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.
(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.
(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 |
Data Type | Explanation |
Raster | The output pansharpened raster. |
