PostGIS Tiles

implmature

Optimized vector tile generation using ST_AsMVT from PostGIS.

Scope

It is highly recommended to enable this extension for simple mappings (see limitations). That will speed up vector tile generation roughly by a factor of 4.

Limitations

Only simple value properties are supported. That means no objects, arrays, transformations or joins. Such properties may be excluded from the generated tiles, see option unsupportedProperties. The native CRS must not have a forced axis order.

Configuration

Options

Name	Default	Description	Type	Since
