What exactly is Spatial Analysis ??

[Alastair Duncan]

Hello,

I was asked this morning by a colleague to concisely define spatial analysis,
and produce a list of techniques used by GIS that could be described as being
spatial analysis, all on one piece of paper. Having looked at my GIS textbook
collection I can't seem to find any real definitions - they are all very vague.
They all use the phrase extensively without actually saying what it means. Has
anyone got any ideas on this one ??

Cheers, Al.
