Re: [Geoserver-users] WCS_2.0.1

[bradh]

I don’t think there is any way to do this without code changes on the geoserver 
side. You could modify your client, or use a rewriting proxy.

 

You should be careful about making changes that will make the XML different to 
that expected by standard clients.

The behavior described in the comments might be actually happening...
sorry, no time to
look into it right now, we have the JDK11 code sprint incoming and all
spare time is going there.
I checked the ticket tracker, found no bug report about it.
I would be useful if someone could verify, maybe using a built-in demo
dataset.

Fixing it right now might help, but it will take many years before older
versions of GeoServer
out there are upgraded, we get a surprisingly high number  people running 5
years old versions of GeoServer
asking questions on the list just saying, even if one rushes to fix it
now, that code in QGIS might
not be lifted anytime soon (but it could be made configurable I guess?).

Also, in GeoServer WCS 1.0 normally uses overviews when available, but of
course the layer
might not have them, or be a mosaic of many files. That said, the WCS being
queried is not a GeoServer,
not sure how it might work.

Finally...  any chance QGIS could be using WCS 2.0 instead? The 1.0 and 1.1
protocols are ancient and pretty clunky,
WCS 2.0 is so much better from all points of view.
In fact, I believe that WCS 1.0 and 1.1 have received little to no
significant maintenance
in GeoServer for the longest time, I'd venture to guess very few care about
them.
WCS 2.0 is instead receiving interest and more care, likely because it has
been chosen by INSPIRE
for raster download services.

Cheers
Andrea

Maybe QGIS detects the background color black as to be transparent?
In the Geoserver ImageMosaic plugin you can map an inputcolor to be
transparent.
But this is not possible in the Geoserver ECW plugin.

What do you use instead of ECW for rasters that is not too big, time and
memory consuming?

Thanks,
Ron

Re: [Geoserver-users] WFS protect server from overcapacity by enforcing BBOX in requests + limiting max BBOX area

[Andrea Aime]

Hi,
the WFS protocol has no way to advertise limits on the bounding box, so
trying to apply them would break
any "standard" client, only clients hand-crafted to work against our
service would be able to reliably extract information
out of it.

The WFS protocol choice to avoid overloading the server is limiting the
number of features returned, and let the client
resort to paging if they cannot get all they want in one shot.
In GeoServer that setting is found under the "WFS" service configuration,
and normally set to a high value, like 10 millions
features, because the way GeoServer operaters is "streaming", meaning it
never loads the whole result in memory,
it reads a page of features, encodes them in GML and sends them out, reads
another page, and so on until the end.
Typically all you need to avoid being overwhelmed is enough database
connections, since they are kept open during
the whole output writing process.

Since you are setting up for production, I'd suggest to also have a look at
these contents:

[Geoserver-users] WFS protect server from overcapacity by enforcing BBOX in requests + limiting max BBOX area

[Julien Laurenceau]

Hi,
I would like to protect my WFS server from overcapacity and thus I would
like to be able to be able to tune the maximum "cost" of a single request.
I already have a way to rate limit the number of calls so that once I'll be
able to tune the maximum cost of a single request it will be easy to
protect my server from overcapacity.

The easiest way that I can think of would be :
- to force users to define BBOX in their requests
- to be able to limit a maximum BBOX area on the server.

I saw that the geofence extension is able to crop the visible area to some
regions, but this is not what I want.
I would like everything to be visible to users, but I would like to force
users to perform several requests when they would like to retrieve a lot of
features with WFS.

Thanks and regards
Julien

Re: [Geoserver-users] Why is footprint shape file necessary in Geoserver and not in QGIS for ECW file?

[Andrea Aime]

Hi Ron,
no clue, I was under the impression that ECW files had no transparency
information... but
I haven't really looked much into it, server side usage of ECW requires an
expensive licence
to be done legally, so we normally just don't use it.

Can you run a gdalinfo on your file?

Cheers

[Geoserver-users] Why is footprint shape file necessary in Geoserver and not in QGIS for ECW file?

[Ron Lindhoudt via Geoserver-users]

When I open an ECW file in QGIS then the black background of the ECW is
automatically made transparent.
When I add the same ECW in Geoserver via ECW plugin then the background is
black and not transparent.
Also if I change the footprint behavior to "Transparent". I have to make a
shape footprint file with the same name as the ECW file to make the black
background transparent.
Is it possible in Geoserver to make the background of an ECW fie transparent
without making a footprint shape file?

The problem was that the layer was created via the REST API without the entry
