[Mapserver-users] how to restrict layers based on location?

[Dana Quinn]

Hi - I have a problem I'm not sure how to solve
within the mapfile.  I received high quality
data for one of the cities that display in our
application often.  I'd like to define a layer
that uses this high quality data when displaying
parts of this city, but uses the lower quality data
when not displaying parts of the city.

I guess getting the high quality data to NOT display
outside of the city isn't a problem, since the data
doesn't exist for locations outside of the city,
but I don't want the low quality data to show up
along with the high quality stuff in the city.
Is there a way to restrict what displays in the
way I've described in the mapfile?  I couldn't
really find any way to do this in the
documentation.
