Vector Tiles ============ .. only:: html .. contents:: :local: :depth: 1 .. _qgiswritevectortiles_mbtiles: Write vector tiles (MBTiles) ---------------------------- Exports one or more vector layers to vector tiles, a data format optimized for fast map rendering and small data size. MBTiles is a specification for storing tiled map data in SQLite databases for immediate usage and for transfer. MBTiles files are known as tilesets. Parameters .......... .. list-table:: :header-rows: 1 :widths: 20 20 20 40 * - Label - Name - Type - Description * - **Input layers** - ``INPUT`` - [vector: any][list] - A list of layers to combine to generate the vector tiles * - **Minimum zoom level** - ``MIN_ZOOM`` - [number] Default: 0 - The lowest zoom level for which the tileset provides data. Set between 0 and 24. * - **Maximum zoom level** - ``MAX_ZOOM`` - [number] Default: 3 - The highest zoom level for which the tileset provides data. Set between 0 and 24. * - **Extent** Optional - ``EXTENT`` - [extent] Default: Not set - The maximum extent of the rendered map area. Bounds must define an area covered by all zoom levels. * - **Metadata: Name** Optional - ``META_NAME`` - [string] - Name of the tileset * - **Metadata: Description** Optional - ``META_DESCRIPTION`` - [string] - A description of the tileset's contents * - **Metadata: Attribution** Optional - ``META_ATTRIBUTION`` - [string] - An attribution string, which explains the sources of data and/or style for the map. * - **Metadata: Version** Optional - ``META_VERSION`` - [string] - The version of the tileset. This refers to a revision of the tileset itself, not of the MBTiles specification. * - **Metadata: Type** Optional - ``META_TYPE`` - [string] - Type of tileset. Possible values are ``overlay`` or ``baselayer``. * - **Metadata: Center** Optional - ``META_CENTER`` - [string] - The center (string of comma-separated numbers: the longitude, latitude, and zoom level) of the default view of the map. Example: ``-122.1906,37.7599,11`` * - **Destination MBTiles** - ``OUTPUT`` - [vector tiles] Default: [Save to temporary file] - Specification of the output MBTiles file.

Set between 0 and 24. * - **Extent** Optional - ``EXTENT`` - [extent] Default: Not set - The maximum extent of the rendered map area. Bounds must define an area covered by all zoom levels. * - **Output directory** - ``OUTPUT_DIRECTORY`` - [folder] Default: [Save to temporary folder] - Specification of the output vector tiles folder.
