Description

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:
BBOX=x0,y0,x1,y1

However, in 3D we get:
BBOX=x0,y0,z0,x1,y1,z1

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.

  1. NC: Update API
  2. NC: Make new implementations
  3. NC: Review Documentation

API Changes

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
  • ReferencedEnvelope3D, Extension of ReferencedEnvelope3D, extends JTS Envelope methods to use 3D coordinates and provides referenced envelope support for 3D coordinates

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);
