Regarding maps , we also classify plans, navigation charts that are presented in single sheets. The map collection comprises 26,322 sheets grouped into 2,874 cartographic documents. You must realise that a map may be presented in just one or more sheets. A large extent of the map holdings belongs to these kinds of maps. The desired level of coverage is maximum for Catalonia, gradually decreasing to cover the rest of Spain, Western Europe and the Planet as a whole.
Documents are analogical on paper support.
We also have some samples on digital support. Unfortunately, a limited diffusion imposed by the acquisition contract of digital maps in Europe does not let us have documentary holdings on this support. A map always shows interpreted territorial information to the user. However, aerial photographs and other images obtained from sensors offer a territorial representation that users have to interpret and decipher, and they can convert it into a map. Whit this purpose, the Map Library has 11,351 aerial photographs with the possibility of stereoscopy observation and corresponding to 64 flights between 1956 to now.
