Old Maps of Madrid and Interactive Web Applications by National Geographic Institute of Spain

摘要

The Map Library of the National Geographic Institute of Spain (IGN), which was founded in 1870, has custody of an important cartographic collection of maps from the 16th century to nowadays, such as: maps made by the National Geographic Institute (national to- pographic maps or topographical works), regional maps, cartographic series, thematic map, atlases, city maps, and a valuable collection of maps of Madrid. The aim of this paper is to show a part of this cartographic heritage through different Madrid maps, that are available online, and to show how to use interactive IGN web applications for exploring the maps. Through a selection of the most significant old maps of Madrid, we can appreciate the evolu- tion of the urban development of this city. From the first printed map, drawn by Marcelli in 1622, which shows a city where the king Philip II moved the court in 1561; the magnificent map of Texeira, which is the most important and detailed city map of the 17th century; the Chalmandrier's map, 1761, that shows what the city looked like at the beginning of the Charles III's Kingdom; the Pascual Madoz and Coello's map, 1848, or the map of Iba.ez de íbero, 1875, where it is possible to appreciate the expansion of the district outside the wall that surrounded Madrid until 1875.
