I have spent the complete day creating a single SLD file and tuning it, and I am on the one hand really pleased with the actual result, but really frustrated how cumbersome it is to edit and test SLD's using Geoserver web-interface.

In theory it is really simple: edit the SLD, "submit" and I scroll my layer-preview and see instant change.

But then my labels need to be shifted down a little, so I return to the styles view, search for my SLD, search the relevant label in my SLD (that tiny edit screen --what is it: 20 lines? is not really helping), save, and it starts all over again.

How do you edit/manage your SLD's?

For instance my particular SLD I created today has 1300 something lines, to describe 24 cases of drawing a point-symbolizer with a label, and to me this seems like a simple case.

I also have a lot of repetition for each rule, because the only thing that changes between the cases is the image I use, and the position of the label.

Are there any tools that help in editing/previewing SLD's? Can you actually edit the file directly? (damn, I did not try that, I assumed not because Geoserver needs to be "aware" it changed?).

Things I just thought of:

  • try to just edit the file in place using my favorite text-editor to see if that works
  • I just noticed that each SLD has a unique URL, that would save me the navigation to the SLD

As other said, look in GeoServer 2.10 announcement for a better editor workflow.

As for the repetition, you can probably get rid of some by using the transformation functions, but mind, legend generation won't work anymore if you use them: http://docs.geoserver.org/stable/en/user/styling/sld/tipstricks/transformation-func.html

If instead you have more complex cases you can look into alternative styling languages such CSS, where the repetition can be eliminated by using rule cascading and nesting: http://docs.geoserver.org/latest/en/user/styling/css/tutorial.html

  • Awwwwesome: the new editor indeed looks very cool! But the css! WOW! So readable and compact and cascading and nesting!! Thanks :) :) <3 <3 <3 – nathanvda Nov 17 '16 at 12:19
