This map is considered as the "prototype" of the map of Ukraine that was printed in Gdańsk in 1650.  One characteristic of this map is that much of it is blank and courses of even major rivers are missing. This is aclear evidence that Beauplan, by 1635, did not yet have time to prepare a proper cartographic survey of the entire area. Moreover, it is obvious that parts of this map are missing. The best example is the half cartouche at the bottom of the map. It is 
also uncertain whether any land surveys had been completed on the left bank of the Dnipro River.
