Topographic survey of France at 1:25,000 in IGN's excellent TOP25 / Serie Bleue series. All the maps are GPS compatible, with a 1km UTM grid plus latitude and longitude lines at 5' intervals. Contours are at 5m intervals except for mountainous areas where the maps have contours at 10m intervals, vividly enhanced by hill shading and graphics for rocky terrain. Colouring with graphics indicates different types of vegetation or land use (deciduous or coniferous forests, moors, orchards, vineyards, etc).
