SurfacePointCalculation

trait SurfacePointCalculation[T] extends FocalCalculation[T]

Calculation used for surface point calculations such as Slope, Aspect, and Hillshade

Uses a specific traversal strategy for performance benefits.

Note

For edge cells, the neighborhood points that lie outside the extent of the raster will be counted as having the same value as the focal point.

  1. abstract def result: T

    Definition Classes
    Resulting
  2. abstract def setValue(x: Int, y: Int, s: SurfacePoint): Unit

    Sets a result at (x,y) from a SurfacePoint

    Sets a result at (x,y) from a SurfacePoint

    Implementors need to provide this function to store the results of the surface point calculation.

  15. def execute(raster: Raster, n: Neighborhood, neighbors: Seq[Option[Raster]]): Unit

    Executes a specific traversal strategy for SurfacePointCalculation.

    Executes a specific traversal strategy for SurfacePointCalculation. The difference between this and ScanLine for CellwiseCalculation is that for edge cases, the value at the focus is added in place of out-of-border neighborhood values.

    raster

    Raster to execute against.

    n

    Neighborhood used (must be Square with dimension 1)

    neighbors

    Neighboring tiles

    Note

    All values in the neighborhood that are outside the raster grid are counted as having the focal value. Note that in the case the cell is outside the analysis area, but still inside the raster, the raster value will still be used.

    Assumes a Square(1) neighborhood.
