<h1>The World Atlas sample</h1>
This second more advanced tutorial is based on <b>World Atlas</b>, yet another <b>monolithic self-contained database</b> containing anything required by a rich high quality Map.<br><br>
<b>World Atlas</b> is based on a mix of both <b>Raster</b> and <b>Vector Coverages</b>, all them freely available as open data:
<ol>
<li><b>Blue Marble Next Generation by NASA</b>: an high-quality mosaic of cloud-free, medium resolution images collected by <b>MODIS</b> satellites during year 2001.</li>
<li><b>ETOPO1</b> an accurate <b>Global Relief Model</b> created in 2008 by <b>NOAA</b> (<b>National Oceanic and Atmospheric Administration</b>).</li>
<li>Several <b>Vector Coverages</b> derived from <b>Natural Earth</b>, a public domain worldwide map dataset:<ul>
<li><b>Admin 0 - Countries</b>: international borders of 258 countries.</li>
<li><b>Populated Places</b>: city and town points.</li>
<li><b>Airports</b>: international airports.</li>
</ul></li>
</ol>
In order to build the <b>World Atlas sample</b> we'll use many advanced styling options and other interesting quirks supported by the <b>rendering engine</b> of <b>librasterlite2</b>.<br>
Above all it will be an interesting didactic opportunity to deepen even the smallest details of the overall architecture.
