I have a 1 GB shapefile (yes, 1 GB!), as it is the footprints for
ALL the IKONOS satellite imagery for the entire world. Other than
breaking up the file, using the native shapefile in Cartoweb and
querying it would probably take a LONG time. Is storing this file
in a PostgreSQL/PostGIS Spatial database any faster? I understand
you can index the file in the database version to speed up searches
etc., but is this file just way too big to begin with no matter
which method I use?
Anyone have experience with working with a shapefile this big and
trying to access it over Cartoweb? Or the speed difference using a
spatial DB?
Hi
I think it is worth reading this postgis post regarding this issue:

Personnally, I think using postgis as repository is a good choice.
Well crafted index will help querying the data
