MarkIndex was indeed not implemented until a few months ago. It is right
now implemented only for TTF fonts, in order to support
QGIS font based symbols export (I believe you'll find it in 2.10.x, but I'm
not 100% sure, going by memory here).

The specification does not really say which symbol sets should support
markIndex, or does it? All I can find is:

"The alternative to a WellKnownName is an external mark format. The
MarkIndex
allows an individual mark in a mark archive to be selected. An example
format for an
external mark achive would be a TrueType font file, with MarkIndex being
used to
select an individual glyph from that file."

Cheers
Andrea

Right! seems the link to my old sample data is missing. I will try to 
find them back and tell you.


Yep, would be interesting to test with the latest GeoServer.

Especially I remember that I had some difficulties to use the MarkIndex 
capability of SE with deegree3 (see discussion 
http://osgeo-org.1560.x6.nabble.com/SE-Styling-MarkIndex-glyph-index-td5022210.html). 
No idea how GeoServer does implement what the SE spec describes about 
this MarkIndex (at the time of writing the tutorial, I finally decided 
to remove the Markindex example from it).


Best regards,
Olivier.

The main missing point in GeoServer SE support is raster symbolizer,

Hopefully it's going to get better with the interest the user

Re: [OSGeo-Discuss] [OSGeo-Edu] Web cartography, SLD

2016-12-09 Thread Olivier Ertz 

Regie,
may be this tutorial on SLD/SE1.1 with deegree3 is useful (it has been 
built at the time of FOSSGIS 2013 in Switzerland):

http://mediamaps.ch/doku.php?id=ogo:sld_se_part1

Like GeoServer, deegree3 is a WMS/SLD OGC reference implementation, but 
in 2013, it was also compliant with Symbology Encoding 1.1 (SE) which is 
part of the replacement of the deprecated SLD 1.0. Moreover SE1.1 does 
offer few new capabilities, especially transformation functions 
(interpolate, recode, categorize).


Of course, GeoServer does offer interesting additional "vendor 
capabilities", but if you want portrayal interoperability, then you 
shall not use them. Nonetheless, these are often relevant capabilities 
which are currently taken into account in the current on-going redesign 
process at OGC, although it is quite a slow process, unfortunately.


If you are interested in this redesign, there is an article "/Redesign 
of OGC Symbology Encoding standard for sharing cartography/" which tries 
to summarize some of the major ideas to build a sustainable next 
generation SE standard (https://peerj.com/preprints/2415). Feel free to 
comment.


Hope this can help you.

Best regards,
Olivier.

What gives you that impression? if there is something missing feel free to

2016-12-01 Thread Regie Alam 
Hello Stefan,

   Thanks very much for pointing out those 2 tutorials and the GeoServer
SLD documention.

   I am actually looking for a "packaged" training and/or workshop that I
can attend (either in-class or online) where I can learn best-practices for
web cartography and using SLD.

   I'm actually surprised that not that many individuals and organizations
offer training services about SLD. Is SLD only used by the GeoServer
community? Why the lack of documentation? Are there other vector styling
technologies and techniques more commonly used?

Best Regards,
Regie
