hi,

I have to query many contiguous layers containing a large number of
roads. What I want to do is a query in which i'd like to retain only the
layers containing the roads that fall within a particular polygon. The
problem is that I have to repeat this query for each of the layers,
which could be time consuming.

I came with an idea that I could clip a region around my polygon and
then do the same query only on the road layers still visible within the
clipped region. Is this a dream or is it possible to do it? If yes, what
is the syntax to achieve correct results?

Thanks in advance for answering,
