How much i run code resample


I do not get output, someone could help.

image graph.xml (528 Bytes) processDataset.bat (1.9 KB) resample_20m.properties (47 Bytes)

D:\new>processDataset.bat graph.xml resample_20m.properties “D:\new\input_zip” “D:\new\output” resa

D:\new>setlocal ENABLEDELAYEDEXPANSION

D:\new>set gptPath=“C:\Program Files\snap\bin\gpt.exe”

D:\new>set graphXmlPath=graph.xml

D:\new>set parameterFilePath=resample_20m.properties

D:\new>set sourceDirectory=“D:\new\input_zip”

D:\new>set targetDirectory=“D:\new\output”

D:\new>set targetFilePrefix=resa

D:\new>md “D:\new\output”
A subdirectory or file D:\new\output already exists.

D:\new>for / F in (S2*.SAFE) do ( echo. set sourceFile=~fF
echo Processing !sourceFile!
set targetFile=“D:\new\output”\resa_%~nF.dim
set procCmd=“C:\Program Files\snap\bin\gpt.exe” graph.xml -e -p resample_20m.properties -t “!targetFile!” “!sourceFile!”
call !procCmd!
)

You have to fill the xml and bat files with your own directories, otherwise it would never run. Could you tell us what you want to do exactly?

#4

This is an example.
I want to do a resampling.Can you tell me what the problem is?

#5

The graphXmlPath and parameterFilePath arguments must require the full path (not just the names as you have used). Assuming these files are in the D:\new directory, try:

D:\new>processDataset.bat "D:\new\graph.xml" "D:\new\resample_20m.properties"  “D:\new\input_zip” “D:\new\output” resa
