Problems with imagefilter

[lisar...@gmail.com]

Hi, I'm having an issue with imagefilter on ubuntu.  All other scripts are running fine, and it is not a problem of disk space.  The error I receive is:

(osgeo) lrebelo@Lisa-VirtualBox:~/DATAShare/TANA/SCANSAR_MOSAIC$ python FilterAndMask.py 

*******FILTERING FILE: C004_N00E036_HH_G0

Found 1 filter:

 1) Lee: size = 5 nLooks = 5 

C004_N00E036_HH_G0

Executing filter 1 of 1

Traceback (most recent call last):

  File "FilterAndMask.py", line 20, in <module>

    imagefilter.applyLeeFilter(HHImg, FilterHHimage, 5, 5, 'KEA', rsgislib.TYPE_32FLOAT)

  File "/home/lrebelo/miniconda3/envs/osgeo/lib/python3.5/site-packages/rsgislib/imagefilter/__init__.py", line 813, in applyLeeFilter

    applyfilters(inputimage, outputImageBase, filters, gdalformat, outExt, datatype)

_imagefilter.error: Output image could not be created. Check filepath.

It was running fine (same directory, same script) until today.  I've updated to the latest version of rsgislib but no luck.  

Thanks for any help,

Lisa

Hi,

Are you using the latest version of RSGISLib from conda-forge (3.3.16)?

Can you send what ‘outputImageBase’ is defined as?

Also can you confirm you have permission to write to where the output image is being saved to.

Thank,

Dan

Hi Dan,

Yes, I have permission - and no problems writing from other rsgislib scripts to same directory.

rsgislib is version 3.2.1363 updated just now through conda.

The 'outputImageBase' is a processed ALOS ScanSAR tile, example attached (converted to geotif for ease of attaching) along with script.

Thanks,

Lisa

Hi Lisa,

So the basename for the output image will be:

C004_N00E036_HH_G0_filt

I’m not sure why there would be a problem with this. Can you try creating a file in that directory using:

touch C004_N00E036_HH_G0_filt

If you can create this file try changing the line:

FilterHHimage = HHImg + ‘_filt'

to:

FilterHHimage = HHImg + ‘_filt.kea’

As in add the correct extension for a KEA format file and see if this works.

Thanks,

Dan

Hi Dan,

Yes, I can create the files.  Also when I run the script the file is created, it just does not get written to.  I'm getting the same error on both of my machines (desktop and laptop, both running Ubuntu through Virtual box, and for different file types (e.g. writing to ENVI/Kea/tif)

Thanks,

Lisa
