WebFunctions can be applied to one or multiple layers. Thus, spatial functions split into four groups: local, focal, zonal and global ones [5], illustrated in Figure 1. { Local functions operate on every single cell in a layer. And the cell is pro-cessed without reference to surrounding cells. An example is a map trans-
WebFocal: Apply a function to a set of neighborhood values to calculate the output for a single cell, e.g. using a moving window, such as kernel. Zonal: Apply a function to a group of cells within a specified zone (zone can be provided as a raster or vector format). WebZonal functions create outputs in which the value of output cells are determined in part by the spatial association between cells in the input grids. In the "zonalmean" command example above, the zone grid is timber stands. Every cell …
