This unit has two primary segments: Unit 006 - Human Cognition of the Spatial World and Unit 007 - Asking Geographic Questions. The first section sets the scene by differentiationg between objects and processes and by  using fundamental understanding of the spatial world to provide a necessary knowledge  base for GIS. The second section builds on the knowledge base to demonstrate how specific  knowledge about objects and spatial relations among them can be unpacked by the  mechanism of asking geographic questions.
