This manuscript presents a methodology for 3D cadastral modeling by integrating low-cost sensor technologies, such as drone-based photogrammetry, with authoritative geospatial datasets. The approach is designed to overcome the limits of conventional 3D data acquisition, which can be highly resource-consuming. The workflow proposed in this research encompasses multisource data integration, such as data cleaning, georeferencing, and the alignment of 3D geometries with legal parcel boundaries. The resulting models are suitable for visualization and cadastral verification, offering practical tools to enhance land administration practices. It may also be used as the basis of 3D building representation or volumetric cadastre. To demonstrate its applicability, our proposed methodology is applied to a property located on the bank of a river in rural Québec, away from major urban centers.
