Topographic coverage of the Balearic Islands at 1:50, 000 in the MTN50 (Mapa Topográfico Nacional) series from the Instituto Geográfico Nacional – Centro Nacional de Información 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 & other protected areas are marked. In addition to all the usual information featured on topographic mapping at this scale: detailed presentation of the road & rail networks, rural tracks & paths, etc, the maps also show campsites & 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). The MTN50 series was begun in late 1990s. Each map covers 28.5x 18.5 km (with adjustments in the coastal areas). The maps have a 1-km UTM grid, plus margin ticks for latitude & longitude at 1` intervals. Map legend is in Spanish only. To see other titles in this series please click on the series link.
