[ka-Map-users] Repeated labels on a polygon layer

[David Badke]

I have a map with two polygon layers. Two other annotation layers label 
the polygons. This all works, except that the labels repeat - each 
polygon has the same label, in different places, two or more times. In 
some cases one of the repeated labels isn't even on the polygon, and 
none of the labels are where I wanted them (POSITION UL). I have tried 
changing the annotation layers to point or polygon layers - doesn't 
help. The layer data is all in shapefiles (except the base layer).

So is this a ka-Map problem, a MapServer problem, a data problem, my 
problem, or what? Anyone have any idea how to make it stop doing this?

You can see an example at

         
http://vihistory-dev.uvic.ca/maps/htdocs/index.php?map=vicstreet1902

Zoom in to 50% (the middle block in the zoom widget).

The  map file for this is:
