* '''Motivation''': natural phenomena are, by essence, geolocalized. The flap of a butterfly's wing is more likely to cause a tornado in Oklahoma than in Lozère. Desert locusts are more likely to plague Ethiopia than Germany. Racial profiling and child hunger are more likely to occurr in some parts of the world than in others. How do we deal with such geographical information? Where and how do we store it, from frontiers between countries to vagaries of a lonely mountain trail? Should such information be private? Who should update it? How should we use it? One possible answer is [https://en.wikipedia.org/wiki/OpenStreetMap OpenStreetMap], a collaborative project to create a free editable map of the world. | * '''Motivation''': natural phenomena are, by essence, geolocalized.

* '''Beginners''': | |||
# download [https://josm.openstreetmap.de/ JOSM], a free software written in Java allowing to edit the content of the database OpenStreetMap (download the file "josm-tester.jar" in ~/bin) | |||
# open a terminal and launch it like this <code>java -jar ~/bin/josm-tested.jar</code> | |||
# inside JOSM, download all the data from a piece of the map (not too big, otherwise it will take too much time) | |||
# use Ctrl-w to remove symbols | |||
# start editing | |||
# if you want to commit your changes, you need to [https://www.openstreetmap.org/user/new create an account] on OSM | |||
