From Wikipedia I found the coordinates of the Devil's Tower, which is an oil platform in the Gulf of Mexico. The coordinates are 28°12′32″N, 88°44′15″W.
When I enter these coordinates into Google Earth, I see just the empty ocean, no gas platform.
I tried to do the same with some other oil platforms, such as Statfjord at 61°15′20″N, 1°51′14″E, and again I see nothing.
What is the reason for this? Is it just that the satellite images acquired of the oceans are low resolution?
