Physical Mapping of urban environments This project aims to create an easy-to-build kit for the representation of urban structures. Based on three main concepts as modules like: nodes, relations and environment, which can be used to examine and understand how cities and urban centers work, and propose new ways of relations based in a physical observation. Usually urban studies have been subjected to the image representation of the reality, some times trying to imitate phenomena some other times trying to abstract it in a extreme way. Because the use of the computer urbanism, architecture and city planning now are subjected to: physical representation through prototypes, static scaled buildings, and non physical representation meaning the use of rendering machines and modeling software.
