DDS Plugin for geoserver

[vash]

I have written a plug in that allows geoserver WMS to serve dds tiles. This avoids WorldWind clients to convert png tiles into dds.
I've used the "gov.nasa.worldwind.formats.dds.DDSConve rter" class from the WWJ sdk to perform the conversion.

ddsGeoserverPlugin-src.zip

plugin-dds-geoserver.jar

To use it just copy the plugin-dds-geoserver.jar and worldwind.jar from the WWJ sdk into the subdirectory "webapps\geoserver\WEB-INF\lib" of your geoserver installation and restart geoserver.

Hey, I still haven't tried it out but it sounds very interesting. Want to join us (GeoServer developers) on the gs-devel mailing list and maybe turn this plugin into a GeoServer community module?

Hi Andrea, i appreciates your interest. Thanks for the work you're doing on GeoServer which is a wonderful implementation of OGC standards. I will be glad to help you turning my plugin into a GeoServer community module.

You have nothing to configure. If it works properly the plugin add this output format to the WMS getCapabilities :

<Format>image/dds</Format>

So just make a WMS request requesting this output format. Ex :

http://localhost:8080/geoserver/wms?bbox=-127.61950064999999,23.7351786,-64.08177035,50.592523400000005&styles=&Format=image/dds&request=GetMap&version=1.1.1&layers=topp:states&width=800&height=317&srs=EPSG:4326

edit : I've just tested the plugin with the last 1.7.2 version and it doesn't work. Please use the 1.6.5 version of geoserver for the moment.

Hi All,

I have updated the DDS plugin against the latest geoserver SVN code and added a BIL format producer as well based on WCS code. I would welcome feedback and usage notes. I have tested in eclipse using a geoserver SVN build but not in a live environment. The extra dependency added is worldwind.jar which is used for dds production. Give it a whirl and let me know. It can be deployed in the usual copy .jar to geoserver/WEB-INF fashion.

The corresponding geoserver issue with .jar attached can be found here:
http://jira.codehaus.org/browse/GEOS-3586

Cheers,

Hi,

I am trying to use the dds/bil plugin for Geoserver but get some problems. When I choose the output format bil from the Layer preview panel from Geoserver administration, I get a binary file. But when I try to use the WMSBasicElevationModel to render the file from Geoserver, I get some problem due to the instruction "bg=-9999.0d" in the url...

If somebody can explain that and/or give me some infos about how to configure correctly Geoserver, it would be really nice !

Thanks
Thomas

PS : I am using Geoserver 2.0RC2 with a simple dem file using Geotiff format...

Hi,

After a lot of research, I copied the file WMSBasicElevationModel and commented the lines which are setting the bg parameter.
But after that, I get another problem : the server says : "Cannot fetch BIL float data, Wrong underlying data type".
So I used the debug mode and saw that ww used the application/bil32 format. So I forced it to ask for application/bil16 format.
Using this, I get some Elevation data, but the values are incredibles ! (-12 3567, 60 987...)
Moreover, I get this error : "getLayerExtremeElevations: GRAVE: Error parsing value".

I don't know what to try anymore...
If somebody gets an idea, it would be great...
Thanks in advance,
Thomas

Hey 1st user of my plugin,

In addition to the format type you also need byteorder for it to work properly i.e. LittleEndian and BigEndian, the raw binary data is subject to different interpretation with the different byte orders. I have just been shown how to add a Format operator to convert int to float etc. so that you don't have to worry about the native data type, may be I can add stuff to fix the byte order as well.

The plugin is also now an official geoserver plugin.
