VDV - VDV-451/VDV-452/INTREST Data Format

(GDAL/OGR >= 2.1.0)

This driver can read and create text files following the VDV-451 file format, which is a text format similar to CSV files, potentially containing several layers within the same file.

It supports in particular reading 2 "profiles" :

The generic reader/writer for VDV-451/VDV-452 can support arbitrarily large files. For the INTREST data case, for combined layers in a single file, the driver ingests the whole file in memory to reconstruct the Link layer.

Interleave reading among layers is supported in files with multiple layers.

It can append a new layer into an existing file, but it cannot append/edit/delete features to an existing layer, or modify the attribute structure of an existing layer after features have been written.
