Qt Mobility Geoservices Extras

This package contains additional geoservices for Qt Mobility providing integration with OpenStreetMap and Google Maps.

Example

QMap<QString, QVariant> parameters;

parameters["mapping.servers"] = (
  QStringList("http://a.tile.opencyclemap.org/cycle/")
    << "http://b.tile.opencyclemap.org/cycle/"
<< "http://c.tile.opencyclemap.org/cycle/");

if (serviceProvider)
    delete serviceProvider;

serviceProvider = new QGeoServiceProvider("openstreetmap", parameters);

if (serviceProvider->error() != QGeoServiceProvider::NoError) {
    QMessageBox::information(
    this, tr("Error"),
        tr("Unable to find the %1 geoservices plugin.").arg(providerId));
qApp->quit();
return;
}

mapManager = serviceProvider->mappingManager();

OpenStreetMap (openstreetmap)

API

OpenStreetMap creates and provides free geographic data such as street maps to anyone who wants them. The project was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive, or unexpected ways.

Parameters

mapping.servers:
    type:           QString / QStringList
    default:        http://tile.openstreetmap.org/
    description:    openstreetmap tile server(s)
                    if a list is specified, the manager will used
                    round robin to balance request between servers.
                    The trailing slash is *needed*.
                    Examples:
                     Use two servers: ("http://a.tile.openstreetmap.org/",
                                       "http://b.tile.openstreetmap.org/")

Google - Static Map (experimental/google EXPERIMENTAL)

This is an attempt to use static Map API, but it does not work well right now.

API

The Google Static Map service creates your map based on URL parameters sent through a standard HTTP request and returns the map as an image you can display on your web page.

Parameters

mapping.proxy:
    type:           QString
    default:        application global proxy settings
    description:    http proxy used for network queries [host[:port]].
                    default port is 8080.

mapping.cache.directory:
    type:           QString
    default:        temporary directory
    description:    Cache directory.

mapping.cache.size:
    type:           long long (or QString)
    default:        default QNetworkDiskCache cache size
    description:    cache size, may be limited by the platform.

mapping.sensor:
    type:           bool
    default:        false
    description:    specifies whether the application requesting the static
                    map is using a sensor to determine the user's location.

mapping.tilesize:
    type:           QSize
    default:        QSize(256, 256)
    description:    size of the files, size can be as big as
                    640x640. Tweak the size according to the size
                    of your screen and your network configuration.
                    256x256 is the recommended size.

mapping.format:
    type:           QString [png8, png32, gif, jpeg jpeg-baseline]
    default:        none (server default: png32)
    description:    choose the format of the tiles
                    - png8 or png (default) specifies the 8-bit PNG format.
                    - png32 specifies the 32-bit PNG format.
                    - gif specifies the GIF format.
                    - jpg specifies the JPEG compression format.
                    - jpg-baseline specifies a non-progressive JPEG compression format.

mapping.language:
    type:           QString
    default:        none
    description:    defines the language to use for display of labels on map tiles.
                    Note that this parameter is only supported for some country tiles;
                    if the specific language requested is not supported for the tile set,
                    then the default language for that tileset will be used.
                    Examples: fr-FR, en-US, ...
