MBTiles Output Format

MBTiles WMS Output Format

Any WMS GetMap request can be returned in the form of a Geopackage by specifying format=mbtiles as output format (see WMS output formats). The returned result will be an MBTiles file with a single tile layer.

The following additional parameters can be passed on using format_options:

  • tileset_name: name to be used for tileset in mbtiles file (default is name of layer(s)).

  • min_zoom, max_zoom, min_column, max_column, min_row, max_row: set the minimum and maximum zoom level, column, and rows

  • gridset: name of gridset to use (otherwise default for CRS is used)

Warning

The GetMap request won’t be subject to any execution time limit, a client can thus make request that will takes very long times to execute by providing a high max_zoom value.

MBTiles WPS Process

It is possible to generate an mbtiles file by calling the WPS process gs:MBTiles. This process requires the following parameters:

  • layername: Name of the input layer.

  • format : format of the final images composing the file.

  • minZoom, maxZoom, minColumn, maxColumn, minRow, maxRow: (Optional) set the minimum and maximum zoom level, column, and rows.

  • boundingbox: (Optional) Bounding box of the final mbtiles. If CRS is not set, the layer native one is used.

  • filename: (Optional) name of the mbtiles file created.

  • bgColor: (Optional) value associated to the background colour.

  • transparency: (Optional) parameter indicating if the transparency must be present.

  • stylename, stylepath, stylebody: (Optional) style to associate to the layer. Only one of these 3 parameters can be used.

The process returns an URL containing the path of the generated file.

Warning

The process implementation does not currently support cancellation, a client can thus make request that will takes very long times to execute by providing a high max_zoom value.
