[Mapserver-users] postgis and 4d data in mapserver

[David Bitner]

Off topic at first, but there are a number of PostGIS folks here too:

I am looking at using postgis to work with airport traffic data.  As part of
this I need a time and elevation component.  What is the best way to work
with four dimensional data in postgis?  What is an example of a query that
would access either the elevation or the time component of the geometry?

The next step of course, is creating a mapserver app. perhaps with flash, to
display an animation of flights going over an area over a certain period of
time.  And also to be able to select the flight tracks by a line to get a
cross section of the elevations the planes are at a certain point.  But,
it's sometimes best to take things one step at a time.  Any and all pointers
of course would be greatly appreciated.
