Nolli’s Map of Rome, (Learning from Las Vegas, 1972)
Learning from Las Vegas (Venturi, R., Scott Brown, D., Izenour, S. 1972) is an example of a research project that led to new ways of thinking about design. In 1968 the researchers and a group of students spent ten days in Las Vegas with free board and lodging at the Stardust Hotel. Having spent three weeks in the library they carried out observational research recording the characteristics of the town.
The surveys were designed to explore the relationship between; movement, iconography and public space in the car orientated landscape of the Las Vegas strip. Each element was recorded as layer of a map recording the disposition of: undeveloped land, asphalt, autos, buildings, ceremonial space and finally ‘Nolli’s Las Vegas’ which brought the layers ‘asphalt’ and ‘ceremonial spaces’ together to show how the commercial strip was structured as a series of public places.

Since then designers routinely use layers to observe and analyse the key features of a site, adapting and extending this set of layers to describe a design proposal. Some layers record a general background understanding of the site but some like the layers in Learning from Las Vegas are much more specific about the particular drive of the project or the specific character of a place.
