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.
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.
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.
Calculation used for surface point calculations such as Slope, Aspect, and Hillshade
Uses a specific traversal strategy for performance benefits.
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.
