Following up with Ian suggestion,
the original filter contains several extra operations... I cannot try it of
course, don't have the data,
but what about something like this:
<ogc:Filter>
<ogc:And>
<ogc:PropertyIsGreaterThan>
<ogc:PropertyName>median_tot_hhd_inc_weekly</ogc:PropertyName>
<ogc:Literal>0.0</ogc:Literal>
</ogc:PropertyIsGreaterThan>
<ogc:PropertyIsGreaterThan>
<ogc:PropertyName>median_mortgage_repay_monthly</ogc:PropertyName>
<ogc:Literal>0.0</ogc:Literal>
</ogc:PropertyIsGreaterThan>
<ogc:PropertyIsBetween>
<ogc:Div>
<ogc:PropertyName>median_mortgage_repay_monthly</ogc:PropertyName>
<ogc:Mul>
<ogc:PropertyName>median_tot_hhd_inc_weekly</ogc:PropertyName>
<ogc:Literal>4.33333333</ogc:Literal>
</ogc:Mul>
</ogc:Div>
<ogc:LowerBoundary>
<ogc:Literal>0.3</ogc:Literal>
</ogc:LowerBoundary>
<ogc:UpperBoundary>
<ogc:Literal>0.8</ogc:Literal>
</ogc:UpperBoundary>
</ogc:PropertyIsBetween>
</ogc:And>
</ogc:Filter>
Observations:
- The filters are in a different namespace than the SLD elements, given
your prefix declaration in the top element, they should all be prefixed by
"ogc:"
- A single and can have as many predicates as you like, they are going
to be evaluated in turn with short circuit evaluation
- No need to multiply by 100, just use 0.3 and 0.8 instead of 30 and 80
- PropertyIsBetween seems indeed more concise and clear, avoids
repeating the subject of the comparison twice
As said, could test it, but hope it's useful nevertheless
Cheers
Andrea
