DDS Plugin for geoserver

[dbacar]

Forgot to thank, What_nick many thanks to you for the plugin...

I have been also testing the new plugin. DDS output works as expected, but I have the same weird elevation readings as anaxa_gore with the bil output.

I am inspecting the source code and could not see how you build up the BIL output image? Is this format natively supported by geoserver? I was expecting some image conversion routines but I could not see it. Can you give some hints?

Hi Dbacar,

I used the JAI Raw output option to directly dump the reprojected coverage (as raster data sources are called in geoserver) to the output stream. With the new code you can request any raster layer in geoserver as bil and it will end up as elevation in worldwind - no int16, float32 native data format restrictions.

The remaining trick is in the byte order. The received byte order is going to be the native one of the machine running geoserver. You will have to try both bigendian and littleendian to see what floats your boat.

Cheers,

Great Work on this plug-in!

I believe i have installed everything correctly, however i am getting some weird results. I basically have some shapefiles on geoserver that are displayed in WWJ.

However, when i specify dds as my image format, it comes our blurry and low resolution. It appears low resolution regardless of how much i zoom in or out. If I change the format to png and leave all settings the same, it looks fine.

DDS


PNG


Any ideas on what is causing this?

Im sure if WorldWind was an official sponsor of the Daytona 500 DDS would look much better ;p

Hi !

I am using the BilMapProducer to generate BIL files for WWJ through Geoserver.

The problem is that some tiles contain "no data values" on its borders. Normally these no data values should no appear (the data source does not contain these values).
I used the debugger and note that these values appeared after the WCSUtils.scale() in the BilMapProducer.java.

Does anyone know why the scale() operation insert (sometimes) errors in the bil file ?
And if so, somebody knows how to fix this problem ?

Thanks in advance for your help,
Thomas

I have the same problem.

After 3 or 4 days i didn't find any solution.

Anyone has an idea ?

My application included WWJ is unusable with this bug :

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:

hi what_nick
Hello, where you have the latest geoserver-dds plugin? For whichgeoserver's version?

[what_nick]

The latest plugin code should in geoserver maven, I will do the final push to get the plugin published as a standard extension soon.

Cheers,

Hi Guys,

I have been maintaining the bil/dds plugin for geoserver 2.1.x and trunk. I have added some docs. Please let me know if you would like to see and further additions to these basics.

I would also like some testers to try it out. I just know how it works, so I am not the best at picking out the details for the docs. The DDS module has been behaving a bit weird since I re-aligned it to the new Geoserver code so take it for a spin and let me know. The core mapresponse files are here. Review the code and let me know if any thing abnormal leaps out.

Cheers,

whatnick.

Hi What_nick,
For the last couple of days I have been using your old plugin code with geoserver 2.0.2 code base. I have upgraded the worldwind relatively a new version, and compiled the plugin from scratch with 2.0.2 version of geoserver.

So far it seems to be OK.
