[pstricks] Selcting \rput commands

I have been using pstricks to create cartographic maps e.g.
{\psset{unit=1600pt}
\pspicture*(3.00000,2.30000)(3.26000,2.62000)
\input symbols.dat
\endpspicture
}
The file symbols.dat contains a list of records created from a database in
the form
\rput(3.31667,2.34189){\mysymbol}
where \mysymbol is a custom symbol created in a \pspicture environment of
which I have around fifty separate examples.
My problem is that when I zoom in on my map e.g.
{\psset{unit=5000pt}
\pspicture*(3.12700,2.48000)(3.20000,2.60500)
\input symbols.dat
\endpspicture
}
I get the error dimension too large for obvious reasons. However since the
offending \rput commands fall outside the range of the \pspicture
environment I do not need them.
My question is, how can I read the file symbols.dat yet ignore all \rput
commands which fall beyond the range of the \pspicture environment.
Yours,
Adam Fenn.
