I'm quite new to GDAL and coding in general. I'm trying to convert a whole bunch of TIFFs to ECW's, but just wanted to test with one to start however I think I might be having problems with syntax. I run the below.bat file but nothing happens.

REM"C:\OSGeo4W\bin\gdal_translate.exe" -of GTiff -of ECW 440554775.tif 440554775.ecw

    What do you think the REM accomplishes here?

  • You have provided two outputformats -of GTiff -of ECW. That does not make sense.

In DOS/batch REM is a comment or a remark. It means ignore everything on this line. So your gdal_translate command just gets skipped.

But even if you uncommented by removing the REM, your command would fail as the OSGeo4W ECW package gdal-ecw is read-only:

Write support for ECW and JPEG2000 via the ECW SDK is not available as part of OSGeo4W.
