Rilievo urbano con strumenti GPS: un’esperienza operativa nel quadrante ovest di Milano

This paper is reporting of a study at the urban scale, focused on the western quadrant of the city Milan of Expo 2015, where are highlighted the outcomes of some experiences of urban survey conducted using GPS devices. The study deals with the connecting routes and relationship between the city center and suburbs, with specific attention to the role of edges and other marginal open spaces of the territories, in between urban and still possible rural uses. The processing of geographic data through GIS also allows to understand some interesting issues related to highlight the points of interconnection with the transport system, such as the points of "uncertainty" present along the route, the actual feasibility/reachability of these places with respect to the centers of greater attraction of the city.
