Spain: 50K Mainland Spain Civilian Topographic Survey

Topographic coverage of mainland Spain at 1:50,000 in the MTN50 (Mapa Topografico Nacional) series from the Centro Nacional de Informacion Geografica, the country's civilian survey organization. The maps have contours at 20m intervals, enhanced by relief shading, plus colouring and/or graphics to show different types of terrain, vegetation or land use. Boundaries of national parks and other protected areas are marked. In addition to all the usual information featured on topographic mapping at this scale, detailed presentation of the road and rail networks, rural tracks and paths, etc, the maps also show campsites and mountain refuges. On more recent editions some GRs, the official long-distance hiking routes, are also marked (although not as clearly as on hiking maps from other publishers). Each map covers 29.5x18.5 km (with adjustments in the border or coastal areas). The maps have a 1-km UTM grid, plus margin ticks for latitude and longitude at 1' intervals. Map legend is in Spanish only.
