Hi Ville,
Something does not seem to match with gdalinfo and the error message. Data type
Byte means 8-bit and it should convert fine into jpeg-in-tiff.

Hi Jukka and others,
Thanks for the advice, that’s how I’ll probably do it since our client won’t
assumable ever get the license from Hexagon. I read somewhere that usage of ecw
on a server would be legal for educational purposes (i.e. universities and
such) and for non-commercial purposes. Unfortunately same source declared that
government wouldn’t be counted as non-commercial (in my case the client is a
municipality).
I’m struggling a bit to convert the ecw to geotiff. It seems to be due to 8bit
data type requirement that JPEG compression has. I get the following error
message in QGIS (raster --> translate [gdal_translate]):
ERROR 1: JPEGSetupEncode:BitsPerSample 16 not allowed for JPEG
ERROR 1: JPEGSetupEncode:BitsPerSample 32 not allowed for JPEG
ERROR 1: An error occurred while writing a dirty block
My ecw has three bands and according to gdalinfo has data type of byte. I’ve
asked the same question here:
https://gis.stackexchange.com/questions/289780/how-to-transform-raster-in-ecw-format-to-a-geotiff-with-jpeg-compression-probl
Perhaps you’re more experienced with gdal_translate?
Kind regards,
Ville Koivisto

Hi,
Have you considered to convert your ECW files into tiled, JPEG compressed
GeoTIFF files? That way you could achieve about the same file size with
slightly decreased quality because of second round of lossy compression. From
my experience the quality loss is harmless. GeoTIFFs have good native support
in Geoserver and you would not need to acquire the ECW license from Hexagon
that is otherwise needed if you want to use ECW files with a server application.
Problems with adding GDAL image formats are quite common. I wonder what should
be done for making the installation easier. GDAL 1.9 is very old and no
software should rely on that version while the current version is 2.2.2.

Aihe: Re: [Geoserver-users] Geoserver on Debian: GDAL-libraries
Good morning,
Thanks for answering. My overall goal is to enable ECW as a file format for my
geoserver (2.13.1) which installed on a server using Debian 9 as OS. I’m
following these instructions:
http://docs.geoserver.org/latest/en/user/data/raster/gdal.html
We followed through the tutorial once with my colleague, but no luck. GDAL
popped up to modules list under server status tab, but it has a warning sign.
New formats weren’t enabled. Now we’re going through the steps once again
trying to troubleshoot the problem. I’m still a newbie when it comes to Linux
and geoserver so it might be something obvious…
Could you point me to source from which you downloaded a proper GDAL library
for Debian? How did you know to use 1.9.2? As I said below, it seems not to be
listed here:
https://demo.geo-solutions.it/share/github/imageio-ext/releases/native/gdal/1.9.2/linux/
Kind regards,
Ville Koivisto

Hello Sir,
I guess I would need to know more what you're trying to do. I may be able to
help a bit? My set up is a bit different , as I am running Geoserver in a
Debian Docker Container, but i am using GDAL 1.9.2 in the container. Maybe i
can be of some help.

Hi everyone,
Apologies if my question is obvious, Linux is something new to me. All tips are
appreciated. I have two questions:
1) I’m looking to install GDAL native libraries for my Linux Debian server. But
Debian seems not to be listed on this download page
(https://demo.geo-solutions.it/share/github/imageio-ext/releases/native/gdal/1.9.2/linux/).
Is Debian not supported for GDAL or what am I missing?
2) A client to whom I’m preparing the Geoserver has handed me some ECW-files
and as far as I understand this has been debuted a bit concerning it’s license.
Can anyone elaborate on usage restrictions of ECW-files on a server environment
as of today? The client is a municipality and intended use is non-commercial
(different definitions of course exist). Assumable, they don’t have a license,
but rather a third party data provider has simply handed the data sets in
ecw-format.
Cheers,
Ville Koivisto
