Case scenario:

I need to create symbology that takes fill, stroke and stroke width with information from the database. Problem arises with custom defined symbols like the one on the image. There are lot of them.

One of the solution that came to my mind was to create font and style that font. But that approach is not possible because I can only set fill to the font, not stroke and stroke width. Next idea was to use SVG and somehow try to dynamically set fill, stroke and stroke width. But I had no success. I tried the approach at How to create svg symbols that have modifiable fill color, stroke color and stroke width? but with no success.

Is there a way to do this using GeoServer?

  • You should be able to do this with SLD using Filters. If you can share the data (or a sample of the data), perhaps we could come up with an example.

  • I now it can be done with Filers but I it is almost impossible to create so many different rules. I would need to create all possible combinations for fill, stroke, stroke-width, font type, etc. etc. Unfortunately I do not have access to this data any more but I have solved it by creating a web service that dynamically creates SVG based on URL parameters. URL is generated from SLD dinamicaly from database. Good thing is that Geoserver has very good caching of symbols and there is very little overhead of this approach.

  • Maybe you could add that as an answer and close this out. Not sure how else it could be answered / closed.

Eventually I have solved this problem by creating a web service that dynamically creates SVG based on URL parameters. URL is generated from SLD dynamically from database. Good thing is that Geoserver has very good caching of symbols and there is very little overhead of this approach. Of course, web service also caches symbols local so that it doesn’t have to recreate already requested symbols again and again.
