− | Contours are lines on maps which connect equal values. These may be elevations ([[Subsurface maps#Structure|structure maps]]), true thicknesses ([[Subsurface maps#Isopach|isopachs]]), measured thicknesses ([[Subsurface maps#Isochore|isochores]]), differences between two seismic events or reflections ([[Subsurface maps#Isochron|isochrons]]), or any variables that can be mapped.
