Resolution enhancement

Definition

Resolution enhancement refers to techniques used to improve the clarity and detail of geophysical data, particularly in seismology, allowing for better interpretation of subsurface structures. By integrating data from multiple sources or methods, resolution enhancement increases the accuracy of imaging complex geological features and can reveal subtle details that would otherwise remain obscured.
