80% infomation do not has a gis infomation?

From the university textbooks, the book is mentioned 80% of the world’s information contain relevant position information, this lets just contact GIS we feel this is how deep a discipline, so a large number of data volume and GIS relevant. From now on and others introduction up and learn professional, have to mention the world how many information and we learn major is relevant, let others think we learn is how professional. And ESRI \ Microsoft seemingly also has reference, but the data but put forward like do not know where they come from, who has done serious research statistics out…

This may need to carefully study the numerical, otherwise too kua geographic information important.
