LinearReferencing

Linear referencing is the method of storing geographic locations by using relative positions along a measured linear feature.

Classes

Name Description  
DistanceExpression Core structure carrying linearly-referenced information.  
ILinearElementProvidedBySource Relationship associating Linear-Elements with the elements they came from.  
ILinearLocationLocatesElement Relationship indicating bis:Element being linearly-located by a concrete instance mixing-in ILinearLocationElement.  
ILinearlyLocatedAlongILinearElement Relationship indicating the Linear-Element along which concrete instances mixing-in ILinearlyLocated are located.  
ILinearlyLocatedAttributesElement Relationship indicating the bis:Element being attributed by a concrete instance mixing-in ILinearlyLocatedAttribution.  
IReferentReferencesElement Relationship indicating the bis:SpatialElement being used as Referent for Linear Referencing purposes.  
LinearElement A class offering services for linearly-located data along a Linear-Element.  
LinearLocation Linear Referencing Location attached to an Element not inherently Linearly Referenced.  
LinearLocationElement Base class for Spatial Location Element implementations that are linearly located along a Linear-Element.  
LinearlyLocated A class offering services for LinearlyLocated elements.  
LinearlyLocatedAttribution Base class for Spatial Location Element subclasses representing properties whose value is located along a Linear-Element and only applies to a portion of an Element.  
LinearlyReferencedAtLocation Concrete multi-aspect class carrying 'at' linearly-referenced positions along a Linear-Element.  
LinearlyReferencedAtPositionRefersToReferent Relationship indicating the referent used by a particular linearly-referenced At position.  
LinearlyReferencedFromPositionRefersToReferent Relationship indicating the referent used by a particular linearly-referenced From position.  
LinearlyReferencedFromToLocation Concrete multi-aspect class carrying 'from-to' linearly-referenced positions along a Linear-Element.  
LinearlyReferencedLocation Base class for multi-aspects carrying linearly-referenced locations.  
LinearlyReferencedToPositionRefersToReferent Relationship indicating the referent used by a particular linearly-referenced To position.  
LinearPhysicalElement Base class for Physical Elements that are inherently linearly located along a Linear-Element.  
LinearReferencingSchema Schema for the LinearReferencing domain.  
Referent Referent-implementation turning any bis:SpatialElement not inherently Linearly-Referenced into a Referent for Linear-Referencing purposes.  
ReferentElement Spatial Location Element that can play the role of a Referent (known location along a Linear-Element).  

Interfaces

Name Description

LinearlyLocatedMultipleAt Interface to optionally be implemented by Elements inherently Linearly-Located whose linear-locations are always at-positions.  
LinearlyLocatedMultipleFromTo Interface to optionally be implemented by Elements inherently Linearly-Located whose linear-locations are always from-to-positions.  
LinearlyLocatedSingleAt Interface to optionally be implemented by Elements inherently Linearly-Located whose linear-locations are always a single at-position.  
LinearlyLocatedSingleFromTo Interface to optionally be implemented by Elements inherently Linearly-Located whose linear-locations are always a single from-to-position.
