GeoServer Geotiff error

[chow kyo]

I use geoserver published a geotiff file, install bil plugin, but the client sends a request to get the. bil file only get the following code, what is the reason? Is the type of geotiff error?

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE ServiceExceptionReport SYSTEM "http://192.168.0.102:8888/geoserver/schemas/wms/1.1.1/WMS_exception_1_1_1.dtd">

  <ServiceException>
      BGCOLOR -9999.0 incorrectly specified (0xRRGGBB format expected)
  </ServiceException>
</ServiceExceptionReport>

That's an error due to a mismatch between how WorldWind expects a WMS to behave and how Geoserver does behave. Here is a hack that fixes it. I will try to modify the plugin to allow -9999.0 as a possible bgcolor.

Hi,

i get the same error mentioned above. But I don't see how the *hack* is solving it.
It seems to me like a conflict of geoserver expecting a hex value and world wind expecting a number. Either one results in an error.

I'm using Geoserver 2.2beta with the the dds/bil extenstion (http://docs.geoserver.org/stable/en/...dds/index.html) and World Wind SDK 1.3

Other solutions?

Cheers,
Kristina

While it might impose some extra work, you might consider using MapServer to dish up your GeoTIFF as BIL. It happily handles the -9999 value for background, can serve bil in multiple formats (including the 16 bit signed that WW demands). I use it (MapServer) to serve worldwide GMTED and ASTER that are stored as compressed GeoTIFF files.

Are there any updates concerning that issue? I'm VERY unhappy with mapserver (no GUI sucks) and would like to use geoserver again...

Xander, I've been trying to get mapserver to serve up .bils. I don't seem to be able to get it to work. I've got the GMTED2010 geotiffs on my server. The .bil files that I get on the client end are very strange. All of the low bytes have a value, and the high bytes are all zero. It seems to be coming from the mapserver like that. I can pass the URL to the mapserver, and that's what is downloaded. Did you have to do anything special to get MapServer to serve up Int16 .bils?

I'll be giving gmted2010 a look with my mapserver setup in about a week. I've been looking for more elevation examples to test against.

Hi Randy, I'm using MS4W, latest version, straight out of the box. The gdal in there says it supports Ehdr, so it should be able to serve .bils. I would also like to be able to serve DTED 0, 1 and 2, NED, CTED, and GTOPO30, but first things first.

Just to follow up, I took the Crater Lake sample tiff file that comes with the SDK, pointed a map server layer at it, and it worked perfectly. Elevation looked exactly as expected. I'm not sure what's different about the .TIFs for the GMTED2010 data. I also dropped one of those TIFs into the data directory right along side the crater lake file. Changed the importelevation sample java file to point to the GMTED geotif, and it failed to open the file when I tried to run it. I guess I'll spend some time on the USGS EarthExplorer site trying to figure out what's different about their geotifs.
