OFFICIAL FRENCH MAPS. The green 🔍 Search Maps button opens a second map with three base layers: OSM (OpenStreetMap), Plan IGN — France's official national map from the Institut national de l'information géographique et forestière — and Photos, the IGN's aerial photography. Two overlays go over any of them: Contours, the IGN's contour lines, and Relief, hillshading from the RGE ALTI one-metre terrain model. The search box finds any place in France or beyond by name.
Click Grid to overlay the UTM grid — one-kilometre squares at normal zoom. Click Measure and tap two points for the distance plus the grid, true and magnetic bearing.
📍 My position takes a single GPS reading and shows it as an MGRS reference, as plain UTM, as Lambert-93 (the French national grid, EPSG:2154) and as latitude and longitude, with a Copy position button. Map tiles need mobile coverage; a GPS reading does not.
Mode d'emploi. Les boutons Map et Satellite basculent entre le plan et la vue aérienne ; + et − zooment. Le bouton vert 🔍 Search Maps ouvre une seconde carte avec OSM, le Plan IGN (la carte officielle de l'IGN) et les Photos aériennes de l'IGN, ainsi que deux calques : Contours (courbes de niveau) et Relief (ombrage RGE ALTI).
Grid affiche le quadrillage UTM, Measure mesure distance et direction, et 📍 My position indique votre position en MGRS, en UTM et en Lambert-93 — même sans réseau pour les tuiles de la carte.
