<p>Hi all,</p>
<p>I have updated the second quick start tutorial on SYMBOLS and
symbolizing data. A draft page is available at: <a
href="https://geographika.github.io/tutorial/quickstart/symbolizing.html">https://geographika.github.io/tutorial/quickstart/symbolizing.html</a></p>
<p>I ran through this with around 6 people, and a few questions came
up. If anyone can provide details that would be very helpful. Also
comments/improvements on the tutorials are very welcome. <br>
</p>
<p>1. Are there any performance or other benefits of VECTOR symbols
over IMAGE/SVG? (Although I think SVG is currently not available
in ms4w - <a href="http://www.ms4w.com/trac/ticket/3">http://www.ms4w.com/trac/ticket/3</a>
). The manual entering of coordinate details seems pretty
difficult compared to using/making SVGs. <br>
</p>
<p>2. At the top of the <a
href="http://mapserver.org/mapfile/style.html#style">http://mapserver.org/mapfile/style.html#style</a>
page there is the sentence "The final intent is to have named
styles (Not yet supported) that will be re-usable through the
mapfile." I presume this means there was a plan to use STYLES
similar to a SYMBOLSET? Are there still any plans to do this?</p>
<p>3. I was looking to create circle symbols of different sizes
based on an attribute, using one of the datasets from Natural
Earth. The cities with large populations has a smaller "RANK_MAX"
- so the size needs to be inverse to an attribute. There does not
appear to be any easy way to do this without modifying the data.
You can set the size using an attribute e.g. "SIZE [MYHEIGHT]" but
is there a good reason why a MapServer expression couldn't be used
here? I can add as a feature request to GitHub if it could be a
nice addition. <br>
</p>
<p>A final question - should I post these emails to the dev or users
MapServers lists?<br>
</p>
<p>Regards,</p>
<p>Seth<br>
