Time interval (or isotime or isochron) maps are commonly used for interpreting changes in thickness between interpreted horizons ([[:file:mapping-with-two-dimensional-seismic-data_fig6.png|Figure 1]]). To map time intervals, calculate the difference in time (normally two-way time) between two events at each shotpoint and contour the resultant values.
