Hello. I am receiving a series of geotiffs (radar images) once every few minutes. I am adding the updated images into GeoServer via the REST interface.
I want to present these images as a single layer in GeoServer, and I'm wondering how to select between using a layer group and an image mosaic. I've hit some roadblocks with both approaches, though overall I've had more success with image mosaics. My problem with image mosaics: In GeoServer 2.0.2, it doesn't seem like I'm able to update an image mosaic. (When I do a PUT for an existing mosaic, the shape files for the mosaic are not updated.) So, I'm removing & re-creating the mosaic every time I get a new image, and I wonder how well this approach scales. Does re-creating the mosaic become more expensive as we add more images to it? My problem with layer groups: I have not been able to figure out how to specify transparency in a layer group of plain geotiffs. Using an image mosaic, I can PUT XML like http://pastie.org/1871543 to set the transparency color. I haven't had any success doing this using either a plain geotiff or a layer group. I'd really appreciate any insights on: * Selecting whether I ought to be solving this problem with layer groups or image mosaics. * Helping me resolve one or both of the issues I mentioned above. Thank you very much! alex ------------------------------------------------------------------------------ WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.
