Geological field mapping represents a key stage of sedimentological and stratigraphic investigation. It is essential not only for reconstructing the depositional architecture and geological evolution of an area, but also to provide robust datasets useful to support the land-use planning and geological risk management. The precision and accuracy of field data acquisition are crucial for reliable stratigraphic and structural analyses, for the production of highresolution thematic maps and preliminary geological hazard assessments. In recent years, the introduction of digital technologies and mobile GIS platforms have deeply changed the traditional surveying methodologies. These tools enable more rapid, accurate, and standardised data collection, significantly enhancing operational efficiency and the overall quality of geological datasets. Within this framework, mobile GIS applications serve as innovative instruments for the in-situ acquisition of georeferenced data, minimizing transcription errors and facilitating the immediate integration of field observations into centralised databases. This paper presents a case study based on the implementation of a custom mobile application developed using ArcGIS Survey123, integrated with smartphone stock sensors—including a digital compass, accelerometer, and high-precision GPS. The application supports the completion of intelligent, customizable forms designed for specific categories of geological observations, including structural measurements, lithology, sedimentary facies, and stratigraphic geometries. This allows to a systematic collection of standardised data easily shareable. The application workflow was designed following the operational protocols of the Italian Geological Survey and was field-tested in southern Calabria within the Melito di Porto Salvo area. The study area is characterised by deformed and stratigraphically complex sedimentary successions, where accurate mapping of faults, folds, and lithofacies is crucial for deciphering local tectonic and sedimentary dynamics. The results demonstrate that employing mobile digital tools promotes systematic and integrated geological data acquisition. This approach effectively supports both detailed stratigraphic-structural analysis and thematic cartographic production, with direct implications for preliminary geological hazard evaluation and multi-hazard risk planning.
