This is my first attemp with QGIS. I'm using 2.0 version.</div><div style="font-style:normal;font-size:13.3333px;background-color:transparent;font-family:arial, helvetica, sans-serif;">My first goal is a proof of concept with a wms map and a vector map.</div>
<div style="font-style:normal;font-size:13.3333px;background-color:transparent;font-family:arial, helvetica, sans-serif;">I started with the wms service.
