Location referencing mechanisms

Represents an element in a linear reference system that can be used for linear references.

Reference to a point location. This may be the baseclass for many different types of location referencing mechanisms such as: - Linear referencing - AGORA-C referencing - Alert-C referencing The subject is further specified in standards and specifications such as: - ISO 19133 - ISO 17572 (parts 1, 2 and 3) - EuroRoadS - eMotion The subject of linear referencing is also currently being standardised in ISO 19148.

Reference to a linear location which is the whole or part of an LRSElement or another linear part of the network. This may be the baseclass for many different types of location referencing mechanisms such as: - Linear referencing - AGORA-C referencing - Alert-C referencing The subject is further specified in standards and specifications such as: - ISO 19133 - ISO 17572 (parts 1, 2 and 3) - EuroRoadS - eMotion The subject of linear referencing is also currently being standardised in ISO 19148.

A reference to a node in a network

Represents a location relative to a network. The reference is the label which is assigned to a location. With a single LRM, one reference must define unambiguously and exactly one location in the location referencing system. The reference is the string of data which is passed between different implementations of a location referencing system to identify the location. [ISO 17572-1]

A reference to an area location related to a network. This may be the baseclass for many different types of location referencing mechanisms such as: - AGORA-C referencing - Alert-C referencing The subject is further specified in standards and specifications such as: - ISO 19133 - ISO 17572 (parts 1, 2 and 3) - EuroRoadS - eMotion

Reference to a linear location which is the whole or part of an LRSElement.
