Hi list,
is it possible to perform the following classification in Mapserver?
I have an attribute table for polygons like this (for each zone the
percentage is given):
polygon zone1 zone2 zone3 zone4 .. zoneN
1 60 20 20 0
2 20 60 10 10
3 40 40 20 0
zone1: blue
zone2: red
zone3: green
zone4: yellow
In this situation I would want each polygon to have the color of the zone
with the highest percentage, if there is one zone that has a percentage >=
60%.
If none of the zones have a percentage >= 60%, the polygon will be
depicted with one color, and the other (second dominant zone) color as the
color for pattern hatching.
Thanks in advance for the info.
Best regards,
Bart
