In a way, yes. A map of the galaxy is called a star-chart, a star map, or an astronav chart, and they are used for navigating a ship through both hyperspace and realspace. (No special map is needed to navigate hyperspace; each point in realspace has an associated point in the alternate dimension of hyperspace, and every object in realspace has an associated “shadow” in hyperspace, so they are linked.) When a ship jumps to hyperspace, a star-chart is used to calculate a route to the destination that ensures the ship doesn’t collide with a celestial body. This is called astrogation.
