[Geoserver-users] Colormap on Float64 raster

GeoServer GeoServer User
1

Hello,

I'm trying to user GeoServer to publish rasters stored in Float64 type.
For the data to be visually understandable, I put in place an SLD file
(using uDig).

Rendering these rasters with uDig and even QGis works well, but when it
comes to rendering with geoserver, all i get is an empty image.

Here are the screenshots :
Rendering in QGIS directly from file and created SLD file
<http://osgeo-org.1560.x6.nabble.com/file/n5195778/from-file-with-sld.png&gt;
Result of getmap request : all white
<http://osgeo-org.1560.x6.nabble.com/file/n5195778/with-wms.png&gt;

Just to be sure, I tried using WCS to get the raw data and everything seems
fine
<http://osgeo-org.1560.x6.nabble.com/file/n5195778/with-wcs.png&gt;

Here is the SLD used :

Dear Cyril,
I have opened a bug report for this:

https://osgeo-org.atlassian.net/browse/GEOS-7048

We will look into this in the upcoming weeks during our community time slots.

Dear Simone,

On my side I solved the problem by using the ImageMosaic plugin which does
not seem to be affected by this problem.

Hope this help,

Cyril

Hi,
I believe I’ve found a fix for this problem (https://osgeo-org.atlassian.net/browse/GEOS-7048) but
I need to write a test, and the features of this tiff files are … unique.
Can I use that file (a reduced resolution version of it) to write an automated test back in GeoTools
(which means, the file will become part of the GeoTools source code, and redistributed along with it).

Cheers
Andrea

Andrea,

Now that you mentionned it, I did have a bug with the Y axis that I fixed
later.
But I already moved to the ImageMosaic plugin at that time so I did not
retry with the default driver.
You can off course use the given test files. FYI I used gdal + python to
generate this raster, and mixed up some parameters in the geotransform until
I realized it.

Cyril
