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
Each 25K map covers a quarter of the corresponding 1:50,000 map, with the numbering system: I = NW quarter, II = NE quarter, III = SW quarter, and IV = SE quarter.
