The Paris City Council maintains approximately 300,000 trees on his estate (parks and gardens, public roads, cemeteries, the Bois de Boulogne and Vincennes). Of these, some are distinguished by their age, rarity of their essence, their history or their impressive measurements: they are the remarkable trees. The mayor of Paris publishes licensed "Open Data" (License ODbL) data on 60 of the most remarkable trees of the capital. This application uses this data to help you discover these trees of exceptional heritage. You can access the information from each tree by a proximity search (list of trees around you), a map or through your camera for augmented reality. This application is offered by the group that performs applications free and open source Android (released under the GNU GPLv3). Respect for users, including their personal data is also a strong commitment of the group: this application contains no advertising and does not collect any personal information.
