\qtvariable location
\brief Provides C++ interfaces to retrieve location and navigational
information.
The C++ API provides access to geocoding and navigation information,
and also place search. Use the \l{Maps and Navigation (QML)}{QML}
API to render this information on an interactive map that supports
touch gestures, overlays, and so on.
Include the appropriate header in your C++ code. For example,
applications using routes can include:
\code #include <QGeoRoute> \endcode
Add the \e location keyword in the project file to link against the
Qt Location library:
\code QT += location \endcode
See more in the \l{Qt Location}{Qt Location Overview}.

\title Qt Location
\brief Provides QML and C++ interfaces to create location-aware
applications.
\ingroup technology-apis
The Qt Location API helps you create viable mapping solutions using the data
available from some of the popular location services.
\section1 Overview
The Qt Location API enables you to:
\list
\li access and present map data,
\li support touch gesture on a specific area of the map,
\li query for a specific geographical location and route,
\li add additional layers on top, such as polylines and circles,
\li and search for places and related images.
\endlist
\section1 Getting Started
To load the Qt Location module, add the following statement to your .qml files
\code
import QtPositioning 5.5
import QtLocation 5.6
\endcode
The QtLocation QML module depends on the QtPositioning QML module.
Therefore every QML application that imports the QtLocation QML module must always
import the QtPositioning module as well.
For C++ projects include the header appropriate for the current use case,
for example applications using routes may use
\code #include <QGeoRoute> \endcode
The .pro file should have the \e location keyword added
\code QT += location \endcode
\section2 Submodules
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 \l {QtPositioning} module.
\section3 Places
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.

\li Places introduction:
\li \l{QML Places API}{for QML}
\li \l{Places (C++)}{for C++}
\endtable
\section3 Maps and Navigation
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.

\li \l{Maps and Navigation (C++)}{for C++}

with example applications to demonstrate their usage:
