Ocean Bottom Node surveys provide high quality data but, due to the higher cost of acquisition, lead to low coherency in common midpoint gathers. This makes the use of prestack depth imaging difficult. Even more, node data can be believed to be of little interest. We show here the opposite: not only it is possible to use node data for prestack depth imaging, but in addition, the obtained results are of very high quality. Such data requires furthermore very little preprocessing compared to more usual ocean bottom cable data. We present possible tools to image the subsurface from node data. A comparison between cable and node data on a real dataset from the North Sea shows the possible gain provided by node data.
