Do you need to read a czml or produce it? If read, Brad's answer is on the
spot, otherwise
you'll need to build a new output format, see the
https://github.com/geoserver/geoserver/blob/master/src/wfs/src/main/java/org/geoserver/wfs/WFSGetFeatureOutputFormat.java
base class and all its subclasses

Only GeoServer 2.16.x supports GDAL 2.4 officially. GeoServer 2.15.x should
go with 1.9.2, even if there are people that managed
to make it work with 2.x too (but not officially supported)

The GDAL readers have no support for masks yet, it's present at the GDAL
level but not exposed through the Java API
GeoServer is using yet (via imageio-ext). Support is possible but
coding/funding is needed to make that work.

The NPE happens when no data could be read from the raster, the real issue
is happening before this trace.

If the masks are internal to the geotiff you might want to try out skipping
the VRTs and using this (community, thus unsupported) plugin
to read directly from the remote site (not sure if it will work on Azure
blobstore, maybe not, but I'll share it for you to try):

https://docs.geoserver.org/latest/en/user/community/s3-geotiff/index.html

Generally speaking, the path you're trying to take needs some development
to work properly, I'd suggest you get in touch with
a commercial support provider: http://geoserver.org/support/

Re: [Geoserver-users] Geoserver does not start up again after tomcat-restart

[Andrea Aime]

Hi Uwe,
the logs you shared are part of the shutdown and you'll find them in any
case, even when the startup succeeded.
Can you share a full log of a failing startup, from the beginning?

Re: [Geoserver-users] Geoserver does not start up again after tomcat-restart

[Humphries, Graham (StateGrowth)]

Just to add my 2c worth

Don’t install your data files into the /tomcat/webapps/geoserver/data 
directory. Host your data elsewhere on the file system.

You can change the value for GEOSERVER_DATA_DIR in the web.xml file in 
/tomcat/webapps/geoserver/WEB-INF directory to point to this location.

Eg:
   
   GEOSERVER_DATA_DIR
/opt/spatial/geoserver/data


This way you can:

· Install your new instance of Geoserver and check that it works.

· Stop Geoserver

· Change the web.xml file as outlined above

· Start Geoserver.


All your data should now be available

Re: [Geoserver-users] Absolute URL paths in clustered Geoserver's settings

[Adam Borczyk]

Actually the problem was in proxied headers and I did not think this would
be the case, but I fixed it accidentally doing some other task. Anyway, one
should just add those headers in Nginx:

proxy_set_header Host$host;
proxy_set_header X-Forwarded-For $remote_addr;

Sorry for cluttering here.

Best regards

[Geoserver-users] Absolute URL paths in clustered Geoserver's settings

[Adam Borczyk]

Hi everyone!
I set up a dockerized Geoserver cluster, where I have one Master node and
multiple Secondary nodes. They share config using JDBCConfig. In front of
them I have Nginx, that redirects every request in administrative panel to
"Master node" (with rule that does proxy_pass if path starts with
"/geoserver/web") and every other requests to "Secondary nodes".

I noticed that in the admin panel of Geoserver, most links are to relative
URL (in my case it takes "localhost/"), but in some parts they point to
my Docker container's hostname, eg. with Layer Preview "
http://geoserver-master:8080/geoserver/nurc/wms.";.

As there is no connectivity straight to the container, this request
obviously fails. How can I approach this? Do I have to explicitly specify
Geoserver's hostname? Or maybe there is a way to make it relative like
"/geoserver/nurc/wms." and resolve automatically through Nginx?

Best regards

[Geoserver-users] NearestNeighbor and GeoWebCache producing bad quality tiles

[Maik1 via Geoserver-users]

Have setup GeoServer to work with GeoWebCache. Apparently, I have applied
most of the tweaks for improving performance and quality, but still have
rendering issues when using Nearest Neighbor interpolation or GeoWebCache:

Summarizing, I have:

 - Enabled direct integration with GeoServer WMS, tiled=true..etc
 - Enabled the fullWMS mode, using hints=quality parameter in the URL

I have been using Bicubic interpolation because this produces good results
for basemaps when viewed as WMS. This is what I get when using WMS+Bicubic:
 

However, when using Nearest Neighbor+WMS, a white line pattern shows up. So
lines and labels seem to be "split". This is only a slight change but it
makes the map pretty much unreadable:
 

Now, when moving to GeoWebCache with Bicubic interpolation, I expected to
get the same good results as Bicubic+WMS. However, it turns out that I have
exactly the same rendering issue when using GeoWebCache.

My guess is that I am doing something wrong in the layer setup that
generates the rendering issue both in NearestNeighbor+WMS and
GeoWebCache+whatever interpolation method used.

If possible, I would like to use NearestNeighbor because it requires less
resources. I think that if I can get the rendering issue with
NearestNeighbor sorted, then the results will be good in GeoWebCache as
well. BTW, the rendering issue happens also when using Bilinear method.

Can anybody provide some feedback on what I'm doing wrong with this basemap?
