 <div class="block">A parameterized mathematical operation that converts coordinates to another CRS without any change of
  <a href="../datum/AbstractDatum.html" title="class in org.apache.sis.referencing.datum">datum</a>.
  The best-known example of a coordinate conversion is a map projection.
  The parameters describing coordinate conversions are defined rather than empirically derived.

  <p>This coordinate operation contains an <a href="DefaultOperationMethod.html" title="class in org.apache.sis.referencing.operation">operation method</a>, usually
  with associated <a href="../../parameter/DefaultParameterValueGroup.html" title="class in org.apache.sis.parameter">parameter values</a>.
  In the SIS implementation, the parameter values can be either inferred from the
  <a href="transform/AbstractMathTransform.html" title="class in org.apache.sis.referencing.operation.transform">math transform</a>
  or explicitly provided at construction time in a <cite>defining conversion</cite> (see below).</p>

  <div class="section">Defining conversions</div>
  <code>OperationMethod</code> instances are generally created for a pair of existing <a href="AbstractCoordinateOperation.html#getSourceCRS()">source</a>
  and <a href="AbstractCoordinateOperation.html#getTargetCRS()">target CRS</a>. But <code>Conversion</code> instances without those information may exist
  temporarily while creating a <a href="../crs/DefaultDerivedCRS.html" title="class in org.apache.sis.referencing.crs">derived</a> or
  <a href="../crs/DefaultProjectedCRS.html" title="class in org.apache.sis.referencing.crs">projected CRS</a>.
  Those <cite>defining conversions</cite> have no source and target CRS since those elements are provided by the
  derived or projected CRS themselves. This class provides a <a href="#%3Cinit%3E(java.util.Map,org.opengis.referencing.operation.OperationMethod,org.opengis.referencing.operation.MathTransform,org.opengis.parameter.ParameterValueGroup)">constructor</a> for such defining conversions.

  <p>After the source and target CRS become known, we can invoke the <a href="#specialize(java.lang.Class,org.opengis.referencing.crs.CoordinateReferenceSystem,org.opengis.referencing.crs.CoordinateReferenceSystem,org.opengis.referencing.operation.MathTransformFactory)"><code>specialize(…)</code></a> method for
  <a href="transform/DefaultMathTransformFactory.html#createParameterizedTransform(org.opengis.parameter.ParameterValueGroup)">creating a math transform from the parameters</a>,
  instantiate a new <code>Conversion</code> of a more specific type
  (<a href="http://www.geoapi.org/3.0/javadoc/org/opengis/referencing/operation/ConicProjection.html?is-external=true" title="class or interface in org.opengis.referencing.operation" class="externalLink"><code>ConicProjection</code></a>,
   <a href="http://www.geoapi.org/3.0/javadoc/org/opengis/referencing/operation/CylindricalProjection.html?is-external=true" title="class or interface in org.opengis.referencing.operation" class="externalLink"><code>CylindricalProjection</code></a> or
   <a href="http://www.geoapi.org/3.0/javadoc/org/opengis/referencing/operation/PlanarProjection.html?is-external=true" title="class or interface in org.opengis.referencing.operation" class="externalLink"><code>PlanarProjection</code></a>) if possible,
  and assign the source and target CRS to it.</p>

  <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. This means that unless otherwise noted in the javadoc,
  <code>Conversion</code> instances created using only SIS factories and static constants can be shared
  by many objects and passed between threads without synchronization.</div>

  <div class="section">Relationship between datum</div>
  By definition, coordinate <b>conversions</b> do not change the datum. Consequently the given <code>sourceCRS</code>
  and <code>targetCRS</code> should use the same datum. If the datum is not the same, then the coordinate operation
  should probably be a <a href="DefaultTransformation.html" title="class in org.apache.sis.referencing.operation">transformation</a> instead.
  However Apache SIS does not enforce that condition, but we encourage users to follow it.
  The reason why SIS is tolerant is because some gray areas may exist about whether an operation
  should be considered as a conversion or a transformation.

  <div class="note"><b>Example:</b>
  converting time instants from a <a href="../crs/DefaultTemporalCRS.html" title="class in org.apache.sis.referencing.crs">temporal CRS</a> using
  the <cite>January 1st, 1950</cite> epoch to another temporal CRS using the <cite>January 1st, 1970</cite> epoch
  is a datum change, since the epoch is part of <a href="../datum/DefaultTemporalDatum.html" title="class in org.apache.sis.referencing.datum">temporal datum</a> definition. However such operation does not have all the accuracy issues of transformations
  between geodetic datum (empirically determined, over-determined systems, stochastic nature of the parameters).
  Consequently some users may consider sufficient to represent temporal epoch changes as conversions instead
  than transformations.</div>

  Note that while Apache SIS accepts to construct <code>DefaultConversion</code> instances
  with different source and target datum, it does not accept to use such instances for
  <a href="../crs/DefaultDerivedCRS.html" title="class in org.apache.sis.referencing.crs">derived CRS</a> construction.</div>
