UTDF To GMNS Format
Convert UTDF files to GMNS format. This script converts UTDF files to GMNS format. It reads the UTDF file, extracts the relevant data, and writes it to GMNS format files. The resulting GMNS files are saved in the same directory as the input UTDF file.

GMNS Link Generation
There are two ways to generate GMNS links from UTDF files:
Create Link Line
This method creates a link line from the UTDF file. It uses the coordinates of the nodes in the UTDF file to create a line that represents the link.
The resulting link line is saved in the GMNS format.
Create Link Polygon
This method creates a link polygon from the UTDF file. It uses the coordinates of the nodes and number of lanes in each link to create a polygon that represents the link (With multiple lanes for each direction).

The resulting GMNS network can be opened in QGIS, ArcGIS or any other GIS software that supports GMNS format (Below: example nodes and links).
