As you're heading to the Desert Camp, if you follow the row of building to your left away from the camp and have the chip that shows item locations, there's a chest which is locked and you need 9S to open it. I can't figure out how to get to the top of the building on which it's located, though. There's a building across the street which you can get to by jumping on a bus then climbing on an A/C unit, but you can't jump/float far enough to reach the building.
I haven't encountered this exact chest yet, but the distance looks like it's definitely doable by jumping, though you have to do a special combo to maximize your distance.
In addition to sprinting, double jumping, and gliding with your Pod, attacking (square) once will thrust you upwards and forwards a bit, which should propel you to the other building.
I've since found the chest, so here is a video of me jumping to it:
If you're having trouble with mid-air combos, there's another way to boost your jumping distance:
Pod program A160: Missile, obtainable during route C (NG++). You can charge it for an extended boost. http://nierautomata.wiki.fextralife.com/A160:+Missile
Fist 40. Jump, hold x, while holding x press square, sq, sq, r2, x to jump, holding x square. Should clear it by half a building.
