SIGMA

Extensive graphic overview of tracks and their surroundings
SIGMA combines information about a railroad track’s design and dimensions and develops a generic data model that represents the track as well as different objects around the track, such as signs or platforms. Track switches are also depicted. The geographic and schematic representation generated by SIGMA can be used to develop an even more extensive graphic overview of the track using ArcGIS Schematics.

Multiple scenario views
SIGMA uses track data to develop multiple scenarios. Users can view scenarios for the entire track or a subset of the track. The system reconstructs the track’s surface and surroundings to sub-centimeter precision, including location, cant, slope, height, curvature, design-speed and other dimensions.

CAD/GIS integration through FME server
A key feature of SIGMA is its ability to import and export data in various formats with a feature manipulation engine (FME). The FME is used to export track information to .dgn files for use in a Bentley MicroStation or with 3D models.
