Recently, the integration of Ground Penetrating Radar (GPR) and Drone data with Geographic Information Systems (GIS) has garnered global attention among scientists. This integration offers significant advantages, including efficient data storage, organization, archiving, interactive 2D and 3D mapping, and rapid information retrieval. However, many researchers primarily focus on above-ground mapping and manual integration. In this study, a comprehensive approach involving GPR, Drones, GIS, and a 3D Web Application was employed to locate and map burials in the New Light Cemetery. Furthermore, a Python tool was developed to automate the integration of GPR information into the GIS underground system. The results demonstrate the effectiveness of this multifaceted approach in efficiently locating and mapping burials. The innovative Python tool can be applied to map subsurface targets accurately in their respective 3D spatial locations. The implications of this study extend beyond burial mapping, offering a valuable resource for integrators aiming to save time and reduce errors in various applications, including geophysical, geological, and engineering domains.
