Maybe this'll help @TheEAB:
"Where Ezra lives, where we meet him, the prairie that he lives on, the city, the town that it's adjacent to—all of that, literally down to what the alleys look like in the town—was inspired by Ralph's original art."
―Star Wars Rebels executive producer Simon Kinberg
http://herocomplex.latimes.com/tv/star- ... series/#/7Lothal does seem to be very earth like. The planet seen from space looks like Earth. However, the story seems to take place in a town that's side by side with a prairie. The town part does seem to generate a Tatooine like feel but I don't think the story has ever really been in the desert. Also, they've never really been by a significant body of water, even though from space great oceans can be seen.
