Shelter Camping

What do you call this type of camping shelter?

I went to sea cadets as a teenager. When camping, did not use tents. We just slept under waterproof rectangular sheets with a bungee cord hooked on every corner to stay between 2 trees or branches that had been dug on earth. Does anyone know the name for this type of housing?

Hey yerr am in cadets and their Basha called or poncho. Basha are only forward rectangular and ponchos to have a bit in the middle so im guessing up.But chain that is used Basha is 1 bungee from 1 tree and the other end attached to another tree and then simple, Basha goes up and out bound.
