Moving average (Point interpolation)
The moving average operation is a point interpolation which requires a point map as input and returns a raster map as output. To the output pixels, weighted averaged point values are assigned. The weight factors for the points are calculated by a user-specified weight function. The weight function ensures that points close to an output pixel obtain larger weights than points which are farther away. Furthermore, the weight functions are implemented in such a way that points which are farther away from an output pixel than a user-defined limiting distance obtain weight zero.
When interpolating point values, it is for time efficiency reasons strongly advised to choose a rather large pixel size for the output map. Further interpolation on the raster map values can be performed using the Densify operation or the Resample operation.
