The term roll comes from a mechnical switch known as a roll switch (rota-long by I/O was common) that allowed one to add more active receiver stations as the source locations got further from the edge of the seismic program. This is unlike walk on where the roll switch remained constant until the shooter had walked into the nominal geometry location whereas the observer began rolling the spread via the roll switch.

Adquirir datos al principio (o al final) de una línea sísmica en la que la multiplicidad aumenta (o disminuye) gradualmente con respecto a la multiplicidad nominal de la línea.

The term roll comes from a mechnical switch known as a roll switch (rota-long by I/O was common) that allowed one to add more active receiver stations as the source locations got further from the edge of the seismic program. This is unlike walk on where the roll switch remained constant until the shooter had walked into the nominal geometry location whereas the observer began rolling the spread via the roll switch.
