The week I arrived in Saint-Marc occurred the Night Of the Living Maps (NOTLM), a worldwide event within the OSM community, “where all mappers come together in local meetings and trace imagery the whole night long, while the moon shines bright!”. Groups form large and capital cities like Bogotá, Copenhagen, Madrid, Paris - Rome, Vienna, St. Petersburg orTokyo - were participating but also smaller ones like Esslingen, Mankato, MN , Passau or Rapperswil. Anyway, it was an excellent opportunity for the freshly trained young mappers of Saint-Marc to both figure out the power of the OSM community and show their own enthusiasm to the open source geodata.
