Free access web-based mapping is nowadays largely used in several areas such as navigation, location-based services or when it is necessary to obtain quickly geographical information.

Abstract

Free access web-based mapping is nowadays largely used in several areas such as navigation, location-based services or when it is necessary to obtain quickly geographical information. Some of them are based on volunteers' work, among which OpenStreetMap (OSM), while some others were design for commercial purposes, such as Google Maps (GM). Given the variety of contributors and their heterogeneity, one of the critical aspects of OSM is the homogeneity and quality level of its information; furthermore, GM is also largely consulted but presents inhomogeneity between densely populated and rural areas. The paper aims at analysing the buildings completeness of OSM and GM over the Province of Pavia, in Northern Italy: the applied method will be presented together with the results obtained at two different time frames (spring 2018 and winter 2018). Finally, a quick review about the volunteers that had effectively contributed to OSM will be presented.
