The goal is to enable a geoserver WFS request with a 3D bounding box so that we receive only geometries not disjoint with that 3D bounding box.
In other words, there is a min and max for the third coordinate as well as the first two.
In 2D we have in KVP:
However, in 3D we get:
Only 3d geometries that qualify for the min and max pairs for all three axes are returned.
In order to accomplish this, Geotools must support
- 3D Envelopes: a 3D envelope geometry class and a 3D referenced envelope geometry class.
- 3D Bounding Boxes: a 3D Bounding Box has two additional attributes (min z and max z) and filters geometries using all three dimensions.

This section is used to make sure your proposal is complete (did you remember documentation?) and has enough paid or volunteer time lined up to be a success
- NC: Update API
- NC: Make new implementations
- NC: Review Documentation
The changes are API additions, rather than changes.
There will be the following new interfaces in geoapi:
- BBOX3D, for the 3D bbox filter, subinterface of BBOX
There will be the following new classes in main
- BBOX3DImpl, implementation of interface
- Envelope3D, Extension of JTS Envelope
- ReferencedEnvelope3D, Referenced version of Envelope3D
Furthermore, the FIlterFactory interfaces will be extended with the following methods:
- BBOX3D bbox(String propertyName, ReferencedEnvelope3D bbox);
- BBOX3D bbox( Expression geometry, ReferencedEnvelope3D bbox);
- BBOX3D bbox( Expression geometry, ReferencedEnvelope3D bbox, MatchAction matchAction);
