Map No. 437 – Ateca is part of the topographic coverage of Spain at 1:50, 000 in the MTN50 (Mapa Topográfico Nacional) series from the Instituto Geográfico Nacional – Centro Nacional de Información Geograficá, 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 shown on topographic maps 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).A small inset shows local administrative boundaries & a table of UTM coordinates for triangulation points is also provided. Each map covers an area of 27x 18 km (17x 11 miles approx.) The maps have a 1-km UTM grid, with margin ticks for latitude & longitude at 5` intervals. Map legend is in Spanish only.*PLEASE READ THE NOTES BELOW BEFORE ORDERING!** Map Titles:* The grids shown on our website serve both the civilian & the military 1:50, 000 topographic series. Although the areas covered by sheets in both series are identical (apart from some border or coastal sheets), occasionally map titles differ – only one title is shown on the grid, usually the military one. Map titles listed on our website are based on information received by us at the time of publication, but sometimes maps arrive showing a completely different title! * As long as the map number is as ordered, the correct map has been supplied.* In Galicia, the Basque country & in the Catalan speaking areas the tendency now is to use local place names rather than the often better known Castilian names. Where possible, both versions are included in our titles. * Publication dates:*MTN50 series was begun in late 1990s, with most sheets listed here published in 2000s. Numbers not included on our website may still be available in the previous series but the maps will be very old, some dating back to 1940s or 1950s. If required, please contact us by e-mail.* How to choose the right 1:50, 000 map:* All the titles in the [LINK: 1800caption: IGN 200K Provincial Road Maps series at 1:200, 000] are overprinted with the grid for the 1:50, 000 maps & can be used to see precisely the area covered by each 50K title.
