You may find Virtual Moon Atlas a better resource. It has not only a finer scale, but also volcanic features which I've not seen in any other atlas, such as domes, vents and pyroclastic deposits. Below is a screen shot of the highest zoom-in on Clavius - kinda leaves Ruki's atlas rather pedestrian. The second is of Alphonsus, showing how many pyroclastic deposits there are in Alphonsus that are just not noted in any other atlases.
Virtual Moon Atlas is also a free download:
