be able build it as you would any other branch – using cmake. You need protobuf and protobuf-c installed to be able to compile things though.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Configuring MVT output is really quite similar to configuring WFS or WMS output. The MVT renderer relies on the WFS/WMS/OWS/GML metadata items to define what
fields should be output and what they should be named. In my demo <a href="https://github.com/sdlime/mapserver/tree/vector-tiles">
https://github.com/sdlime/mapserver/tree/vector-tiles</a> the MVT related configuration is pretty much just the gml_* metadata items associated with each layer. I’m mapping shapefile fields to standard names in the MVT output for consistency – so every feature
has a name and a unique id. The id is referenced in the MVT specs (<a href="https://github.com/mapbox/vector-tile-spec">https://github.com/mapbox/vector-tile-spec</a>) and must be unique within a layer.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">From there it’s just a matter of setting the image type. In the case of the demo I do that remotely – as a parameter in the service URL but I could just as easily
just set IMAGETYPE ‘mvt’ in the mapfile.<o:p></o:p></span></p>

<p class="MsoNormal">I'm very interested in MapBox Vector Tiles, because I'd like to do client-side rendering. I found a branch in several github clones (tbonfort,sdlime) but it's not clear to me if/how I could try them out.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">My setup is perhaps a little unusual: I run a small cluster of Java-based web servers, each of which links to the MapServer shared library. I therefore do not use WMS or MapCache.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">How would I configure a .map file to generate a .mvt file? Is this even possible? In Steve's mvt-demo, I see a parameter '<span style="font-size:9.0pt;font-family:Consolas;color:#032F62;background:white">map.imagetype=mvt</span>' hidden
in a JSON file, but nothing in the .map file seems to indicate that a .mvt should be created.<o:p></o:p></p>
