KernelDensity

case class KernelDensity (outputRasterExtent: Op[RasterExtent], kernel: Op[Kernel], points: Op[Array[Point]]) extends Op3[RasterExtent, Kernel, Array[Point], IntRaster] with Product with Serializable

Compute the kernel density of a set of points onto a raster

This operation is currently O(n*m) where n is the number of points and m is the size of the kernel array.

See also

geotrellis.operation.Kernel$ for methods of creating the input kernel
