<h2>Detailed Description</h2>
<p>The LandmarkProximityFilter element specifies a proximity filter for landmark model. Logical combinations of this and other landmark filters can be formed using <a href="qml-landmarkintersectionfilter.html">LandmarkIntersectionFilter</a> and <a href="qml-landmarkunionfilter.html">LandmarkUnionFilter</a>.</p>
<p>This element is part of the <b>QtMobility.location 1.1</b> module.</p>
<p>The following example creates a filter which filters for landmarks located within 1500 metres of the current position.</p>
<pre class="qml"> <span class="type"><a href="qml-positionsource.html">PositionSource</a></span> {
<span class="name">id</span>: <span class="name">myPosition</span>
<span class="name">updateInterval</span>: <span class="number">1000</span>
}
<span class="type">LandmarkProximityFilter</span> {
<span class="name">id</span>: <span class="name">landmarkFilterMyCurrentLocation</span>
<span class="name">center</span>: <span class="name">myPosition</span>.<span class="name">position</span>.<span class="name">coordinate</span>
<span class="name">radius</span>: <span class="number">1500</span>
