All Implemented Interfaces:

GPTool

public class WeightedOverlay
extends AbstractGPTool

Overlays several rasters using a common measurement scale and weights each according to its importance. The Weighted Overlay tool is contained in the Spatial Analyst Tools tool box.

Software restrictions: none

Illustration:

Usage tips:

• All input rasters must be integer. A floating-point raster must first be converted to an integer raster before it can be used in Weighted Overlay. The Reclassification tools provide an effective way to do the conversion.
• Each value class in an input raster is assigned a new value based on an evaluation scale. These new values are reclassifications of the original input raster values. A restricted value is used for areas you want to exclude from the analysis.
• Each input raster is weighted according to its importance or its percent influence. The weight is a relative percentage, and the sum of the percent influence weights must equal 100 percent.
• Changing the remap_assignment evaluation scale value or the percentage influences can change the results of the weighted overlay analysis.
• The following environment settings affect this tool:
