json update needed

The code does not work with the latest Nansat version. The package was installed with conda.

Here the output: /Data/pit000/ResearchData/IFT/EarthObservation/MOSAIC/SAR/Sentinel-1/S1B_EW_GRDM_1SDH_20191016T064336_20191016T064441_018497_022DA3_6888.zip /Data/pit000/ResearchData/IFT/EarthObservation/MOSAIC/SAR/Sentinel-1/S1B_EW_GRDM_1SDH_20191017T040823_20191017T040927_018510_022E09_9E76.zip 20191016T064336 20191017T040823 Time difference: 77087.0 seconds 07:39:54|40|nansat|_get_dataset_metadata|GDAL could not open /Data/pit000/ResearchData/IFT/EarthObservation/MOSAIC/SAR/Sentinel-1/S1B_EW_GRDM_1SDH_20191016T064336_20191016T064441_018497_022DA3_6888.zip, trying to read with Nansat mappers...

I have the same problem, I think the reason is my VPN setting, the first time I running it, it download a file automaticly, but because my internet issue, the progress closed in middle way, I think delete the file and redownload it should work, but I don't know where it is.

[CatherineTaelman]

as in the S1 denoising algorithm instructions, the metadata vocabulary needs to be updated: python -c 'import pythesint as pti; pti.update_all_vocabularies()' . This solved the issue for me.
