Mapbox Vector Tiles Extension

Extension Title

Mapbox Vector Tiles


The GeoPackage Mapbox Vector Tiles extension defines the rules and requirements for encoding vector tiles in a GeoPackage data store as Mapbox Vector Tiles. This extension is based on the Mapbox Vector Tiles (MVT) specification version 2.1. Note that this format uses Google Protocol Buffers as the content encoding for each tile.

This extension, like all GeoPackage extensions, is intended to be transparent and to not interfere with GeoPackage-compliant, but non-supporting, software packages.

Extension Author

Image Matters LLC, in collaboration with the participants of the OGC Vector Tiles Pilot.

Extension Name or Template

im_vector_tiles_mapbox (If this extension is adopted by OGC, then gpkg_mapbox_vector_tiles will be named as an alias.)

Extension Type

This extension defines an encoding for the Vector Tiles Extension.


This extension defines a specific encoding for Vector Tiles in a GeoPackage.




If this extension is in use, then all of the Vector Tiles Extension applies.

User Data Tables

Like other tile-based content, the physical data is stored in user-defined tiles tables. The tile_data is a Google Protocol Buffer as defined by MVT.


To use this extension, add a row to this table for each tile pyramid user data table.

The values in the definition column SHOULD refer in some human-readable way to this extension specification. If the extension is adopted by OGC, it will gain the "gpkg_" prefix and get a different definition permalink.

You can’t perform that action at this time.
