New in version 3.1.

Driver short name


Driver built-in by default

This driver is built-in by default

This driver implements read/write support for access to features encoded in FlatGeobuf format, a performant binary encoding for geographic data based on flatbuffers that can hold a collection of Simple Features.

Driver capabilities

Supports Create()

This driver supports the GDALDriver::Create() operation

Supports Georeferencing

This driver supports georeferencing

Supports VirtualIO

This driver supports virtual I/O operations (/vsimem/, etc.)

Multi layer support

A single .fgb file only contains one single layer. For multiple layer support, it is possible to put several .fgb files in a directory, and use that directory name as the connection string.

On creation, passing a filename without a .fgb suffix will instruct the driver to create a directory of that name, and create layers as .fgb files in that directory.

Open options

  • VERIFY_BUFFERS=YES/NO: Set to YES to verify buffers when reading. This can provide some protection for invalid/corrupt data with a performance trade off. Defaults to YES.

Dataset Creation Options


Layer Creation Options

  • SPATIAL_INDEX=YES/NO: Set to YES to create a spatial index. Defaults to YES.


  • Simple translation of a single shapefile into a FlatGeobuf file. The file ‘filename.fgb’ will be created with the features from abc.shp and attributes from abc.dbf. The file filename.fgb must not already exist, as it will be created.

    % ogr2ogr -f FlatGeobuf filename.fgb abc.shp
  • Conversion of a Geopackage file with multiple layers:

    % ogr2ogr -f FlatGeobuf my_fgb_dataset input.gpkg
