Re: [Geoserver-users] problem with imagecollection plugin

[Garey Mills]

Andrea -

Thanks for the info. I downloaded gdal-1.7.3 and installed it as 
suggested. I am now getting this error:


Oct 27, 2011 1:42:35 PM 
it.geosolutions.imageio.gdalframework.GDALUtilities loadGDAL
WARNING: Failed to load the GDAL native libs. This is not a problem 
unless you need to use the GDAL plugins: they won't be 
enabled.java.lang.UnsatisfiedLinkError:

in /usr/lib I have

libstdc++.so.6.0.8

What's the best way of getting gdal working from here?

Thank you. Commenting out



in server.xml worked!

Now the next thing I want to do is to make the Imagecollection
plugin work with MrSid images. Does anyone have any idea what the
steps would be to do that? In the imagecollection module, the only
mention of formats seems to be in Utils.java where the code checks
the file extension. However, though I add in '.sid', there, when I
try to publish a MrSid image, MrSid is not one of the image
formats that show up.


Hmm... do you have the support to read MrSid files to start with?
It's part of the GDAL data sources, requires the right GDAL native 
libs to be installed, distributed

along with imageio-ext itself.

Anyways, don't know if having those is sufficient.. but for sure if 
don't have a MrSid store showing
up in the store list when you try to create a new store you won't be 
able to open a .sid file

Oh, that's good to know. But what geoserver version were you using? if
2.1.x it should work with Java5, otherwise we have a problem. If 2.2.x
then you actually need Java6 afaik.

Reprojecting to 4326. Since reprojection is involved, it is imperative that
your data native CRS is setup properly

[Geoserver-users] Question about generating KML files

[António Rocha]

Greetings

I have one question tregarding how Geoserver generates KML files for 
layers: Since KML data must be in EPSG:4326 and my data is not in that 
system, what is geoserver doing to generate KML? Reprojecting data to 
EPSG:4326 and then generating KML or diretcly converting to KML 
coordinates without reprojecting?
Thanks
Antonio

Re: [Geoserver-users] User permissions issue - unix install

[christian . mueller]

First, check under which user tomcat is running. For linux, this can be done
with

ps -ef | grep java

After you get the user, make

chown -R  /deploy/geoserver/tomcat_6.0.29/webapps/geoserver/data

On linux, this changes the owner of the GEOSERVER_DATA_DIR recursivly.

Remark: The user you use for administer Geoserver has nothing to do  
with the unix file permissions.

Hope this helps.
Christian

[Geoserver-users] User permissions issue - unix install

[appela]

Hi all, 

We are experiencing a problem I have not faced before.

Example: 
I have a user role as administrator within the admin UI
I can create a new Store just fine. 
If I go back to make a change to the Store, say update max connections or
something like that I get an error saying 
java.lang.IllegalArgumentException: Error saving data store:Error persisting
DataStoreInfoImpl[gerpostal] to
/deploy/geoserver/tomcat_6.0.29/webapps/geoserver/data/workspaces/globalpostal/gerpostal/datastore.xml

The user that 'owns' the datastore.xml file is the user that manages the
machine that geoserver is running on, while the folders created within the
gerpostal folder belong to someone else.

What dictates who owns what when geoserver generates the folders and files
upon creation of stores, layers, etc?

This is becoming troublesome since we can't edit anything we have already
created.

thanks in advance.

Tony

HI all

Now I need to create layers automatically, since my application needs to
create for each logged in user separate layers in Geoserver, which are

I assume this is done via invoking some services or Servlets of
Geoserver. Is there a way to do that or is there any documentation

Do you mean logging in and out of GeoServer or an external application?

If it's an external application you should look into  "rest configuration":
http://docs.geoserver.org/stable/en/user/restconfig/rest-config-api.html

If it's the GeoServer GUI instead... I don't know if it can be done at all,
but these users would be administrators and thus see everything and
the "remember me" cookies would make it hard to tell about an actual
logout.

you might see if this is related to your problem:

It is, however, very possible to create an OpenLayers application that

[Geoserver-users] Geowebcache in openlayers problem

[Robert Buckley]

hi,
This is a follow up of my previous attempt to understand how to use 
geowebcache(gwc) and use openlayers to visualize data.

I have been having problems with gwc and EPSG:900913 in openlayers. I want to 
serve raster data over googlemaps, but cannot get geowebcache to work together 
with openlayers in EPSG:900913

As a test, I have set up test layer called wgs84Point which is a postgis layer 
with 3 points digitized in wgs84(EPSG:4326). I have fed it into geoserver and 
have build two clients to visualize the points. One of the clients has a map 
set up in wgs84 (EPSG:4326), the other identical map with Google (EPSG:900913).

http://maps.zgb.de/eeg/wgs84.html


http://maps.zgb.de/eeg/900913.html


Both maps contain the wms version of the points layer and also the geowebcache 
version.

As can be seen, the WGS84 EPSG:4326 version lines both the wms and geowebcache 
points perfectly.

from the geowebcache demo page in geoserver I can view the layer in both 900913 
and 4326

here is one tile in EPSG:900913
http://maps.zgb.de/geoserver/gwc/service/wms?LAYERS=zgb%3Awgs84point&FORMAT=image%2Fpng&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A900913&BBOX=1164288.8146777,6946597.1295898,1169180.7844873,6951489.0993994&WIDTH=256&HEIGHT=256


and the same point is EPSG:4326
http://maps.zgb.de/geoserver/gwc/service/wms?LAYERS=zgb%3Awgs84point&FORMAT=image%2Fpng&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A4326&BBOX=10.532455444336,52.833938598633,10.533142089844,52.834625244141&WIDTH=256&HEIGHT=256



My Geoserver logs are giving me this...

2011-10-27 14:39:21,406 ERROR [geowebcache.GeoWebCacheDispatcher] - X,Y values 
for the tile index were calculated to be {1081.4697265626, 1380.0979003904074}  
which had to be rounded to {1081, 1380}  and exceeds the threshold of 10%. 
Perhaps the client is using the wrong origin ? 
http://maps.zgb.de/geoserver/gwc/service/wms


which corresponds to the firebug output for the pink tiles..400: X,Y values for

which had to be rounded to {1081, 1376} and exceeds the threshold of 10%. 
Perhaps the client is using the wrong origin ?

So I really don´t know where to look for solutions.

Any help is most welcome

Re: [Geoserver-users] Geowebcache.xml problems

[GeoGEOrge]

Thank you for your help. I have been feeling very stuck and would really like
to be able to use geowebcache.
I added -Xmx512m -XX:MaxPermSize=256m to my geoserver-2.1.2/bin/startup.sh
and 
I substituted the gridSet you supplied (it complained until I moved the
metersPerUnit after scaleDenominators) 

I still get what appears to me to be the same message and geoserver doesn't
work:

Re: [Geoserver-users] Memory Problems in access to reprojected image mosaics

[DGIS Devels]

Geoserver Version :  2.1

We have tried -Xms1024M -Xmx1024M -XX:PermSize=256M but the behavior is the
same.
Although -Xmx1024M is set,  the memory size is increased more than 1,8G (we
use "ps -e -orss=,args= | sort -b -k1,1n | pr-TW$COLUMNS"  to know how much
memory  every process uses ) . The remainig memory is cached by S.O but we
have clear the cache to allow JVM to use this memory.If we don't clear the
cache, messages like this appear:

"Java HotSpot(TM) 64-Bit Server VM warning: Attempt to deallocate stack
guard pages failed.
Java HotSpot(TM) 64-Bit Server VM warning: Attempt to protect stack guard
pages failed.
mmap failed for CEN and END part of zip file"

"Errores : java.io.IOException: No memory left for cache!  at
javax.imageio.stream.MemoryCache.pad(MemoryCache.java:171)"


We have found others errors like :  "java.lang.OutOfMemoryError: GC overhead
limit exceeded" . We have used -XX:-UseGCOverheadLimit to avoid GC working
too much


We have been  testing 256x256 tiles ( stress test during 18 hours , 150
concurrent users, 2.314.321 resquests  ).Total Size memory =1.3G without
OOM.Now,we are working with 850x1064 images and a lot of OOM appear.


Thanks in advance

[Geoserver-users] Calculate BBox (width/height) based on image size, scale and center of original BBox

[zorg]

Hi,

I send to geoserver (http://my_ip:80/geoserver/wfs) this query:





Myworkspace:idpar
Myvalue





I get the coordonnate of BBox, therefore I can determin the center of my 
bbox.

(Projection : EPSG: 3945)

I want to print in a pdf an image (example: size 500 pixel * 450 pixel 
and 96 dpi ) with specific scale (1/1).

How do I calculate the new BBox?

Thanks

Doh, I fist looked into the docs and could not find the "change" thing, then
noticed
it's in the page itself :-p

I think it's just a mistake, don't remember ever having a change button in
that page (maybe it was
in the 1.7.x series? can't remember honestly).
What the description could say is that you can change the request url and
body, play with it, before
submitting.

Re: [Geoserver-users] Failed attempts at using geowebcache

[Rahkonen Jukka]

Ok, in that case the source rasters in EPSG:4326 should be OK.
When I have faced misalignment problems with GWC and OpenLayers they have 
always been because GWC and client had somehow different settings for 
scales/resolutions. But it should not happen easily for you because you are 
using the standard EPSG:4326 and Google grids.
You could do another try with a less error-prone client than OpenLayers, but it 
would mean using uDig. It has a setting to read maps from from your GWC through 
WMS-C (tiling WMS server) system.  UDig is reading the tiling schema from your 
GWC and then there should be one opportunity less for things going wrong.
