VDV - VDV-451/VDV-452/INTREST Data Format¶
New in version 2.1.
Driver short name
Driver built-in by default
This driver is built-in by default
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” :
(read/write) VDV-452 standard for route network / timetable
(read/only) “INTREST Data format” used by the Austrian official open government street graph
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.
This driver supports the
This driver supports georeferencing
This driver supports virtual I/O operations (/vsimem/, etc.)
The driver can create new layers (either in the same file, or in separate files in the same directory). 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.
The following dataset creation options are available:
SINGLE_FILE=YES/NO. Whether several layers should be put in the same file. If NO, the name is assumed to be a directory name. Defaults to YES.
The following layer creation options are available:
EXTENSION=string. Extension used when creation files in separate layers, i.e. only for SINGLE_FILE=NO dataset creation option. Defaults to x10.
PROFILE=GENERIC/VDV-452/VDV-452-ENGLISH/VDV-452-GERMAN. Defaults to GENERIC. Describe which profile the writer should conform to. VDV-452 will restrict layer and field names to be the one allowed by the VDV-452 standard (either in English or German). VDV-452-ENGLISH and VDV-452-GERMAN will restrict the VDV-452 to the specified language. The configuration file describing VDV-452 table and field names is vdv452.xml located in the GDAL_DATA directory.
PROFILE_STRICT=YES/NO. Whether checks of profile should be strict. In strict mode, unexpected layer or field names will be rejected. Defaults to NO.
CREATE_ALL_FIELDS=YES/NO. Whether all fields of predefined profiles should be created at layer creation. Defaults to YES.
STANDARD_HEADER=YES/NO. Whether to write standard header fields (i.e mod, src, chs, ver, ifv, dve, fft). If set to NO, only explicitly specified HEADER_xxx fields will be written. Defaults to YES.
HEADER_SRC=string: Value of the src header field. Defaults to UNKNOWN.
HEADER_SRC_DATE=string: Value of the date of the src header field as DD.MM.YYYY. Defaults to current date (in GMT).
HEADER_SRC_TIME=string: Value of the time of the src header field as HH.MM.SS. Defaults to current time (in GMT)
HEADER_CHS=string: Value of the chs header field. Defaults to ISO8859-1.
HEADER_VER=string: Value of the ver header field. Defaults to 1.4.
HEADER_IFV=string: Value of the ifv header field. Defaults to 1.4.
HEADER_DVE=string: Value of the dve header field. Defaults to 1.4.
HEADER_FFT=string: Value of the fft header field. Defaults to ‘’ (empty string).
HEADER_xxx=string: Value of the xxx (user defined) header field.
