    Compute an Inverse Distance Weighting raster over the given extent from the given set known-points.

    Compute an Inverse Distance Weighting raster over the given extent from the given set known-points. Please see https://en.wikipedia.org/wiki/Inverse_distance_weighting for more details.

    points

    A collection of known-points

    re

    The study area

    returns

    The data interpolated across the study area

  18. def kernelDensity[D](points: Seq[PointFeature[D]], transform: (D) ⇒ Int, kernel: Kernel, rasterExtent: RasterExtent): Tile

    Computes a Density raster based on the Kernel and set of points provided.

    Computes a Density raster based on the Kernel and set of points provided.

    points

    Sequence of point features who's values will be used to compute the density.

    transform

    Function that transforms the point feature's data into an Int value.

    kernel

    Kernel to be used in the computation.

    rasterExtent

    Raster extent of the resulting raster.

    Note

    KernelDensity does not currently support Double raster data. If you use a Raster with a Double CellType (FloatConstantNoDataCellType, DoubleConstantNoDataCellType) the data values will be rounded to integers.
