MTN Grids

A description of the MTN (Mapa Topografico Nacional) grids available:

MTN25_ED50_Peninsula_Baleares

MTN25 grid corresponding to the Peninsula and Balearic Islands, in ED50 and geographical coordinates (longitude, latitude) This is the real MTN25 grid, that is, the one that divides the current printed series of the map, taking into account special sheets and irregularities.

MTN50_ED50_Peninsula_Baleares

MTN50 grid corresponding to the Peninsula and Balearic Islands, in ED50 and geographical coordinates (longitude, latitude) This is the real MTN50 grid, that is, the one that divides the current printed series of the map, taking into account special sheets and irregularities.

MTN25_ETRS89_ceuta_melilla_alboran

MTN25 grid corresponding to Ceuta, Melilla, Alboran and Spanish territories in North Africa, adjusted to the new official geodetic reference system ETRS89, in geographical coordinates (longitude, latitude).

MTN25_ETRS89_Peninsula_Baleares_Canarias

MTN25 real grid corresponding to the Peninsula, the Balearic Islands and the Canary Islands, adjusted to the new ETRS89 official reference geodetic system, in geographical coordinates (longitude, latitude).

MTN50_ETRS89_Peninsula_Baleares_Canarias

MTN50 real grid corresponding to the Peninsula, the Balearic Islands and the Canary Islands, adjusted to the new ETRS89 official reference geodetic system, in geographical coordinates (longitude, latitude).

MTN25_RegCan95_Canarias

MTN25 grid corresponding to the Canary Islands, in REGCAN95 (WGS84 compatible) and geographic coordinates (longitude, latitude). It is the real MTN25 grid, that is, the one that divides the current printed series of the map, taking into account the special distribution of the Canary Islands sheets.

MTN50_RegCan95_Canarias

MTN50 grid corresponding to the Canary Islands, in REGCAN95 (WGS84 compatible) and geographic coordinates (longitude, latitude). This is the real grid of the MTN50, that is, the one that divides the current printed series of the map, taking into account the special distribution of the Canary Islands sheets.
