Pansharpen

サマリー

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

説明

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.

構文

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

パラメーター	説明	データ タイプ
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. (デフォルト値は次のとおりです 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. (デフォルト値は次のとおりです 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]. (デフォルト値は次のとおりです [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. (デフォルト値は次のとおりです 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. (デフォルト値は次のとおりです None)	String

戻り値

データ タイプ	説明
