<div class="block">Defines the origin from which longitude values are determined.
<div class="section">Creating new prime meridian instances</div>
New instances can be created either directly by specifying all information to a factory method (choices 3
and 4 below), or indirectly by specifying the identifier of an entry in a database (choices 1 and 2 below).
In particular, the <a href="http://www.epsg.org">EPSG</a> database provides definitions for many prime meridians,
and Apache SIS provides convenience shortcuts for some of them.
<p>Choice 1 in the following list is the easiest but most restrictive way to get a prime meridian.
The other choices provide more freedom. Each choice delegates its work to the subsequent items
(in the default configuration), so this list can been seen as <cite>top to bottom</cite> API.</p>
<ol>
<li>Create a <code>Prime­Meridian</code> from one of the static convenience shortcuts listed in
<a href="../CommonCRS.html#primeMeridian()"><code>Common­CRS​.prime­Meridian()</code></a>.</li>
<li>Create a <code>Prime­Meridian</code> from an identifier in a database by invoking
<a href="http://www.geoapi.org/3.0/javadoc/org/opengis/referencing/datum/DatumAuthorityFactory.html?is-external=true#createPrimeMeridian(java.lang.String)" title="class or interface in org.opengis.referencing.datum" class="externalLink"><code>Datum­Authority­Factory​.create­Prime­Meridian(String)</code></a>.</li>
<li>Create a <code>Prime­Meridian</code> by invoking the <code>Datum­Factory​.create­Prime­Meridian(…)</code> method
(implemented for example by <a href="../factory/GeodeticObjectFactory.html" title="class in org.apache.sis.referencing.factory"><code>Geodetic­Object­Factory</code></a>).</li>
<li>Create a <code>Default­Prime­Meridian</code> by invoking the
<a href="#%3Cinit%3E(java.util.Map,double,javax.measure.Unit)">constructor</a>.</li>
</ol>
<b>Example:</b> the following code gets the Greenwich prime meridian:
<blockquote><pre>PrimeMeridian pm = CommonCRS.WGS84.<b>primeMeridian</b>();</pre></blockquote>
<div class="section">Immutability and thread safety</div>
This class is immutable and thus thread-safe if the property <em>values</em> (not necessarily the map itself)
given to the constructor are also immutable. Unless otherwise noted in the javadoc, this condition holds if
all components were created using only SIS factories and static constants.</div>
