TopoJSON to GeoPackage Converter
Import compressed TopoJSON layers into indexable databases.
Extract lightweight topologies and organize them into structured databases. This converter will expand shared line systems into individual database records within a GeoPackage, complete with spatial indexes.
Direct Target Stream Unavailable
This direct channel is planned for an upcoming release. In the meantime, consult the technical specifications and guidelines below.
Specification Rules
- Import space-saving web topologies back into active GIS projects
- Save compressed map datasets in indexable local databases
- Run offline spatial queries on TopoJSON boundaries
- Decompressing shared boundaries increases overall database size
- Requires custom format drivers to parse topology structures
- Conversion processes are more CPU-intensive for large layers
GDAL Direct Equivalent Terminal Command
sh console shell
$ogr2ogr -f GPKG output.gpkg input.topojson
Frequently Asked Queries
What happens during decompression?
Compressed boundary tracks expand into individual vector boundaries within the SQLite database.
Is spatial search performance optimized?
Yes. The generated files are structured with spatial index columns inside the database tables.
Are multiple layers supported?
Yes, different topologies convert into separate, organized tables within the database.
