Abstract:

The paper introduces an educational activity carried on within City Mapping class at the two-year Master Course in Architecture at the Department of Architecture and Industrial Design of the Università della Campania “Luigi Vanvitelli”. Class aims to bring students closer to the systems to city and land representation from the traditional to the innovative system, aimed at the production of maps and their use for urban design. Class dedicates a large part to Geographic Information Systems for the acquisition, representation, processing, and management of spatial data.

The need to acquire and survey a large quantity of information in the field required the use of platforms that would allow not only the recording of data but also their geolocation and their immediate interface with the information database. The students were involved in the creation of a census table elaborated to be able to collect all the descriptive information in a first step. This information was acquired from the in situ survey, associating alphanumeric data, photographic images (general and detail) of the elements surveyed, in addition to acquisition data and the exact geographical position automatically measured by the GPS / GNSS antenna inside the smartphone device used for survey. The acquired information allowed the population of the data of the attribute table associated with a digital level of the GIS project, in which the thematic layer referred to the acquired data, associates the information with the geometry of the point, polyline or polygon with reference to the size of the element detected as a function of the urban scale.

Census activity, from the acquisition of the data to its processing, was carried out through a GIS platform that could collect all the data in a geographical database. The GIS project developed by the students was carried out through both open data geographical information and open-source software and apps, with a view to a future enhancement and continuous implementation of information and its sharing to other users through the web.
