[mapserver-users] Rendering overlapping data

[Fawcett, David (MPCA)]

Take a look at symbol TYPE HATCH here:  http://mapserver.org/mapfile/symbol.html  I am sorry that I don't have an example handy for you.

You can also see how to create hatch symbols using pixmaps for areas here:

Subject: [mapserver-users] Rendering overlapping data

Dear list members

We would like to visualize a layer with data, where polygons with 
different classes may overlap. Using transparency, "new" colors are 
introduced, e.g. if I overlap a blue and a red polygon I get an violet one.

Is there a way to show overlapping polygons in stripes with cycling 
colors, or as a checker board? How do people handle this?

Regards,

Peter
