      public NearestNeighbourCoverage(Supplier<NearestNeighbourIndex> indexSupplier, nz.org.riskscape.engine.types.Type type, org.geotools.api.referencing.crs.CoordinateReferenceSystem coordinateReferenceSystem, nz.org.riskscape.engine.SRIDSet sridSet)
      Parameters:
      indexSupplier - to obtain the nearest neighbour index when it is first required.
      type - the struct type of the tuples that the index will return.
      coordinateReferenceSystem - the crs of the indexed geometry. Points will be reprojected to this crs before being used to query the index
      sridSet - to use for reprojecting geometries
