It's a Ferris wheel.

The process of identification for this image is based on the geospatial intelligence tradecraft of shape, shadow and context.

The Ferris wheel is more difficult to identify due to the overhead perspective of satellite imagery. By observing the shadow it casts, features such as a crane and lattice tower can be ruled out, while examining the surrounding features provides context on what its function might be.

The lack of industrial infrastructure further rules out it being a crane, and the absence of nearby significant parking or accommodation infrastructure reduces the likelihood of it being a casino or shopping complex.
