Constructor Detail

SpatialSimpleFeatureBinningStrategy

public SpatialSimpleFeatureBinningStrategy()

Create a binning strategy using a small number of bins. Usage of this method is not recommended, if you are to use this, it should be through serialization.

SpatialSimpleFeatureBinningStrategy

public SpatialSimpleFeatureBinningStrategy(SpatialBinningType type,
                                           int precision,
                                           boolean useCentroidOnly)

Parameters:

type - S2, H3, or GeoHash

precision - the resolution/length of the hash

useCentroidOnly - desired behavior for complex geometry such as lines and polygons whether to just aggregate one hash value based on the centroid or to apply the aggregation to all overlapping centroids

Method Detail

getGeometry

public org.locationtech.jts.geom.Geometry getGeometry(DataTypeAdapter<org.opengis.feature.simple.SimpleFeature> adapter,
                                                      org.opengis.feature.simple.SimpleFeature entry)

Description copied from class: SpatialBinningStrategy

Extract the geometry from the entry.

entry - The entry that will be binned using this strategy.

Returns:

The geometry object in the entry, or null if no geometry is found.
