== Reverse geocoding ==
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 use the <tt>MarbleRunnerManager</tt> class to get a textual description of a given coordinate.

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

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

using namespace Marble;

int main(int argc, char** argv)
{
QApplication app(argc,argv);
MarbleWidget *mapWidget = new MarbleWidget;
MarbleModel *model = mapWidget->model();

MarbleRunnerManager* manager = new MarbleRunnerManager( model->pluginManager() );
manager->setModel( model );

GeoDataCoordinates position( -0.15845, 51.52380, 0.0, GeoDataCoordinates::Degree );
qDebug() << position.toString() << "is" << manager->searchReverseGeocoding( position );
}
</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</tt> and the output looks similar to this:
<source lang="text">
" 0° 09' 30.4"W, 51° 31' 25.7"N" is "Sherlock Holmes Museum, "221b", Baker Street, Marylebone, City of Westminster, Greater London, England, NW1 6AX, United Kingdom"
</source>

{{tip|
Here's a little checklist to tackle some problems that might arise when compiling the code above:

* You need Qt and '''Marble development packages''' (or comparable git installations), version 1.3 (Marble library 0.13), shipped post KDE 4.8
* If ''Qt headers'' are not installed in '''/usr/include/qt4''' on your system, change the path in the g++ call above accordingly.
* Likewise, '''add -I /path/to/marble/headers''' if they're not to be found in /usr/include
}}
