Multilevel Linear Referencing System (MLRS)


Multilevel Linear Referencing System

Intergraph’s Multilevel Linear Referencing System (MLRS) application provides everything you need to build, maintain, and analyze a multilevel, temporal linear referencing system for representing road networks. Editing tools give you a complete data maintenance environment for MLRS data. You can easily add a temporal dimension to both your data maintenance and data analysis.

MLRS is an automated approach to managing the components of a linear reference system network and event data, regardless of the location method or geometric representation used. MLRS is different from the traditional LRS management practice in that the base network can represent multiple linear referencing methods (LRMs), such as county-route-logmile, street name-address, intersection-offset, etc., and can be displayed on the map using multiple geometric representations. Intergraph’s core data model and software manage the various parts of the LRS independently through database joins and relationships. A temporally stable datum links these component parts to support event location stability and temporal data management and analysis. Our MLRS application is also the foundation for our other transportation solutions.
