| <div class="block">Defines the location and orientation of an ellipsoid that approximates the shape of the earth. |
| Geodetic datum are used together with ellipsoidal coordinate system, and also with Cartesian |
| coordinate system centered in the ellipsoid (or sphere). |
| |
| <div class="section">Bursa-Wolf parameters</div> |
| One or many <a href="BursaWolfParameters.html" title="class in org.apache.sis.referencing.datum"><code>BursaWolfParameters</code></a> can optionally be associated to each <code>DefaultGeodeticDatum</code> instance. |
| This association is not part of the ISO 19111 model, but still a common practice (especially in older standards). |
| Associating Bursa-Wolf parameters to geodetic datum is known as the <cite>early-binding</cite> approach. |
| A recommended alternative, discussed below, is the <cite>late-binding</cite> approach. |
| |
| <p>The Bursa-Wolf parameters serve two purposes:</p> |
| <ol class="verbose"> |
| <li><b>Fallback for datum shifts</b><br> |
| There is different methods for transforming coordinates from one geodetic datum to an other datum, |
| and Bursa-Wolf parameters are used with some of them. However different set of parameters may exist |
| for the same pair of (<var>source</var>, <var>target</var>) datum, so it is often not sufficient to |
| know those datum. The (<var>source</var>, <var>target</var>) pair of CRS are often necessary, |
| sometime together with the geographic extent of the coordinates to transform. |
| |
| <p>Apache SIS searches for datum shift methods (including Bursa-Wolf parameters) in the EPSG database when a |
| <a href="http://www.geoapi.org/3.0/javadoc/org/opengis/referencing/operation/CoordinateOperation.html?is-external=true" title="class or interface in org.opengis.referencing.operation" class="externalLink"><code>CoordinateOperation</code></a> or a |
| <a href="http://www.geoapi.org/3.0/javadoc/org/opengis/referencing/operation/MathTransform.html?is-external=true" title="class or interface in org.opengis.referencing.operation" class="externalLink"><code>MathTransform</code></a> is requested for a pair of CRS. |
| This is known as the <cite>late-binding</cite> approach. |
| If a datum shift method is found in the database, it will have precedence over any <code>BursaWolfParameters</code> |
| instance associated to this <code>DefaultGeodeticDatum</code>. Only if no datum shift method is found in the database, |
| then the <code>BursaWolfParameters</code> associated to the datum may be used as a fallback.</p> |
| </li> |
| |
| <li><b>WKT version 1 formatting</b><br> |
| The Bursa-Wolf parameters association serves an other purpose: when a CRS is formatted in the older |
| <cite>Well Known Text</cite> (WKT 1) format, the formatted string may contain a <code>TOWGS84[…]</code> element |
| with the parameter values of the transformation to the WGS 84 datum. This element is provided as a help |
| for other Geographic Information Systems that support only the <cite>early-binding</cite> approach. |
| Apache SIS usually does not need the <code>TOWGS84</code> element, except as a fallback for datum that |
| do not exist in the EPSG database. |
| </li> |
| </ol> |
| |
| <div class="section">Creating new geodetic datum 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). |
| Choice 1 in the following list is the easiest but most restrictive way to get a geodetic datum. |
| The other choices provide more freedom. |
| |
| <ol> |
| <li>Create a <code>GeodeticDatum</code> from one of the static convenience shortcuts listed in |
| <a href="../CommonCRS.html#datum()"><code>CommonCRS.datum()</code></a>.</li> |
| <li>Create a <code>GeodeticDatum</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#createGeodeticDatum(java.lang.String)" title="class or interface in org.opengis.referencing.datum" class="externalLink"><code>DatumAuthorityFactory.createGeodeticDatum(String)</code></a>.</li> |
| <li>Create a <code>GeodeticDatum</code> by invoking the <code>DatumFactory.createGeodeticDatum(…)</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>DefaultGeodeticDatum</code> by invoking the |
| <a href="#%3Cinit%3E(java.util.Map,org.opengis.referencing.datum.Ellipsoid,org.opengis.referencing.datum.PrimeMeridian)">constructor</a>.</li> |
| </ol> |
| |
| <b>Example:</b> the following code gets a <cite>World Geodetic System 1984</cite> datum: |
| |
| <blockquote><pre>GeodeticDatum datum = CommonCRS.WGS84.<b>datum</b>();</pre></blockquote> |
