Hi Jukka and others,
Thanks for the advice, thats how Ill probably do it since our client wont
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 wouldnt be counted as non-commercial (in my case
the client is a municipality).
Im 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. Ive
asked the same question here:
https://gis.stackexchange.com/questions/289780/how-to-transform-raster-in-ec
w-format-to-a-geotiff-with-jpeg-compression-probl
Perhaps youre 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. Im
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 werent enabled. Now were going through the steps once
again trying to troubleshoot the problem. Im 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) Im 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/>
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 Im preparing the Geoserver has handed me some ECW-files
and as far as I understand this has been debuted a bit concerning its
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
dont have a license, but rather a third party data provider has simply
handed the data sets in ecw-format.
Cheers,
Ville Koivisto
