Abstract :This study investigates the integration of Geographic Information Systems (GIS) and Unmanned Aerial Vehicle (UAV) technologies in geosciences, focusing on geophysical applications. While GIS enables the management and spatial analysis of various data layers, UAVs allow for the rapid and cost-effective acquisition of high-resolution surface data. The synergy between these technologies enhances the modeling of geophysical processes and improves the effectiveness of risk assessment efforts. Supported by relevant literature, this integrated approach is exemplified through a case study conducted in the Buca-İzmir, Turkey. This application used photogrammetric methods to produce a digital surface model (DSM), followed by slope analyses in a GIS environment to identify potential landslide and ground failure zones. Subsequently, geophysical surveys were conducted to model the subsurface structures associated with these risks. The findings demonstrate that integrating GIS and UAVs provides a fast, precise, and holistic framework for geophysical engineering applications. Furthermore, the study presents a practical example of how these technologies can be effectively utilized in disaster risk reduction and land-use planning.
