Pansharpen

Summary

Creates a higher-resolution multiband image by fusing a lower-resolution multispectral image and a higher-resolution panchromatic image.

Discussion

For more information about how this function works, see the Pansharpen raster function.

The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.

Syntax

Pansharpen (pan_raster, ms_raster, {ir_raster}, {fourth_band_of_ms_is_ir}, {weights}, {type}, {sensor})

Parameter	Explanation	Data Type
pan_raster	The input panchromatic raster.	Raster
ms_raster	The input multispectral raster.	Raster
ir_raster	Specify the path to a single-band image containing the near-infrared band. (The default value is None)	Raster
fourth_band_of_ms_is_ir	Specify that the fourth band of the input multispectral raster (ms_raster) is an infrared band. True—The fourth band of the input multispectral raster is an IR band. False—The multispectral raster contains an IR band. (The default value is True)	Boolean
weights	Specify weights applied to Red, Green, Blue, Near-Infrared bands. Sum of the weights is 1. For example, the weights for QuickBird imagery are [0.166, 0.167, 0.167, 0.5]. (The default value is [0.166, 0.167, 0.167, 0.5])	String
type [type,...]	Specify the Pansharpening method. IHS—Uses Intensity, Hue, and Saturation color space for data fusion. Brovey—Uses the Brovey algorithm based on spectral modeling for data fusion. ESRI—Uses the Esri algorithm based on spectral modeling for data fusion. This is the default. SimpleMean—Uses the averaged value between the red, green, and blue values and the panchromatic pixel value. Gram-Schmidt—Uses the Gram-Schmidt spectral-sharpening algorithm to sharpen multispectral data. (The default value is ESRI)	String
sensor [sensor,...]	Specify the sensor name of the input imagery when the pansharpening method is Gram-Schmidt. Supported raster data types include DubaiSat-2, GeoEye-1, GF-1 PMS, GF-2 PMS, IKONOS, Jilin-1, KOMPSAT-2, KOMPSAT-3, Landsat 1-5 MSS, Landsat 7 ETM+, Landsat 8, Pleiades-1, QuickBird, SkySat, SPOT 5, SPOT 6 SPOT 7, TH-01, UltraCam, WorldView-2, WorldView-3, WorldView-4, ZY1-02C PMS, ZY3-CRESDA, ZY3-SASMAC, and UNKNOWN. (The default value is None)	String

Return Value

Data Type	Explanation
Raster	The output pansharpened raster.
