Thanks for the quick answer. Just read your writeup on the subject [1]. This
looks like a _very nice_ addition and should be extremely helpful. I've got
some experimenting to do!

Question out ignorance because I was not aware that this capability existed.
I might have a geometry for a country and separate geometries for the next
layer of administrative regions (e.g. states in the United States). But there
are often minor differences in the polygons such that the polygo

PostGIS topology supports hirearchical modeling of layers, with each object
in upper layer defined by items of the lower lay

the optimal one is defined by your use case: the sorts of queries you want to
apply.

Actually what we need is some hierarchical base for relationship between
countries, cities, regions, etc. Main goal of the application will be
collecting data from many sources about specific cities, regions,
countries and so on, and store it in database. Let's say we will have city
Rome, we collec
for global roads & related spatial
data, which does not use Postgis at all.

Hi,
If you plan to use two tables of kind polygons and point, and don't plan to
use a
Thank's for your reply.
I think we'll go same ways as you describe - use two main tables `polygons`
and `points` and couple supporting tables which handle relationships
and additional content.

Hi,
we chhose by desing to use two table for the geometries (lines and
polygons).
And many tables to link the geometries inside these two tables.
