GPTool

public class Slope
extends AbstractGPTool

Identifies the rate of maximum change in z-value from each cell. The Slope tool is contained in the 3D Analyst Tools tool box.

Software restrictions: none

Illustration:

Usage tips:

• Slope is the rate of maximum change in z-value from each cell.
• The use of a z-factor is essential for correct slope calculations when the surface z units are expressed in units different from the ground x,y units.
• The range of slope values in degrees is 0 to 90. For percent rise, the range is 0 for near infinity. A flat surface is 0 percent, a 45 degree surface is 100 percent, and as the surface becomes more vertical, the percent rise becomes increasingly larger.
• If the center cell in the immediate neighborhood (3 x 3 window) is NoData, the output is NoData.
• If any neighborhood cells are NoData, they are assigned the value of the center cell; then the slope is computed.
• The following environment settings affect this tool:

Constructor Detail

Slope

public Slope()

Creates the Slope tool with defaults.

Initializes the array of tool parameters with the default values specified when the tool was created.

Slope

public Slope(Object inRaster,
             Object outRaster)

Creates the Slope tool with the required parameters.

Initializes the array of tool parameters with the values as specified for the required parameters and with the default values for the other parameters.

Parameters:

inRaster - Composite Geodataset, input raster.

outRaster - Raster Dataset, the raster to be created.

Method Detail

getInRaster

public Object getInRaster()

Returns the Input raster parameter of this tool . This parameter is Composite Geodataset, input raster. This is a required parameter.

Returns:

the Input raster

setInRaster

public void setInRaster(Object inRaster)

Sets the Input raster parameter of this tool . This parameter is Composite Geodataset, input raster. This is a required parameter.

Parameters:

inRaster - Composite Geodataset, input raster.

getOutRaster

public Object getOutRaster()

Returns the Output raster parameter of this tool . This parameter is Raster Dataset, the raster to be created. This is a required parameter.

Returns:

the Output raster

setOutRaster

public void setOutRaster(Object outRaster)

Sets the Output raster parameter of this tool . This parameter is Raster Dataset, the raster to be created. This is a required parameter.

Parameters:

outRaster - Raster Dataset, the raster to be created.

getOutputMeasurement

public String getOutputMeasurement()

Returns the Output measurement parameter of this tool . This parameter is String, determines the measurement units (degrees or percentages) of the output slope data. This is an optional parameter.

Returns:

the Output measurement

setOutputMeasurement

public void setOutputMeasurement(String outputMeasurement)

Sets the Output measurement parameter of this tool . This parameter is String, determines the measurement units (degrees or percentages) of the output slope data. This is an optional parameter.

Parameters:
