ABSTRACT: This research investigates the efficacy of OpenStreetMap (OSM) and Geographic Information Systems (GIS) for rapidly identifying and cataloging masonry bridges in specific regions integrating modern technology with historical data to enhance the mapping and preservation of these critical structures. The methodology developed is based on the use of OSM, Google Street View (GSV), and the Overpass API. It includes data extraction, processing, and validation through intrinsic and extrinsic quality measures, highlighting the robustness of masonry bridges, particularly in historical areas where traditional construction techniques prevail. The experimentation was carried out on an area of 1.225 km² in the province of Pescara (Italy). The results showed an accuracy rate of 74.35% in identifying bridge types from street-level images, despite the crowd-sourced nature of the data demonstrating the potential of combining open-access geospatial data with modern verification tools to support infrastructure mapping and preservation efforts, providing a comprehensive and cost-effective approach, especially in regions with deficient geospatial data.
