Using an external SLD file to style a layer
| Code Block | ||
|---|---|---|
| ||
<layer id="contours01" label="Contours 1m" layer="GIS.CONTOURS_01M" style="sld\contours.sld"/> |
...
Alternatively, when referring to an external SLD file it can also be specified in the style itself, rather than the layer, so the layer can reference one of the inline styles, and the style then points to the external SLD file, e.g.
| Code Block | ||
|---|---|---|
| ||
<styles> <style id="contour">sld\contours.sld</style> </styles> |
This way if you use the same SLD file for multiple layers you can just reference a single inline style and have that style refer to the SLD file.
