Abstract
This paper (Part 2) describes some characteristic aspects of spatial cognition with regard to an initial instruction as the environmental information to a subject which is given at the origin(O) of his/her navigation through an area of irregular street network. With regard to the type of initial instruction given at the O, the sketch map which was drawn immediately after the round trip between O-D was analysed from the view point of the spatial cognition about the structure of O-D relationship, lack or filling of streets, and style and procedure of drawing.
