Constructor Details

NearestNeighbourCoverage

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
