[Geoserver-devel] Problems defining own coord system in 1.3.0 (Windows version)

Taylor_Stephen · February 5, 2006, 9:55pm

Dear GeoServer developers,

Thanks for your efforts in creating and maintaining GeoServer. I am trying to define my own coordinate system (CRS/SRS) in a Windows 2000 installation of version 1.3.0: I have tried to follow the steps on the FAQ page ‘Custom projection definition in GeoServer’, http://docs.codehaus.org/display/GEOSDOC/Custom+projection+definition+in+Geoserver, but nowhere within either the installed server files or the source tree could I find any file by the names ‘EPSG.sql’ or ‘gt2-epsg-h.jar’, or matching the pattern HSQL. In desperation I tried editing epsg.properties, but its contents (as warned somewhere in the documentation) seem to be entirely ignored by GeoServer.

Does GeoServer 1.3.0 still use gt2-epsg-h.jar, and if so where is it located?

Thanks very much for any help you can give.

Regards,

Stephen Taylor

Hello all, can you tell me the version of wfs and gml actually use by geoserver ?
Thanks.

WFS 1.0 and GML2, we have started development of WFS 1.1 filter support and various geoserver advocates are casting around for enough funding to do the rest. If you need to know more ping Chris Holmes.

For details you can visit this page:

Thanks for the interest,
Jody

Sorry, i forgot the subject…
I need to know the greater version of wfs and gml that is supported by Geoserver.
I need things from wfs 1.1 and GML 3.1.1 at least, and if possible 3.2…
I hope it is ok with Geoserver.

If not, is it planned, and when ?
Is it possible to think that i can work to upgrade Geoserver to support it ?
Thanks.
Tanguy.

Everything is okay on a branch my friend. If you want you can join the current development effort ...

If not, is it planned, and when ?

No it is not planned in terms of resources, yes it is planned in terms of technology, and yes it is planned in terms of a deadline The project is called "Community Schemas" near as I can tell... WFS 1.1 is a requirement of one of its later phases.

Is it possible to think that i can work to upgrade Geoserver to support it ?

Yes! Although you may have some fun with GML 3.2 ( a quick glance at the OGC portal shows me it is not out yet), so either you mean 3.1.1 or are an OGC member (and woudl need to ensure you can make the prototype schemas available for us to use, or do that part of the branch yourself until you get a chance to open source it later).

So the next question is what do you like doing? If you check out that hack page we have a couple things in the way of GML3.x support ....
- Filter 1.1 (just finished up the implementation, but we need to test the GTXML parser bindings)
- GML 3.1.1 - Filter 1.1 uses GML3 for its geometry literals - we have some GML3 parsing ready but more will be needed
- WFS 1.1 - limited to GetCapabilities, DescribeFatureType and GetFeatures

Right now the work is in four places:
- GeoAPI - (trunk) interfaces are being coddled into place (Jody)
- GeoTools - (branches/fm) implementations are being treated a bit more roughly (Justin)
- GeoServer - (branches/1.4.x) spring based architecture, so we don't go inane judling code, and for configuration ui

And the forth place? Is "branch hell", currently we are bringing to gether work from previous projects scattered evenly across the versioning system.

So the question comes down to what do you think would be fun to work on

Hi Stephen:

When I wrote the "Custom projection" wiki page, I did so while using
the WCS branch. It is apparent now that 1.3.0 and WCS use 2 different
ways to store/define projections:
1) 1.3.0 still uses the epsg.properties file in the gt2-epsg.jar archive
2) The WCS branch uses the HSQL database in the gt2-epsg-h.jar archive.

The archives in question are located in the WEB-INF/lib subdirectory
(for both branches).

The process you described of editing epsg.properties file should still
work, but then you will need to repackage the gt2-epsg.jar archive and
restart geoserver.

Watch the console output for any messages that the newly-defined
projection's WKT couldn't be parsed for any reason.

I will make sure to make additions to the wiki page.

Mr Ricaille, we talked in yesterdays IRC meeting about ways in which people can help out in the move towards WFS 1.1. If you jump on the developers list and talk to Justin we can get things going for you.
