ® version 3.3 |
| Documentation
|
A LineString is a special curve that consists of a single segment with linear interpolation. It is defined by two or more coordinate tuples, with linear interpolation between them. The number of direct positions in the list shall be at least two.

Attributes:
- 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),
- id: The attribute gml:id supports provision of a handle for the XML element representing a GML Object. Its use is mandatory for all GML objects. It is of XML type ID, so is constrained to be unique in the XML document within which it occurs [gmlBase.xsd]. (optional;
xs:ID); compare: Dev:Identities
|
*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.
