\title Qt Location
\brief The Qt Location API provides mapping, navigation, and place search
via QML and C++ interfaces.
\ingroup technology-apis
The Qt Location API provides mapping, navigation, and place search via QML
and C++ interfaces.
The API has not been released yet but due to its platform-independent nature is available
on all Qt platforms.
\section1 Overview
The Qt Location API gives developers the ability to determine a position by
using a variety of possible sources, including satellite, or wifi, or text file,
and so on. That information can then be used to determine a position in a map
context with appropriate navigation and to embed, in the map, defined places
with descriptive metadata. These three parts
allow a device to know where it is and its location with respect to important
features. Using features such as roads, destinations, routes,
and other navigation attributes, applications can specify beginning and end-points
for navigation and awareness of objects that may aid or hinder a journey.
\section1 Getting Started
To load the Qt Location module, add the following statement to your .qml files
\code
import QtLocation 5.3
\endcode
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 API Sub-Modules
The API is split into sub-modules, which each have QML and C++ APIs. It focuses on
Map and Place information. The required position data can be retrieved via the
\l {QtPositioning} module.
\section3 Places
Places is
the natural complement to Positioning, providing a source of geographic
data about places of interest (POIs). As well as providing the location,
size and other vitals about a POI, the Places API can also retrieve images,
reviews and other rich content related to the place.

\li \l{QML Places API}{for QML}
\li \l{Places (C++)}{for C++}
\endtable
\section3 Maps and Navigation
Maps and Navigation provides Qt Quick user
interface components for displaying geographic information on a map, as
well as allowing user interaction with map objects and the display itself.
It also contains utilities for geocoding (finding a geographic coordinate
from a street address) and navigation (including driving and walking
directions).

example applications to demonstrate their usage.

be provided to influence their behavior.

Qt Location available for a new platform.

\section1 New Since Qt 4
In Qt 4 Qt Mobility provided some location functionality for Positioning and Maps
with Landmarks support. The new Qt Location API has had an extensive reworking
of \l {Map}s and \l {Place}s (formerly Landmarks). Also both C++ and QML APIs have
been reworked to be simpler to use.
New features of Qt Location includes
\list
\li Maps are now part of the Qt Quick scenegraph, and rendered using hardware-accelerated OpenGL
\li Arbitrary Qt Quick items on the map are supported using \l MapQuickItem
\li Now possible to create map overlays with a model
\li Built-in support for pinch-to-zoom gestures, flicking , and panning (see \l MapGestureArea)
\li Vast performance improvements over Qt Mobility 1.2, especially for large map polylines and objects in general
\li Full QML API now available for routing and geocoding -- compatible with standard QML model-view design
\li Service provider feature detection without having to open all the available plugins
\li Unified \l Plugin QML type used by routing/geocoding/maps etc with easy-to-set \l PluginParameter
\li Two plugins are supplied with Qt (a Nokia and an OSM plugin for GeoServices).
\li Landmarks API is replaced by the Places API
\li \l Place supports viewing of richer content such as reviews, images, and editorials
\li \l Place supports locale handling, sponsored search results, and supplier attribution
\endlist
