There was a good discussion on the osgeo list about setting up a wiki with SLD examples.
Personally I would love to see a quick catalog with the following items:
- visual (ie show what the result looks like)
- snippet (highlight the xml fragment that makes the example special)
- link (to the complete sld file)
It would be important to have the table of contents contain a thumbnail of each style.
I think I would find it easier to break up the subject by domain (ie what you are trying to renderer) rather than by simple/intermeditate/advanced). If you like you can organize each section along the lines of complexity; but the top level breakdown should be by domain.
You will often find that SLD examples are cumulative; the advanced examples are actually a small refinement of a previous simple example - as such you may find the subject matter naturally is organized into a progression from simple to advanced material.
Finally it would be very nice to have a final chapter covering extensions to SLD:
- GeoServer has some very handy extensions that would be nice to document (label handling and dynamic symbols for example)
- Symbology Encoding 1.1 is out and contains some additional concepts such as the use of ground units when supplying a buffer
It would also be handy in the catalog approach to document which applications the example works with (or which rendering engines if you are short on space).

I am writing new documentation for using SLD in GeoServer, and I’m
looking to create an SLD “cook book” where various styles will be placed
for easy reference. I am looking for suggestions of the types of styles
that would be good to have in this list. I was thinking of dividing the
list into “simple”, “intermediate”, and “advanced”, although I recognize
that that’s a bit arbitrary, and perhaps might be better if I used other
delimiters such as “point”, “line”, “polygon”, “raster”. Anyway, if you
have any suggestions, either on specific styles to highlight (you don’t
need to post SLD code here if you don’t want, just ideas) or in the
structure of this cook book, please let me know. (Think: What would
you have liked to have seen when you were learning about SLD?)
Thanks,
