I guess your problem is not changing the size of the symbolizer based on the scale then. > I will look into CSS to see if my VERY LARGE SLDs could be made more > "readable" or at least shorter. That will definitely make for much more compact specifications, easier to read, and quicker to write. Though I guess you may want to use SLDs for a few months to come, at least until the SLD workshop at FOSS4G :-p http://2011.foss4g.org/sessions/practical-use-geoserver-sld-wms > One SLD file with 13 scaleintervals each having 3 - 8 areaintervals means > that I have to write the name of the SVG-file, Stroke colours etc many > times. > My guestion: > It would be very nice to be able to start the SLD with PARAMETERS > (SVG_file_1, SVG_file_2 ...) ie. > SVG_file_1 = xyz_1.svg > SVG_file_2 = xyz_2.svg > etc. > and then I only have to change xyz_1.svg, xyz_2.svg etc. to my SVG > filenamnes right in the beginning of the SLD file. > I hope you understand my problem. Not really no. Seeing the SLD in question would help. > I looked at the "env" variable but I couldn´t figure out if it could be > used. It is used to pass into the SLD values coming from the WMS request itself. It is documented here: http://docs.geoserver.org/stable/en/user/styling/sld-extensions/substitution.html If you want to change the name of a SVG on a per request basis you can do so by adding &env=svg1:symbol1 and then have the following in the SLD (using the dynamic symbolizers features, another GeoServer extension): <OnlineResource xlink:type="simple" xlink:href="${env('svg1')}.svg"/> that is calling the env function with 'svg1' as the key. You can also provide a default value to have a valid SLD even when the parameter is not provided in the request: <OnlineResource xlink:type="simple" xlink:href="${env('svg1', 'defaultSymbol')}.svg"/> In this case if you don't specify the value of svg1 in the request you'll get defaultSymbol.svg as the default svg file Ah, though I never tried, as far as I know most of the above can be done in CSS as well, so you can have the style be compact and parametric at the same time.
