Compute Pansharpen Weights (Data Management)
Summary
Calculates an optimal set of pan-sharpened weights for new or custom sensor data.
Usage
-
This tool will calculate an optimal set of pan-sharpened weights, which can be used in other tools that require pan-sharpened weights.
If a raster product is used as the Input Raster, the band order within the raster product template will be honored.
Syntax
Parameter | Explanation | Data Type |
in_raster |
The input multispectral raster. | Mosaic Dataset; Mosaic Layer; Raster Dataset; Raster Layer |
in_panchromatic_image |
The input panchromatic raster. | Raster Layer |
band_indexes (Optional) | The band order for the pansharpened weights. If a raster product is used as the in_raster parameter, the band order within the raster product template will be used. | String |
Code Sample
This is a Python sample for the ComputePansharpenWeights tool.
import arcpy
arcpy.ComputePansharpenWeights_management(
"c:/data/rgb.tif", "c:/data/image.tif", "3 2 1 4")
This is a Python script sample for the ComputePansharpenWeights tool.
#Run Compute Pan Sharpen Weights tool using the bands 4,3,2,1
import arcpy
InMSraster = "C:\\Landsat7\\L71046029_02920050705_MTL.txt\Multispectral"
InPANraster = "C:\\Landsat7\\L71046029_02920050705_MTL.txt\Panchromatic"
band_index = "3 2 1 5"
arcpy.ComputePansharpenWeights_management(InMSraster, InPANraster, band_index)
This is a Python script sample to use the ComputePansharpenWeights output in another tool.
#Compute the pansharpening weights and use the results in the
#create pansharpening tool.
try:
import arcpy
InRGBraster = "C:\\temp\\rgb.img"
InPanraster = "C:\\temp\\pan.tif"
#Compute Pan Sharpen Weights
out_pan_weight = arcpy.ComputePansharpenWeights_management(
InRGBraster, InPanraster, "3 2 1 4")
#Get results
pansharpen_weights = out_pan_weight.getOutput(0)
#Split the results string for weights of each band
pansplit = pansharpen_weights.split(";")
#Run the Create pan sharpened raster dataset tool.
