<p><strong>Remarks:</strong></p>
<ul>
<li><p>If a landmark or landmark category is to be edited, it must
exist in the database. Use the <a href="GUID-55591BBC-49F8-407D-98F5-1D2FCD5DFB34.html#GUID-55591BBC-49F8-407D-98F5-1D2FCD5DFB34"><code>GetList</code></a> method
to retrieve the ID of the landmark or landmark category.</p></li>
<li><p>If no landmark database is specified, <code>Add</code> is
performed on the default database. If the default database does not exist,
it is created and set active. The default database is <code>file://c:eposlm.ldb</code>.</p>
</li>
