How do we apply spatial thinking in GIS? Petch and Trodd outline some ideas and your task is to consider how those ideas might have been applied in some case studies.

How has spatial thinking been applied using GIS?
Keep a geographical diary for one day. Map a day in your life as it happens, identifying spatial events, processes and objects with which you interact.

The image shows a skydive track recorded using GPS. It corresponds to a 'freefly' dive, a high speed jump in a standing position with no horizontal movement. Note the gradual 135-point ascent... and the 8-point vertical descent!

Read Longley et al. (2001), Clark (1990), Nelson (1999) and Marceau (1999) and then demonstrate your understanding of spatial concepts and, in particular, the issue of scale.

Demonstrate your understanding of spatial concepts used in GIS.
How do you conceptualise the world around you? Do you use the same simplified version of reality in all your actions? I would be surprised if you did. For example, when we cross a park to catch a bus we think of different objects (paths, bus stops, bus routes) than when we go to the same park to read a book (quiet areas, benches) or play football (safe areas, open space, grass). But it's still the same park! What were the two different representations of topography identified by David Mark and Barry Smith?
