I want to build a bathroom in the basement with a 36”x36” shower.
I am trying to figure out if this pipe is the vent from the main drain.

It is a vent, it is coming off of the top of a sanitary tee so it is a vent for a fixture (Bathroom sink) that would be attached to the SanTee.
The pipe coming form the bottom of the SanTee is the drain for a fixture that would be attached to it.
The hole in the floor should be the required space for a drain/trap for a shower/tub. Presumably since the sink plumbing and a toilet flange was roughed in there would be a capped off drain pipe under the dirt.
