Index Map Mexico City

The Index Maps are part of the Aerial Collection of the Historical Archive of ICA Foundation. This mapping designed by the Mexican Aerofoto Company as a planning instrument for aerial surveys and territorial planning represents the total coverage of an overflight that was schematically represented. Aerofoto made maps in blueprints, diazotypes, railway printing, Van Dyke brown printing, photostat and zerography. The collection has 1,682 copies and is the origin of flights made for both Oblique and Vertical photographs. This map of 1936 is the oldest in the collection and shows the first years of Mexico City's urbanization at the time the Distrito Federal Government established the regulatory plans of 1933 and 1935. The map shows the elevation of the flight to 1: 500,000 while the lines in the west-east direction they represent the route of the plane.
