GPTool

public class ExtractByCircle
extends AbstractGPTool

Extracts the cells of a raster based on a circle. The Extract by Circle tool is contained in the Spatial Analyst Tools tool box.

Usage tips:

• The center of the cell is used to determine whether a cell is inside or outside a circle. If the center is within the arc of the circle, the cell is considered fully inside even if portions of the cell fall outside the circle.
• Cell locations that are not selected are assigned a value of NoData.
• When a is specified as input, a new multiband raster will be created as output. Each individual band in the input multiband raster will be analyzed accordingly.The default output format is an . Note that the name of an ESRI grid stack cannot start with a number, use spaces, or be more than 9 characters in length.
• If the input is a layer created from a multiband raster with more than three bands, the extraction operation will only consider the bands that were loaded (symbolized) by the layer. As a result, the output multiband raster can only have three bands, corresponding to those used in the display of the input layer.
• If the input raster is integer, the output raster will be integer. If the input is floating point, the output will be floating point.

Constructor Detail

ExtractByCircle

public ExtractByCircle()

Creates the Extract by Circle tool with defaults.

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

ExtractByCircle

public ExtractByCircle(Object inRaster,
                       Object centerPoint,
                       double radius,
                       Object outRaster)

Creates the Extract by Circle 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 - the input raster from which cells will be extracted.

centerPoint - the Point class dictates the center coordinate (x,y) of the circle defining the area to be extracted. the form of the class is: the coordinates are specified in the same map units as the input raster.

• Point (x, y)

radius - radius of the circle defining the area to be extracted. the radius is specified in map units and is in the same units as the input raster.

outRaster - the output raster containing the cell values extracted from the input raster.
