Hi Geoserver User list
I have a layer where I want certain rules to be rendered higher in the z-order,
using the vendor option 'sortBy', as described
here<https://docs.geoserver.org/latest/en/user/styling/sld/extensions/z-order/index.html>.
However the field I wish to sort on is text, not numeric.
I thought I could do this using the Recode function, as follows:
<sld:VendorOption name="sortBy">
<ogc:Function name="Recode">
<ogc:PropertyName>OPERATING_STATUS</ogc:PropertyName>
<ogc:Literal>mineral deposit</ogc:Literal>
<ogc:Literal>50</ogc:Literal>
<ogc:Literal>historic mine</ogc:Literal>
<ogc:Literal>60</ogc:Literal>
<ogc:Literal>closed</ogc:Literal>
<ogc:Literal>70</ogc:Literal>
<ogc:Literal>under development</ogc:Literal>
<ogc:Literal>80</ogc:Literal>
<ogc:Literal>feasibility</ogc:Literal>
<ogc:Literal>80</ogc:Literal>
<ogc:Literal>care and maintenance</ogc:Literal>
<ogc:Literal>90</ogc:Literal>
<ogc:Literal>operating mine</ogc:Literal>
<ogc:Literal>100</ogc:Literal>
</ogc:Function>
</sld:VendorOption>
But this seems to do nothing. Is there a way to sort a text field according to
a preset numerical ordering?
Thanks
Michael
