		<h1>About GeoNetwork opensource</h1>
		<p>This site is powered by <a href="http://geonetwork.sourceforge.net" target="_blank">GeoNetwork opensource 2.0.2</a>.
		</p>
		<p>
			<strong>GeoNetwork opensource</strong> is a standardized and decentralized spatial information management environment, designed to enable access to geo-referenced databases, cartographic products and related metadata from a variety of sources, enhancing the spatial information exchange and sharing between organizations and their audience, using the capacities of the internet. This approach of geographic information management aims at facilitating a wide community of spatial information users to have easy and timely access to available spatial data and to existing thematic maps that might support informed decision making.

			<span lang="EN-US">Maps, including those derived from satellite imagery,</span> are effective communicational tools and play an important role in the work of various<span lang="EN-US"> types of users:</span>
		</p>
		<ul type="disc" style="margin-top: 0cm;">
			<li>
				Decision Makers: e.g. Sustainable development planners and humanitarian and emergency managers in need of quick, reliable and up to date user-friendly <span lang="EN-US">cartographic </span>products as a basis for<span lang="EN-US"> action</span><span lang="EN-US"> </span><span lang="EN-US">and better plan and monitor their activities.</span>
			</li>
			<li>
				GIS Experts in need of exchanging consistent and updated geographical data.
			</li>
			<li>
				Spatial Analysts in need of multidisciplinary data to perform preliminary geographical analysis and reliable forecasts to better set up appropriate interventions in vulnerable areas.
			</li>
		</ul>
		<p>
			<span lang="EN-US">The main goal of the <b>GeoNetwork opensource </b> software is to improve the accessibility of a wide variety of data, together with the associated information, at different scale and from multidisciplinary sources, organized and documented in a standard and consistent way. </span>
		</p>
		<p>
			<span lang="EN-US">The challenge is to enhance the data exchange and sharing between the organizations to avoid duplication, increase the cooperation and coordination of efforts in collecting data and make them available to benefit everybody, saving resources and at the same time preserving data and information ownership.</span>

The three agencies make extensive use of computer-based data visualization tools, known as Geographic Information System (GIS) and Remote Sensing (RS) software, mostly to create maps that combine various layers of information. <b>GeoNetwork opensource </b> provides them with the capacity to access a wide selection of maps and other spatial information stored in different databases around the world through a single entry point.</span>

			<b><span lang="EN-US">GeoNetwork opensource </span></b><span lang="EN-US"> has been developed to connect spatial information communities and their data </span>using <span lang="EN-US">a modern architecture, which is at the same time powerful and low cost, based on </span>the principles of Free and Open Source Software (FOSS) and International and Open Standards for services and protocols<span lang="EN-US"> (a.o. from <a href="http://www.isotc211.org" target="_blank">ISO/TC211</a> and <a href="http://www.opengeospatial.org" target="_blank">OGC</a>).</span>
