By the way, the SLD specifications uses the terme "FeatureTypeStyle" : I think it's a good candidate :)<br><br>See <a href="http://docs.geoserver.org/stable/en/user/styling/sld-cookbook/lines.html">http://docs.geoserver.org/stable/en/user/styling/sld-cookbook/lines.html</a><br>

Thanks Martin for your explanation !<br>I know understand why and how activating "symbol levels" has an effect of the rendering of my linestrings :)<br><br>As you have seen, I am no native english speaker, so I am not able to help find the proper vocabulary.

<br>We need to look at Mapserver, OpenLayers, GeoServers, SLD cookbook to find which terms they use, IMHO.<br><br>Kimaidou<br><br><div class="gmail_quote">2011/2/17 Martin Dobias <span dir="ltr"><<a href="http://wonder.sk" target="_blank">wonder.sk</a>@<a href="http://gmail.com" target="_blank">gmail.com</a>></span><div>

</div>Frankly, with the introduction of symbology-ng I have created some<br>
mess in the terminology and I am not sure how to get out of this.<br>
Where are the problems:<br>
- "style" - before the style referred to Layer style (i.e. renderer,<br>
labeling). symbology-ng uses this term for a collection of symbols<br>
(and other visual items)<br>
- "color ramp" - a convenient source of colors for symbology-ng.<br>
Shouldn't that be called a "colormap" since it could be either a color<br>
gradient, colors from a palette or just a bunch of random colors?<br>
- "layer" - there are map layers and there are symbol layers. I think<br>
that generally speaking, a layer always means a map layer.<br>
- "categorized" / "graduated" renderer - I remember Carson raising the<br>
discussion that these terms are not very clear<br>
<br>
An insight from a english native speaker and preferably a user of<br>
several GIS would be valuable. It would be good to disambiguate the<br>
terms.<br>

</div>Personally I do not like the term substyle order.<br>

</div>No, it is more complex. Normally when a renderer renders a map layer,<br>
for each feature it renders symbol layers one by one and proceeds to<br>
another feature. By enabling symbol levels you tell the renderer that<br>
it should first render first symbol layer of each feature and then<br>
render second symbol layer of each feature. The numbers in the symbol<br>
level table tell in what pass a symbol layer will be drawn (smaller<br>
number = drawing earlier).<br>
<br>
This probably needs a better introduction in a blog post or<br>
documentation with examples.<br>
