Re: [Geoserver-users] Null namespace in WFS response for layer based on disabled PostGIS store [SEC=UNCLASSIFIED]

[Johnson, Steven (Contractor)]

UNCLASSIFIED
Thanks for your help Ben and Andrea.

I guess the null namespace issue is a bit of a moot point anyway given that the 
WFS should not be serving features when the store is disabled.

We'll take your advice Ben about monitoring and re-enable the datastore via the 
REST API if indeed the store is available but disabled in GeoServer.

Andrea, I am sure you are right. I have closed this one as duplicated by 
GEOS-7792 (which links to this thread and the fixes for disabled layers). I 
note that I did not see the null behaviour in my tests with WFS 2.0 / GML 3.2.

Interesting, I've tried a similar path to the one that triggers the wfs 1.1 
null prefixes, but using the wfs 2.0 protocol, and I indeed could not reproduce 
either... not sure why?
This is what I've tried, on a freshly start up GeoServer:
http://localhost:8080/geoserver/topp/ows?service=WFS=2.0.0=GetFeature=topp:tasmania_cities=1

[Geoserver-users] Reprojection is not working in Image Mosaic

[Jin Ho Jo]

Hi,

I am newly set up Image Mosaic Store/Layer on Geoserver and trying to make it 
work.
And I can get images from Image Mosaic, but have an issue which is image 
reprojection is not working.
Image appears in designated location on the map correctly, but it is just flat 
image, not reprojected.
It is correctly reprojected in regular browse image layers.

I am working on Image Mosaic Layer on Geoserver 2.9.0 and Openlayers2, Java 1.8 
on Windows 7.
And using EPSG:4326, and set USE_JAI_IMAGEREAD as 'false'.

Sample image not projected is attached.

Can you please check this and what is needed to make it reprojected?

Thanks
Jin

Re: [Geoserver-users] Native JAI

[Rini.Angreani]

Hi Andrea,


Thanks for your help. I also found the log in GeoWebCache and did a comparison 
with non populated tile cache :-).

I thought I would double check by asking the list to cover all the bases - in 
case it's used elsewhere.

Thanks again.

Subject: Re: [Geoserver-users] Native JAI

Hi Rini,
that log is actually from GeoWebCache, so a proper performance comparison 
should be done
by hitting a non yet populated tile cache and force GWC to popupate it... like 
a seeding operation
for example.

That said, the JAI "crop" operation is actually doing nothing, it's just making 
the image look smaller
to the callers by changing its origin, width and height (thus metadata),
so I don't see how a native extension can make any difference. From the javadoc 
of CropOpImage:

 *  Tiles that are completely inside or intersect the cropped region
 * (this image's bounds) are simply forwarded from the source.  Do NOT
 * create a child raster even if a tile is not contained in this image's
 * bounds.  Tiles that are outside the croppped region result in a
 * null return.

My guess is that the comment actually relates to an issue in the Java JPEG 
encoder that fails
to encode properly shifted images (ones with origin not 0,0). However this 
should have been
fixed in the meantime.
Simone, do you remember any better?

To see if the code still has any merit, one should try to remove the 
BufferedImage extraction code here
and see if that actually makes any difference:
https://github.com/GeoWebCache/geowebcache/blob/master/geowebcache/core/src/main/java/org/geowebcache/layer/MetaTile.java#L319

It is also to be noted that GeoServer is using its own metatile subclass, with 
entirely different code, it would be nice to just push back
the override, but I'm not 100% sure it's possible (due to dependencies that 
might be available in GeoServer, but not in GeoWebCache):
https://github.com/geoserver/geoserver/blob/master/src/gwc/src/main/java/org/geoserver/gwc/layer/GeoServerMetaTile.java#L162

But yeah, in the context of GeoServer that warning is just noise, since the 
code depending on that variable is not even executed.

Cheers
Andrea

[Geoserver-users] Hexagon Binning

[Volkan Gümüs]

Hello everybody!

I'm looking for a way to overlay my WMS layer with a layer that is 
binned through hexagons. I'd like to set an edge length (let's say 
300meters) and receive hexagons for the whole map.

Is there a way to get this kind of hexagon layer without the need to 
create previously all hexagons as postgis objects?

I'd like to achieve this without geometry creation or at least only 
using lazy geometry creation (on demand).

Thank you!

[Geoserver-users] ImageMosaic with predefined projection

[Arnaud L.]

Hi all,

I'm migrating a bunch of our services and data to GeoServer (2.8.4, 
Windows).
We have a quite large raster store here. It consists of some hundreds of 
thousands of TIFF files with their accompanying TFW worldfile.
They are all in the same projection.

I thought it would be easy to configure an ImageMosaic with this data 
since all the needed information is already stored in a PostGIS 
database, but I have an issue because our TIFFs are not GeoTIFFs, and 
they also don't have a PRJ file.

I could create a PRJ file for every TIFF, but that would mean a lot of 
wasted space (and time). I could also convert all of them to GeoTIFF, 
but that's a hard work. I have yet to find a tool that *modifies* a TIFF 
to make it a GeoTIFF. All the tools I've found make copy of images (i.e. 
  create a new GeoTIFF file instead of converting the TIFF to GeoTIFF).
This does not integrate well in our processes at all.

Is there a way to setup my datastore so that GeoServer doesn't look for 
a PRJ file and just uses a projection that I would hardcode somewhere ?

Thanks a lot for your help !
Arnaud

I remember having a similar issue that I worked through. Now I can ingest tiles in real time and see updates immediately to the layer. 
 

I believe it was this setting in the indexer.properties file:

 


# (Optional) A boolean flag to disable/enable caching. When enabled the ImageMosaic will try to pin in memory the entire content of the index to reduce loading/query time. If we have a large granule index and/or we want to ingest in real time new granules (e.g. the index is on a database and we interact directly with it) we need to disable caching, otherwise we can enable it.

Caching=false

Hm. I may be wrong, but this sounds like a bug. You might consider filing a report.

If you update the underlying data frequently in the work that you do and can't wait on a bugfix, I would try to determine what else forces an update, such as clearing Geoserver's cache for the layer, etc ( potentially relevant: http://gis.stackexchange.com/questions/77240/ ) . (Obviously, you've found that deleting/recreating the layer does the trick.) From there, you may just automate this, and arrange to clone/delete/remake/empty the cache for the layer using Geoserver's configuration REST API, and have this happen either periodically or whenever you make edits from your database.

[Geoserver-users] Native JAI

[Rini.Angreani]

Hi list,

We notice a warning about Native JAI not being installed in the log files. I 
did a simple WMS GetMap performance comparison with and without native JAI, and 
they seem to be pretty much the same. Does anyone know if/how native JAI affect 
performance?

WARN [layer.MetaTile] - * Native JAI is not installed, meta tile 
cropping may be slow 

Thanks
Rini
