<b>件名:</b> [OSM-dev] Introducing PGMapCSS 0.1.0<br>
</div>
<br>
<pre class="k9mail">Hi!<br /><br />I spent the last week hacking together a new project. It's an<br />implementation of MapCSS for Mapnik, called PGMapCSS. Yet another? No. In<br />contrast to other CSS implementations for Mapnik, PGMapCSS runs in the<br />database and evaluates the CSS rules for every object. This makes more<br />advanced checks and calculations possible; even geometric modifications<br />are possible (though not implemented yet).<br /><br />Mapnik just needs to read those values and render them.<br /><br />And this is currently the big limitation of this method: Mapnik can't use<br />expressions for most of it's Symbolizer options (not even colors or<br />rotation angles).<br />(This is something that already annoyed me when I first started to use<br />Mapnik in 2008 - see Mapnik issue #828).<br /><br />So, PGMapCSS is currently only a technological experiment. Though for a<br />technological experiment it's already quite full-featured.<br /><br />And here is the
precious link to the source and documentation:<br /><a href="https://github.com/plepe/pgmapcss">https://github.com/plepe/pgmapcss</a><br /><br />What you need:<br />* PostgreSQL + PostGIS<br />* osm2pgsql<br />* Some way to render a mapnik file, e.g. mod_tile + renderd<br /><br />Check out the source, play with it, fork it, contribute back. Tell me what<br />you think of it. There might still be a lot of bugs.<br /><br />greetings,<br />Stephan<br />-- <br />Seid unbequem, seid Sand, nicht Öl im Getriebe der Welt! - Günther Eich<br />,<hr />.<br />| Stephan Bösch-Plepelits, |<br />| Technische Universität Wien - Studien Informatik & Raumplanung |<br />| Projects: |<br />| > <a href="http://openstreetbrowser.org">openstreetbrowser.org</a> > <a href="http://couchsurfing.org">couchsurfing.org</a> > <a href="http://tubasis.at">tubasis.at</a> > <a
