Hi Andrea,
No I am not doing any reprojection according to me.
I just had a closer look in my logs, and I just saw :

Is it normal that there are more than 2 minutes between the two logs ?
Regarding the error, not sure to understand why. If correctly understand the style definition :
<Rotation>
<ogc:Function name="toDegrees">
<ogc:Function name="atan2">
<ogc:PropertyName>Band2</ogc:PropertyName>
<ogc:PropertyName>Band1</ogc:PropertyName>
</ogc:Function>
</ogc:Function>
</Rotation>
It would mean than the output of atan2 cannot be an input of toDegrees ?
As far as I look into my input file, everything looks OK regarding the values (between -35 and 96 for U, and between -59 and 61 for V).

Hi PIerre,
question, are you reprojecting the raster data in the process?
In other words, is your request coordinate reference system different than the data one?
We have had reports that something is not working in those cases, and the output remains
blank, but haven't had time to look into it so far.
Cheers
Andrea

Hello,
I am not sure if I should use this mailing list to ask this question... correct me if I am wrong.
I have a geoTiff file containing U and V wind components in two separate bands and I am trying to display it on geoserver with arrows. I am on geoserver 2.6.2 and I am following the indications here : http://geoserver.geo-solutions.it/edu/fr/wps/rendering_tx.html
I have added the following style :

</ogc:Mul>
</ogc:Add>
</Priority>

</Rule>
</FeatureTypeStyle>
</UserStyle>
</NamedLayer>
</StyledLayerDescriptor>
And when I added my layer, I renamed the two bands in Band1 and Band2 and selected the style.
But when previewing the layer, it stays desperately blank without any error message.
Do you have any idea where I should look for to solve this issue ?
Thanks !
Pierre.
