Abstract

Two large VLBI surveys are currently underway which utilise the snapshot technique pioneered on the VLA. With a 12–16 telescope array three ~ 20 min snapshots are sufficient to make excellent hybrid maps. Recent advances in data analysis techniques enable surveys of several hundred sources to be undertaken and reduced in under two years.
