GeoPackage vector

This driver implements support for access to spatial tables in the OGC GeoPackage format standard (targeting 1.0/1.0.1) The GeoPackage standard uses a SQLite database file as a generic container, and the standard defines:

This driver reads and writes SQLite files from the file system, so it must be run by a user with read/write access to the files it is working with.

Starting with GDAL 2.0, the driver also supports reading and writing the following non-linear geometry types :CIRCULARSTRING, COMPOUNDCURVE, CURVEPOLYGON, MULTICURVE and MULTISURFACE

Starting with GDAL 2.0, GeoPackage raster/tiles are supported. See GeoPackage raster documentation page



The driver supports OGR attribute filters, and users are expected to provide filters in the SQLite dialect, as they will be executed directly against the database.

Starting with GDAL 2.0, SQL SELECT statements passed to ExecuteSQL() are also executed directly against the database. If Spatialite is used, a recent version (4.2.0) is needed and use of explicit cast operators AsGPB() is required to transform GeoPackage geometries to Spatialite geometries (the reverse conversion from Spatialite geometries is automatically done by the GPKG driver). It is also possible to use with any Spatialite version, but in a slower way, by specifying the "INDIRECT_SQLITE" dialect. In which case, GeoPackage geometries automatically appear as Spatialite geometries after translation by OGR.

Starting with GDAL 2.2, the "DROP TABLE layer_name" and "ALTER TABLE layer_name RENAME TO new_layer" statements can be used. They will update GeoPackage system tables.

When dropping a table, or removing records from tables, the space they occupied is not immediately released and kept in the pool of file pages that SQLite may reuse later. If you need to shrink the file to its minimum size, you need to issue an explicit "VACUUM" SQL request. Note that this will result in a full rewrite of the file.

SQL functions

Starting with GDAL 2.0, the following SQL functions, from the GeoPackage specification, are available : The following functions, with identical syntax and semantics as in Spatialite, are also available :

Link with Spatialite

Starting with GDAL 2.0, if it has been compiled against Spatialite 4.2 or later, it is also possible to use Spatialite SQL functions. Explicit transformation from GPKG geometry binary encoding to Spatialite geometry binary encoding must be done.

ogrinfo poly.gpkg -sql "SELECT ST_Buffer(CastAutomagic(geom),5) FROM poly"

Starting with Spatialite 4.3, CastAutomagic is no longer needed.

Transaction support (GDAL >= 2.0)

The driver implements transactions at the database level, per RFC 54

Opening options

The following open options are available: Note: open options are typically specified with "-oo name=value" syntax in most OGR utilities, or with the GDALOpenEx() API call.

Creation Issues

When creating a new GeoPackage file, the driver will attempt to force the database into a UTF-8 mode for text handling, satisfying the OGR strict UTF-8 capability. For pre-existing files, the driver will work with whatever it's given.

Dataset Creation Options

None related to vector

Layer Creation Options


(GDAL >=2.0) GDAL uses the standardized gpkg_metadata and gpkg_metadata_reference tables to read and write metadata, on the dataset and layer objects.

GDAL metadata, from the default metadata domain and possibly other metadata domains, is serialized in a single XML document, conformant with the format used in GDAL PAM (Persistent Auxiliary Metadata) .aux.xml files, and registered with md_scope=dataset and md_standard_uri= in gpkg_metadata. For the dataset, this entry is referenced in gpkg_metadata_reference with a reference_scope=geopackage. For a layer, this entry is referenced in gpkg_metadata_reference with a reference_scope=table and table_name={name of the table}

Metadata not originating from GDAL can be read by the driver and will be exposed as metadata items with keys of the form GPKG_METADATA_ITEM_XXX and values the content of the metadata columns of the gpkg_metadata table. Update of such metadata is not currently supported through GDAL interfaces ( although it can be through direct SQL commands).

The specific DESCRIPTION and IDENTIFIER metadata item of the default metadata domain can be used in read/write to read from/update the corresponding columns of the gpkg_contents table.
