Hi Andreas,
I have looked and looked but could not find how to use ogr2ogr to do
the operation I am interested in. Could you point me in the right
direction here as to how can ogr2ogr be used to add new fields to an
existing dbf file from another dbf file. The external dbf file from
which I need
Hi,
Thanks a lot Andreas. That JOIN was the culprit as you rightly
suggested. Once I removed the join, the performance increased

Hi Puneet,
Thanks a lot for the prompt reply. I tried using Excel 2007 and was
not able to re-save the dbf file after editing. Also, I am having DBF
files with about

Any help in this regard is greatly appreciated. Let me know if you
need any more information.

Hello Everyone,
I have programmed a GIS application using Mapserver, Google maps and

data (from the dbf file) for all features (Points) within a randomly
drawn user shape and doing some statistical operation on that data. I

By adding DEBUG 5 for your layer you don't need stopwatch but you'll get

I am trying to get my mapserver and tilecache work together but its
