Surface Mapping

Definition

Surface mapping is the process of creating detailed representations of the Earth's surface using various geophysical, geological, and geochemical data. This technique allows scientists to visualize the distribution of different geological features and resources, helping to identify patterns and relationships among them. Surface mapping plays a crucial role in understanding subsurface structures and assists in integrating multiple forms of data for comprehensive analysis.
