Use Case ONTO11

Tessellate geometry

As a GeoSPARQL data user I would like to retrieve tessellation of a geometry with adaptive triangles.

Examples: Given a polygon, return triangulated irregular network.

Function signature:

tesselate(geometry: ogc:geomLiteral): ogc:geomLiteral

Actor: GeoSPARQL data user (human or software agent querying RDF dataset with GeoSPARQL)

Preconditions

Features and Geometries with 3D representations are present in a dataset to be queried. The tesselate function is discoverable

Postconditions

A SPARQL query can be executed that includes a function to produce a tessellated geometry from a given geometry.
The results of the query are known to be true or false in 3D or 2D.

Steps

Actor: discovers tessellate function implemented by the system
Actor: executes a SPARQL query containing tessellate function with a geometry argument.
System: returns a SPARQL result with a tessellated equivalent of a given geometry.

@ar-chad Is there a specific algorithm that should be used here?
