[Mapserver-users] finding extents of polygon in shapefile

[mapserver@digger.net]

I am using MapServer 4 with PHP 4 (but not MapScript).  I am looking for a
way to quickly find the extents of polygon(s) in a shapefile.  In a nutshell,
I am using the Tiger PLC00 data, and would like to be able to take a city
name and look up the extents of the polygon(s) for that city so that I can
set the extents of the map to display just that city.

I've tried playing with '-where' in ogrinfo, but even when I restrict the
results to just one city, the displayed extents are still for the entire file.

Any suggestions how I might do this?

Thanks,
Dave
