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.
This driver supports the
This driver supports georeferencing
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.
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.
TEMPORARY_DIR=path: Path to an existing directory where temporary files should be created. Only used if SPATIAL_INDEX=YES. If not specified, the directory of the output file will be used for regular filenames. For other VSI file systems, the temporary directory will be the one decided by the
CPLGenerateTempFilename()function. “/vsimem/” can be used for in-memory temporary files.
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.fgbmust 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
