Can I apply SLD filters to raster grids where the PropertyName is the band?
How can I compare 2 bands against each other?
Do I have to transform the raster to a feature?
Example
<Rule>
<And>
<PropertyIsLessThan>
<PropertyName>band1</PropertyName>
<Literal>1000</Literal>
</PropertyIsLessThan>
<PropertyIsGreaterThan>
<PropertyName>band2</PropertyName>
<PropertyName>band3</PropertyName>
</ PropertyIsGreaterThan >
<And>
</Rule>
<RasterSymbolizer>
//make it black
</RasterSymbolizer>
Thanks
