<p>The <a href="GUID-D581028C-06ED-422D-866E-AE6C93075084.html#GUID-D581028C-06ED-422D-866E-AE6C93075084">Landmarks
Service</a> API is supported since <a href="GUID-1A3ECAC1-3F09-4602-A1CD-82164040A664.html#GUID-1A3ECAC1-3F09-4602-A1CD-82164040A664">WRT 1.1</a>.</p>
<p>The Landmarks Service API allows <span>widgets</span> to
access and manage information about landmarks and landmark categories. This
information is stored in one or more landmark databases on a device. The API
is integrated into <span>WRT</span> through the <a href="GUID-571AF37F-1E95-462A-92D2-FEA2E62F1559.html#GUID-571AF37F-1E95-462A-92D2-FEA2E62F1559"><code>device</code></a> object.</p>
<p>For an overview of the service and the API, see section <a href="GUID-D581028C-06ED-422D-866E-AE6C93075084.html#GUID-D581028C-06ED-422D-866E-AE6C93075084">Accessing and managing information about landmarks</a>.</p>
<div><h3>Using the Landmarks Service API</h3>
<p>To use the Landmarks Service API, your <span>widget</span> must
first create <span>a service object for it
using the <a href="GUID-04095E9A-50E7-4E5F-BD6F-71DA281A0080.html#GUID-04095E9A-50E7-4E5F-BD6F-71DA281A0080"><code>device.getServiceObject()</code></a> method</span>.
Use <code>Service.Landmarks</code> to identify the service provider
and <code>IDataSource</code> to identify the supported interface:</p>
<pre class="codeblock" id="GUID-84F1353D-4C82-4E45-934E-1EC67AD05CAA">var so = device.getServiceObject("Service.Landmarks", "IDataSource");</pre>
<p>This service object can then be used to access the services provided
by the API:</p>
<ul>
