Three-dimensional terrain reconstruction for applications such as geodetic modeling and spatial analysis remains challenging when GNSS-derived observations are sparse, distributed primarily along road networks, and referenced to a vertical reference system different from that of the available digital terrain models (DTMs). This study presents a methodology for integrating GNSS-derived road observations with raster-based terrain models to reconstruct continuous and geometrically consistent terrain surfaces while pr...
