New page

= Exporting OSM =
Osm files can be used for creating small street maps or can be scaled to store streets worldwide. OSM files can be exported from [http://openstreetmap.org OpenStreetMaps] by clicking the export button as shown below.

= Loading OSM files into a Marble Widget =

Marble uses so-called runners to calculate routes, do reverse geocoding, parse files and search for placemarks (cities, addresses, points of interest, ...). This tutorial shows how to open a .osm file and display it into the Marble Widget.

<source lang="cpp-qt">
#include <QtCore/QDebug>
#include <QtCore/QFileInfo>
#include <QtGui/QApplication>

#include <marble/MarbleWidget.h>
#include <marble/MarbleModel.h>

using namespace Marble;

int main(int argc, char** argv)
{
QApplication app(argc,argv);

QFileInfo inputFile( app.arguments().last() );
if ( app.arguments().size() < 2 || !inputFile.exists() ) {
qWarning() << "Usage: " << app.arguments().first() << "file.osm";
return 1;
}

MarbleWidget *mapWidget = new MarbleWidget();
mapWidget->setMapThemeId("earth/openstreetmap/openstreetmap.dgml");

mapWidget->centerOn( GeoDataCoordinates( 77.5674, 12.9782, 0, GeoDataCoordinates::Degree ) );
mapWidget->zoomView( 3000 );

mapWidget->model()->addGeoDataFile( inputFile.absoluteFilePath() );

mapWidget->show();

return app.exec();
}</source>

Copy and paste the code above into a text editor. Then save it as <tt>my_marble.cpp</tt> and compile it by entering the following command on the command line:

<source lang="bash">
g++ -I /usr/include/qt4/ -o my_marble my_marble.cpp -lmarblewidget -lQtGui -lQtCore
</source>
If things go fine, execute <tt>./my_marble some-file.osm</tt> and you get a Marble Widget which displays your OSM file. For example, download and unpack [http://techbase.kde.org/images.techbase/5/51/Map.tar.gz Map.osm] (a [http://api.kde.org/4.x-api/kdeedu-apidocs/marble/html/classMarble_1_1GeoDataLinearRing.html LinearRing] representing Bangalore city junction), place it in the same folder as your <tt>my_marble.cpp</tt> file and run <tt>./my_marble map.osm</tt>. The result should be similar to this:

The placemarks are clickable and triggers a dialog. The Screenshot below is of the dialog for Bangalore City Station triggered by clicking it on the map.
