GeoServer

Hi,

I have developed an application using Google Maps API for Rajahmundry
Parliamentary constituency. Here is the link for it
http://osgeo.in/google/sample.htm It contains a spatial query interface at
the top and after querying the database it shows the result. I would like to
develop same application using GeoServer with similar interface. Is it
possible to develop it? How can I query to the database and show result on
OpenLayers client with Google background data. I am very much clear about
uploading the data into database and configuring it with GeoServer. I am
just can not able to get at OpenLayers part to develop interface which I
developed earlier. I am also aware with basic things of Openlayers such as
switching on and off of multiple layers etc. Please guide me.

Thanks & Regards,

Santosh Gaikwad

Hi,

I recently installed GeoServer 2.0 (read:newbie) and I am trying to change
the data directory. When I change the directory I get a HTTP Error 503 -
Service Unavailable error when accessing the GeoServer Web Admin.

Here's what I've done:

1. Stopped GeoServer service
2. Copied the data_dir folder from the default location to where I want it
to be
3. Changed environment variable GEOSERVER_DATA_DIR from 'C:\Program
Files\GeoServer 2.0.0\data_dir' to the new directory
4. Started GeoServer (confirmed in services and the log file that it was
indeed started)
5. Opened GeoServer Web Admin page but instead received HTTP Error 503 -
Service unavailable
6. Changed GEOSERVER_DATA_DIR back to 'C:\Program Files\GeoServer
2.0.0\data_dir' and no error

We are running Windows Server 2003.

Any help with this issue would be appreciated!

Cheers,

Shannaka

Ahhh,  The new location was not in the docs yet.  I figured I was missing
something.  For the general user, this type of information probably isn't
needed, or available, however because of the nature of the data I deal with,
I actually do have all of this information, it's just a matter of getting it
to display.

I'm now looking at creating a WFS that I display as a transparent set of
polygons created from the Image Mosaic shape file.  In this case the
GetFeatureInfo response is created from the attributes within the shape
file.  By writing meta data to the shape file during processing, I think I
will get the desired result.

I may look into writing something to make this work on the fly.  I can see a
solution where each image in a mosaic would have a meta-data xml file
containing some set of attributes.  Then either in response to the
GetFeatureInfo call the XML files would be read, or during the creation of
the Shape file the XML would be read.  Either way, a response would be
generated without having to resort to a WFS.

Thanks,
Mark

Paul,
you should open a bug report at jira.codehaus.org and provide a 
reference to this thread or else (and better) provide some requests
that are failing against our sample data (or provide your data) so
that we can reproduce the issue.

Most developers are busy or recovering after FOSS4G and we cannot
act on this one right now, a bug report will make sure we don't
forget about this.

Cheers
Andrea

Hi all,

I'd never seen the styler in action before FOSS4G - it was working quite well in the workshop but I can't for the life of me get it working here.

Using a clean GS 2.0 (war) installation with REST plugin I downloaded styler version 1.7.3 and extracted it to the www directory as per the instructions at http://geoserver.org/display/GEOS/GeoExt+Styler.

Opening up index.html yields two errors in Firefox 3:

GeoExt.ZoomSliderTip is not a constructor
[Break on this error] var Styler=Ext.extend(Ext.util.Observabl...
capabilities.capability is undefined
[Break on this error] var Styler=Ext.extend(Ext.util.Observabl...

So I tried including GeoExt.js and the first error went away... but now the second one is still hanging around.

I tried with Styler for Geoserver versions 1.7.1 also, and tried my own build from svn. It all turns out the same.

Are there any known issues using the styler with Geoserver 2.0?

WFS is about retrieving data, it has no notion of scale, which to have
a meaning requires something to render the data onto a screen or a sheet
of paper.

Whatever is doing the rendering will have to compute the scale, GS does
not offer that kind of service

Hi,

thanx for pointing out my mistake, now its looking prety good, think that
should be put into documentation?

It is not extreme. Users asked unique columns to be treated as primary 
keys in absence of a valid primary key, and provided a patch to 
implement that.

The patch was integrated into GeoServer 2.0 and that is why you're 
seeing the different behavior.

We could add a flag to the datastore to return the primary key columns
as normal columns, and probably make the feature type read only in
that case. It just requires some significant rework in the datastores.

Opened a jira issue against the JDBC-NG datastores to track that:
http://jira.codehaus.org/browse/GEOT-2812

There is no need for pk over views, that's a trick needed only for 
people that want views and also want them updatable (via triggers), 
something that actually works only with Oracle right now.

But 2.0 requires one to register all of the views in the 
geometry_columns table as if they were tables so that the nature
of the geometric column and its native srid can be assessed.

The old postgis connection had some heurisitics, basically if the
info could not be found in geometry_columns it read the first geometry 
out of the table and assumed (hoped) that all of the other rows had
the same geometric type and srid.

This issue is likely due to http://jira.codehaus.org/browse/GEOT-2664

Looks like a bug indeed, but I need to spend some hours on it to figure 
out what is going on. I could not find any open jira issue so I've
created a new one:
http://jira.codehaus.org/browse/GEOS-3613

Actually the EPSG modules do not contain a sql file anymore, but a 
zipped database. The SQL file there is used only when updating the
zipped database itself.

Anyways, it's fine to connect to a ready made DB in the temp directory
and edit its contents, it should work fine as long as the temp directory
contents are not wiped out.
For long term result edit the contents, zip the database, and replace
the EPSG.zip in that jar.

Which means 127.0.0.1 is not associated to the "localhost" name on
your machine. I think some Windows install do not have that association,
and that you can create it by hand editing the hosts file. A quick 
Google search on the topic turns out a number of results:

If the original image is RGB (instead of RGBA) it is.
There is currently no way to specify a transparent output color for
single images, only the mosaic plugin has this ability.
Which also means a workaround is to create a mosaic with a single image
in it.

Correct. Want to help out? The code that draws graphics strokes is in 
GeoTools, and sure needs improvements. Look here:

http://svn.osgeo.org/geotools/branches/2.6.x/modules/library/render/src/main/java/org/geotools/renderer/lite/StyledShapePainter.java

in particular the "drawWithGraphicsStroke" method

This kind of error most often happens if a layer does not have a default 
style anymore. Check that layer and see if the configuration is complete.

Nope, there is a jira issue but we don't have a patch right now:
http://jira.codehaus.org/browse/GEOS-3592

Gabriel provided a patch in a related issue but that is probably going
to slow down installations that do have a native JAI around.

The issue is basically making sure that not only the native acceleration
is enabled, but also that it is actually available, and the doubt is 
where to do that, in the GS map producer or in the GT ImageWorker?
This is probably something that Simone has to answer to (or Daniele).

There is no easy way. I think it might be possible using the application
schema module but you'd have to resort to do quite a bit of manual XML 
editing and I don't have a firm grasp of what parts of the WFS protocol
do actually work with application schema (at some point 
DescribeFeatureType was not working, not sure it has been fixed in the 
meantime)

Your Oracle is probabloy fighting against connection pooling and killing
connections that have been idle for some time.
You can have the connection pool check the connection is still good 
before usage by enabling the "validate connection". It will come with
a little overhead but ensure a connection returned by the pool to
the rendering code is a valid one
