Abstract
A method and system are provided for determining the geographic locations of events in a linear referencing system (LRS), such as a LRS for the Department of Transportation. The method and system utilize similarities between a LRS and the postal addressing system used in the United States. A LRS event geocoding database and schema are created from portions of the postal addressing system schema and geographic information system (GIS) schema. LRS data is encoded as postal address data as defined in the postal addressing system. The LRS data and GIS data are conflated to populate the LRS event geocoding database using similar transformation logic as for current postal address geocoding. The geographic location of a given LRS event is generated using geocoding software that utilizes the linear measure implicit in the LRS event identifier and the LRS event geocoding database.
