Cartography is a manifestation of visual culture. In the beginning of the 21st century, the technology that provides access to digital maps allowing them to be associated with all types of data, has opened up innumerable possibilities, contributing a new reference framework to architectural culture. This article presents the project of a digital platform, Interactive Atlas | Visual Register of Urban Architecture | Latin America 1940-1970, in which the map is its central element. Its aim is to visually articulate a collection of photographic materials of exceptional quality linked to a digital mapping base. A compendium that brings together architectural works relevant for their urban insertion in the cities of Latin America, from the 1940s to the 1970s, while discovering the legacy of a number of photographers from the mid-twentieth that historiography has related until now.
