<p>The Qt Location API helps you create viable mapping solutions using the data available from some of the popular location services.</p>
<p>The release of this API with Qt 5.5 is a Technology Preview. This implies a soft API freeze for Qt Location.</p>
<a name="overview"></a>
<h2 id="overview">Overview</h2>
<p>The Qt Location API enables you to:</p>
<ul>
<li>access and present map data,</li>
<li>support touch gesture on a specific area of the map,</li>
<li>query for a specific geographical location and route,</li>
<li>add additional layers on top, such as polylines and circles,</li>
<li>and search for places and related images.</li>
</ul>
<a name="getting-started"></a>
<h2 id="getting-started">Getting Started</h2>
<p>To load the Qt Location module, add the following statement to your .qml files</p>
<pre class="cpp">import <span class="type">QtPositioning</span> <span class="number">5.5</span>
import <span class="type"><a href="qtlocation-module.html">QtLocation</a></span> <span class="number">5.5</span></pre>
<p>The <a href="qtlocation-module.html">QtLocation</a> QML module depends on the QtPositioning QML module. Therefore every QML application that imports the <a href="qtlocation-module.html">QtLocation</a> QML module must always import the QtPositioning module as well.</p>
<p>For C++ projects include the header appropriate for the current use case, for example applications using routes may use</p>
<pre class="cpp"><span class="preprocessor">#include <QGeoRoute> </span></pre>
<p>The .pro file should have the <i>location</i> keyword added</p>
<pre class="cpp">QT <span class="operator">+</span><span class="operator">=</span> location</pre>
<a name="submodules"></a>
<h3 >Submodules</h3>
<p>The API is split into sub-modules, which provide QML and C++ interfaces for specific purposes. They focus mainly on Map and Place information. The required position data can be retrieved using the QtPositioning module.</p>
<a name="places"></a>
<h4 >Places</h4>
<p>The Places submodule is the natural complement to Positioning, providing a source of geographical data about Places of Interest (POI). Besides the source information, the API provides information about the location, size, and other related information about a POI. The Places API can also retrieve images, reviews, and other content related to a place.</p>

<tr valign="top" class="odd"><td >Places introduction:</td><td ><a href="location-places-qml.html">for QML</a></td><td ><a href="location-places-cpp.html">for C++</a></td></tr>

<a name="maps-and-navigation"></a>
<h4 >Maps and Navigation</h4>
<p>The module provides the QML and C++ alternatives for maps and navigation. The C++ alternative provides utility classes to get geocoding (finding a geographic coordinate from a street address) and navigation (including driving and walking directions) information, whereas its QML counterpart provides UI components to render the information.</p>
