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

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.
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/")
OpenCycleMaps: ("http://tile.opencyclemap.org/cycle/")
mapping.server: alias for mapping.servers
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.

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

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.

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, ...
