Ciao Simone,
I tried with ChannelSelection in SLD before, but I think I wasnt using
it with right combination of mosaic parameters.
At the end I solved the problem by setting these parameters:
Mosaic parameters:
BackgroundValues :255
InputTransparentColor: FFFFFF
OutputTransparentColor: FFFFFF
HandleFootprint: false
SLD:
<RasterSymbolizer>
<ChannelSelection>
<GrayChannel>
<SourceChannelName>1</SourceChannelName>
</GrayChannel>
</ChannelSelection>
<ColorMap type="values" extended="false">
<ColorMapEntry color="#ff6600" quantity="0" label="0"
opacity="1" />
<ColorMapEntry color="#ffffff" quantity="1" label="1"
opacity="0" />
</ColorMap>
</RasterSymbolizer>
(+ adding transparent=true to request off course )
Grazie Daniele&Simone :)
Regards,
Ivan
