[Geoserver-devel] [Geoserver-users] imagemosaic and filtering

Hi Simone:

After I read your message I attempted to add the filtering
capabilities to the imagemosaic module. I worked using geoserver
2.0-RC1 and geotools trunk. The filtering seems to work--I had to
modify the imagemosaic plugin a little, as well as GetMapResponse.java
in geoserver's WMS module.
Here is a sample request:

http://localhost:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&layers=sf:WorldCountries,nurc:mosaic&styles=&bbox=6.34617490847439,36.4917718219401,20.8296831527815,46.5907669751351&width=512&height=357&srs=EPSG:4326&format=image/png&cql_filter=INCLUDE;location='global_mosaic_9.png'+OR+location='global_mosaic_1.png'

The result from the request can be seen here:

Should I make a JIRA to see if the code can be included in svn?

Thanks,
Alex

Ciao Alex,
actually there is no such a capability in the currecnt version of the
imagemosaic, but it would be fairly easy to add it since internally
there is an index visitor that visit each feature in the JTS in memory
index, we could simply add the filter evaluation there.

Simone.

Hi:

Is it possible to filter an imagemosaic-configured coverage (or
imagemosaic-jdbc for that matter) with a filter or a cql_filter?
Similar to:
....&cql_filter=location='global_mosaic_9.png'

The reason I am asking is that I have overlapping images in my mosaic,
and would like to filter out images that are from say a single date.
This is the request returning the full contents of the mosaic:

http://www.smoke-fire.us:8080/geoserver/wms?bbox=-4995663.0,-1749623.0,2009396.0,4386310.0&styles=&Format=image/png&request=GetMap&version=1.1.1&layers=topp:tiles&width=800&height=657&srs=EPSG:41110

Thanks,
Alex

Ciao Alex,
can you open up a Jira with your patch so that I can play with it?
