I see that Jeff has given some good debugging techniques. A
method I've used is to make an Identify Template showing the
"COUCHE" attribute value and any unique id value then doing an
Identify on the feature (the value shown may give some insight into
why it is being rendered as a railway). Another method is to use
an output format of GML and output the area using shp2img then
examine the output values.<br>
