Is this the whole Indoor area that the elephants have? If it is, it's quite small, maybe smaller than Cleveland's and Cleveland's indoor elephant exhibit is tiny. Its only 612 Square feet.
If the elephants spend 50% of their lives in that tiny space then I truly feel sorry for them. Zoo Atlanta built its elephant habitat in 1989, and now after 20 years it definitely is yet another pachyderm exhibit that is below par.
