A Series of 1:25,000 scale maps of Spain published by CNIG (The Centro Nacional de Información Geografica) - the equivalent of the Ordnance Survey 'Explorer' series in the UK.
About the map series
The MTN25 (Mapa Topográfico Nacional) series from CNIG (The Centro Nacional de Información Geografica) provide topographic coverage of mainland Spain at 1:25,000 – the Spanish equivalent of the Ordnance Survey Explorer series.
Each map covers approximately 14x9 km. The maps have a 1-km UTM grid, plus margin ticks for latitude and longitude at 1' intervals. The map legend is in Spanish only.
How to find the right map
