[mapserver-users] Clipping out unprojectable area?

[paalkr]

Hi!

I'm trying to achieve the same thing, but I need some hints on how to
incorporate the spatial filter in the DATA statement. This is a snippet from
my mapfile

      DATA "geometri from general.country USING UNIQUE ogc_fid USING
SRID=4326"

and this is the spatial filter i try to apply

      ST_Intersection(geometri,GeomFromText('POLYGON((12 0,18 0,18 84,12
84,12 0))',4326))

but I don't manage build the right the DATA statement!

Can someone please help with the DATA statement?

Regards,
Pål Kristensen
