</span>i tried but you can't set zoom levels/precision with wfs [1] and geojson [2].<br></blockquote><div><br><br></div><div>Yes - you must use BBOX= with WFS. You can get all the BBOX info you need by using globalmaptiles.py for your area of interest. You can get that script here: <a href="http://www.maptiler.org/google-maps-coordinates-tile-bounds-projection/">http://www.maptiler.org/google-maps-coordinates-tile-bounds-projection/</a><br> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

</span>interesting. i tried gdal2tiles but it creates raster not vector tiles.<br>
</blockquote></div><br></div><div class="gmail_extra"><br>Yes OGR2OGR is for vector to vector conversions. Spatial extent options can be passed in using the BBOXes obtained from the same script mentioned above.<br></div><div class="gmail_extra"><br></div></div>
