[GRASS5] Temporal data in GRASS?

[Carl Worth]

Greetings,

I'm interested in working with some GIS data that has a rather dynamic
temporal element. For example, I plan to record the location of
various moving objects, (via GPS), and later I'd like to replay this
data in GRASS.

I've considered doing something as simple as storing timestamped data
in a database and looping through the query results, displaying
successive images. But, I wonder if a more integrated solution might
not be more desirable.
