There is now posted a GPS plotting of the course of the Costa Concordia from the time of the initial collision to when she was run aground adjacent to Giglio Harbor: click her for GPS plotted Route

There is a video to click on for the GPS animation of "The Fatal Route" at the bottom of the page.

In summary the ship can be seen striking rocks off a prominent point, continuing on past Giglio Harbor and then circling clockwise so as to ground on ledges adjacent to the harbor lighthouse, a short distance from the inner harbor.

I'm still trying to put together a timeline from various reports.
