(b) Flow chart explaining the "ISOLINE" prototype
Object Oriented Expert System in G.l.s. - (a) The "NETWORK" prototype is able to model
the networks of all the geographical phenomena, the only differences come from the content of
the three large hyperclasses respectively named "Vertex_furniture", "Pointjurniture" and
"Linear_component"; (b) The "ISOLINE" Prototype is a general structure which is able to
model any phenomenon represented by prototypes in Geophysics as well as in Topography or
Meteorology. (After Bouille, see page 245) .
