Hi There,
maybe using OGR join to achieve that could be a solution. Check the
following post:
http://lists.osgeo.org/pipermail/mapserver-users/2004-November/002149.html
On a MapServer layer you can do something like:
LAYER
CONNECTIONTYPE OGR
CONNECTION "/test/my_shape_file.shp"
DATA "SELECT ..."
...
END

Hi,
I am using mapserver to generate map overlays for google (using
tiles). I was wondering if there is a way in which I can color code
the map based on external data (data not available in the dbf file). I
was able to join the external data and display to the user when a
click event happened but could not figure out a way in which mapserver
can color code using expressions and classes. Is the only way to this
is combining the external data with the existing dbf file?
Thanks,
Varun
