GeoTree is a new hierarchical toponym browser for GeoNames. It allows to drill down the continents and the administrative divisions of a country in an explorer like fashion. To the right of the tree view a map shows the toponym selected. An outstanding component of GeoTree are the flags and coat of arms displayed with most administrative features. The coat of arms are from the wikipedia Blasons (heraldry) project. Moving the mouse over the name of an administrative division will not only focus the map, it will also display a larger version of the coat of arms.
The GeoNames balloons are linking to the respective GeoTree representation of the toponym. GeoTree is using the GeoNames hierarchical webservices.
