XRoad VGP road alignment format

XRoad VGP horizontal and vertical alignment. If one file has multiple horizontal and/or vertical geometries, it is divided automatically into different files.

If the file contains only one road line, the file name is used directly. If there are multiple lines, each file is named by combination of values defined in lines TIE, TIEVE and LINJA. For example, file containing values TIE=mt147, TIEVE=ve1 and LINJA=or is named to mt147_ve1_or.vgp. Special setting RoadFlag can be used to force same naming rule for files containing only one road line.

Found single line id values are read to the attributes GROUP, NAME and VERSION. Writing writes them back to the file.

Road line code is read from the LINJA line. This code determines the line drawing using the code file and it is enabled by removing the default code 9100 from the converter settings.
