Vertices.csv

The first of the road network input files is vertices.csv which contains 3 fields: NODE,X,Y. The first field is a vertex ID label followed by the X and Y coordinates of the vertex on the map in the map units (ID label is derived from the FNODE, TNODE labels in the final access road file). Vertices represent landings or access points on to the road network, and are always located as the end points of line segments.

The following example illustrates a number of vertices.csv records.
