Thank you so much for the help Hendrik.
I didn't realize that I could use different versions of the bindings with
imageio, I thought I had to use the 1.9.2 bindings that were included.
Once I had your suggestions I was able to easily add a dependency exclusion for
the bindings and include my own:
<dependency>
<groupId>org.geotools</groupId>
<artifactId>gt-imageio-ext-gdal</artifactId>
<version>${geotools.version}</version>
<exclusions>
<exclusion>
<groupId>it.geosolutions.imageio-ext</groupId>
<artifactId>imageio-ext-gdal-bindings</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.gdal</groupId>
<artifactId>gdal</artifactId>
<version>2.2.0</version>
</dependency>
Once I had the java bindings updated, it was very easy to get the GDAL piece of
things installed using apt-get
sudo apt-get install libgdal-java
sudo apt-get install gdal-data
Granted, I aleady had GDAL installed on the machine running things so there may
be other dependencies I've missed.
Thanks again Hendrik

Hi Duane,
we integrated GDAL 2.2.3 successfully with geotools 19, using the following
steps:
* downloaded precompiled binaries
(https://trac.osgeo.org/gdal/wiki/DownloadingGdalBinaries)
* put the java bindings, that correspond with the precompiled binaries on
the class path (gdal.jar)
* delete the old version gdal java binding jar
imageio-ext-gdal-bindings-X.jar, that was shipped with imageio
* put the precompiled binaries in one of the standard gdal driver paths or
set environment variable
(https://trac.osgeo.org/gdal/wiki/ConfigOptions#GDAL_DRIVER_PATH)
* check, if declaration of gdal_data is needed on your operating system
(https://trac.osgeo.org/gdal/wiki/ConfigOptions#GDAL_DATA)
Then you should see something like this:

Betreff: [Geotools-gt2-users] gt-imageio-ext-gdal
I'm attempting to use the following dependency to read a file in the DTED
format.
<dependency>
<groupId>org.geotools</groupId>
<artifactId>gt-imageio-ext-gdal</artifactId>
<version>20.1</version>
</dependency>
>From what I can tell, gt-imageio-ext-gdal is dependant on

Looking at the imageio-ext project, version 1.1.27 was released October of 2018
and does in fact include 1.9.2 native libraries in its release. However, all of
the precompiled binaries are for older OS versions. Redhat 6 is the newest OS
represented and I can't seem to find precompiled binaries anywhere for RHEL7 or
newer versions of Ubuntu.
I notice that GDAL is well past 1.9.2 and is already deploying version 2.2+ as
part of apt-get/yum, but using newer versions of the bindings does not appear
to work since I get this stack trace if I try.

Is there some other way of acquiring the bindings at this point, so people have
stopped deploying against newer OS or should is the normal process to compile
the bindings yourself?
