Re: [Geoserver-users] Some map layers not drawing with 2.1.1

[Andrew Walsh]

Hi Phil,

Thanks for noticing. Good to know there are other ARCSDE data
store users out there. Can't figure this one out yet and its weird
that other ARCSDE layer draw up OK at first e.g the ran:xbt,
ran:beach_temp and ran:seabed are OK but other 2 ran:biolum
and ran:secchi are not.

Can't really go over the POSTGIS as we are stuck with
ESRI-ARCSDE.

Couple of other things I might experiment with:

1) Delete and re-publish the ran:biolum and ran:secchi layers.

2) Try viewing the layer with another WMS viewer such as Gaia.

Thanks and Regards,

Andrew

Well I am pumping out some pretty huge datasets via geoserver, but the 
drawing is done WMS. When you talk about performance degradation with 
3000 pts, it sounds like you are using WFS which is definitely too slow. 
You want to draw with WMS (where you have server-level hardware doing 
the drawing using fast code not javascript and where tile caching can 
further improve performance), and WFS for querying. If you look at the 
SLDSelect example in openlayers, you can even use WMS for drawing the 
selection but geoserver doesnt honour SRS in the SLD (mapserver does) so 
you have to deal with that in the client.

Re: [Geoserver-users] Advanced logging questions

[Charles Galpin]

I started tomcat using the startup script (instead of as a service) and it did 
indeed copy the logging profiles to the $GEOSERVER_DATA_DIR/logs directory so 
it seems it's a difference in working directory on startup as a service.

[Geoserver-users] How do you handle large amounts of data?

[Tito, Joseph]

I'm  trying to expand one of my  current application (using OpenLayers)
to handle larger amounts of data. Right now the application comfortably
handles 2,000-3,000 points at a time, but I'd like to expand its
capabilities to handle at LEAST 20,000 points (hopefully using
GeoServer).

 

The main problem I have is when a user views an area on a map that has
more than 2,000 points, performance is severely degraded. I was
wondering if GeoServer could help with this in some way. If a particular
area has 5,000 points for example, is there a way to group that
information into clusters with GeoServer. So the browser only thinks
there's 2,000 points, but those points represent the 5,000 you should be
seeing?

 

I've heard from multiple people on the OpenLayers mailing list that
GeoServer can help, but nobody has explained how. If anyone could lend
some advice on how you handle large datasets with GeoServer, I would
greatly appreciate it.

 

Thank you

 

Joe Tito

Re: [Geoserver-users] Image pyramidal plugin

[Jim White]

Hi Daniele,

I tried the os-independant binary and it didn't work too well and 
reinstalled the geoserver.war and found that I had had 2 problems.  I 
needed to add a srs to gdal_retile.py, but I found that it still  didn't 
work and I had to add the attribute to

JreMemoryLeakPreventionListener.

I have another question about tomcat and geoserver. When I add the -user 
tomcat switch to the tomcat startup script geoserver will not start, 
although tomcat does. It might be related to writing in the /tmp 
directory. Is this a known issue?

It would be useful to better understand the origin of this error.
Moreover, using that Tomcat version, I would take a look at the tip

the plugins are deregistered and therefore geoserver is unable to find

Please, let us know.

[Geoserver-users] Advanced logging questions

[Charles Galpin]

For some reason I didn't see the production logging profile under the logging 
profiles on the global settings page which sent me looking for the log4J files 
so I could add one because they were not under $GEOSERVER_DATA_DIR/logs (this 
is a .war deployment) .  I finally found them under the tomcat logs directory 
but this left me with a couple of questions before a submit  some small edits 
to the advanced logging documentation.

1. Do these logging profiles get copied/generated to the tomcat log directory 
on the first deployment if they don't already exist or something?  I assume 
this would be container independent?

2. The docs mention overriding the log location and name by setting the 
GEOSERVER_LOG_LOCATION parameter but I see this as an option on the global 
settings page. Is using the GEOSERVER_LOG_LOCATION parameter now obsolete, or 
still an option if for some reason you don't want to set it in the global 
settings? Which overrides which?

I'll make the docs clearer on these issues once I understand them better.

thanks,
charles

The standard parallels are, geometrically, the place
where the cone intersects the earth ellipsoid:

[Geoserver-users] Geoserver CRS description bug

[Dmitriy Tyugaev]

Hi all,

I have a bug when I add new coordinate system to my Geoserver 2.1.1. For
example I add ESRI:102012 from spatialreference.org with next WKT string:

PROJCS["Asia_Lambert_
Conformal_Conic",
GEOGCS["GCS_WGS_1984",
DATUM["WGS_1984",
SPHEROID["WGS_1984",6378137,298.257223563]],
PRIMEM["Greenwich",0],
UNIT["Degree",0.017453292519943295]],
PROJECTION["Lambert_Conformal_Conic_2SP"],
PARAMETER["False_Easting",0],
PARAMETER["False_Northing",0],
PARAMETER["Central_Meridian",105],
*PARAMETER["Standard_Parallel_1",30],*
*PARAMETER["Standard_Parallel_2",62],*
PARAMETER["Latitude_Of_Origin",0],
UNIT["Meter",1],
AUTHORITY["EPSG","102012"]]

... but when I look at CRS list in Demo page the values from
'standard_parallel_1' and 'standard_parallel_2' are exchanged.

PROJCS["Asia_Lambert_Conformal_Conic",
  GEOGCS["GCS_WGS_1984",
DATUM["WGS_1984",
  SPHEROID["WGS_1984", 6378137.0, 298.257223563]],

AXIS["Longitude", EAST],
AXIS["Latitude", NORTH]],
  PROJECTION["Lambert_Conformal_Conic_2SP"],
  PARAMETER["central_meridian", 105.0],
  PARAMETER["latitude_of_origin", 0.0],
  *PARAMETER["standard_parallel_1", 62.0], *
  PARAMETER["false_easting", 0.0],
