I have not got extensive experience with the mysql spatial, but from my
limited experience (possibly now a bit dated) mysql have implemented
spatial data warehousing with pretty good query performance per the
OGC specs.  Last time I looked they had not implemented complex spatial
operations (like intersection) and had not done anything with coordinate

I see the docs still indicate that the mysql functions for things like
distance and intersects are still implemented using the MBRs rather than
the actual geometry.

It would be suitable, for instance, for straight forward web mapping
applications but it would not be a good data analysis environment for

Hopefully there will be some deeper answers forthcoming.
