- It checks root, feature, and geometry-level boxes, including 2D/3D positions and already-cut antimeridian geometries.
Field notes
The checker compares declared bounds with tight extents calculated from coordinates, including nested boxes on features and geometries. It handles 2D and 3D positions and already-cut geometry across the antimeridian. Its scope is deliberately limited: it does not repair coordinates, projections, polygon topology, or invalid shapes, and it warns that rewriting JSON can round unusually precise numeric literals.
