SpatialJSON WFS Output Format Extension

This module adds the SpatialJSON WFS output format. The SpatialJSON format is a more compact and memory-friendly variant of GeoServer's GeoJSON format. It aims to save space by applying several optimizations to traditional GeoJSON format for simple feature results. Most of these optimizations work by removing redundand information from the JSON-encoded features.

A service exception is thrown if the result contains complex features as the SpatialJSON format does not handle those.

Note

The SpatialJSON format is not compatible with GeoJSON. A SpatialJSON enabled reader is required to decode features transferred in SpatialJSON format.

This module adds two additional WFS output formats for requesting simple features in SpatialJSON format:

• application/json; subtype=json/spatial for requesting SpatialJSON
• text/javascript; subtype=json/spatial for requesting SpatialJSON as a JSONP request

Warning

At the time of writing, this format is still work in progress and changes may be applied in the future.
