GPTool

public class Warp
extends AbstractGPTool

Performs a transformation on the raster based on the source and target control points using a polynomial transformation. This is similar to georeferencing using a text file. The Warp tool is contained in the Data Management Tools tool box.

Usage tips:

• You must specify the source and target coordinates. The transformation type (polynomial order) from which to choose is dependent on the number of control points entered.
• The default polynomial order (1) will perform an affine transformation.
• Warp is useful when the raster requires a systematic geometric correction that can be modeled with a polynomial. A spatial transformation can invert or remove a distortion by using polynomial transformation of the proper order. The higher the order, the more complex the distortion that can be corrected. The higher orders of polynomial will involve progressively more processing time.
• To determine the minimum number of links necessary for a given order of polynomial, use the following formula:
• You can save your output to BIL, BIP, BMP, BSQ, DAT, GIF, GRID, IMG, JPEG, JPEG 2000, PNG, TIFF, or any geodatabase raster dataset.
• When storing your raster dataset to a JPEG file, a JPEG 2000 file, or a geodatabase, you can specify a Compression type and Compression Quality within the Environment Settings.

Constructor Detail

Warp

public Warp()

Creates the Warp tool with defaults.

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

Warp

public Warp(java.lang.Object inRaster,
            java.lang.Object sourceControlPoints,
            java.lang.Object targetControlPoints,
            java.lang.Object outRaster)

Creates the Warp 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 dataset.

sourceControlPoints - the source points are the "from" coordinates of the links.

targetControlPoints - the target points are the "to" coordinates of the links.

outRaster - output raster dataset. when storing the raster dataset in a file format, you need to specify the file extension: when storing a raster dataset in a geodatabase, no file extension should be added to the name of the raster dataset. when storing your raster dataset to a JPEG file, a JPEG 2000 file, a TIFF file, or a geodatabase, you can specify a compression type and compression quality.
