Abstract

A method for mapping a railroad track is provided. The method includes defining a plurality of track segments that form the railroad track and determining coordinates of each track segment. The method also includes storing the coordinates of each track segment in a database as map segments and linking the map segments stored in the database to create a multi-dimensional railroad track map.
