Using Snapshots as input

[davidvaz]

Hello,

I am developing a GPS logs upload server and I will use mapserver to
show the covered area of the uploaded GPS logs.

As I am using shapefiles to store the logs, and I expect to have lots of
logs, the display of the covered area will become a bit slow.

My idea was to regularly take a snapshot of the covered area, and use it
as input, to simplify the processing.
Is there any way to do this?

Thanks in advance,

David Vaz
