Photos that purport to be of the map of Jurassic World's version of Isla Nublar have leaked. There's no way to know if they're real or, if they are, what role they'll actually play in the film. But they do paint the picture of a dinosaur-laden island.
These photos were posted to the Jurassic Park Legacy Forum and come from an anonymous source, with no details about how they got them. So, as usual, take anything that's not official or clearly public knowledge with the requisite grain of salt.
If they are real, we don't know if the map is of a not-yet completed park, a completed park that's been abandoned, or a still-open park. If the leaked plot is true, then the park is open for business, but flagging in popularity.
