Label collision trouble

[Bruce Cheney]

David,

That was just the solution I needed.  Exact label placement is much more
usable. Thanks.


Bruce

If your data is pretty static, it might be doing it this way.  You could
create a point shapefile to use as label points.  You would then create
a layer of type ANNOTATION to place your labels.  This is a lot more
work up front, but it guarantees that the labels will be exactly where
you want them.

Thanks for your help Dylan.  That is certainly helping.  I removed
FORCE, dropped my SYMBOLSCALE, and removed PARTIALS.  The collisions are
not happening now (probably because of FORCE being removed).  I would
like PARTIALS to stay on but they are messy - crossing boundaries, etc.
Is there some way to force labels in a polygon to stay in the same
position relative to the center - I don't want them moving around every
time a user pans or zooms in?

Thanks again.

Bruce,

What happens if you remove FORCE ON (should be FORCE TRUE), or change it
to FORCE FALSE?  You might also try POSITION AUTO.  With so many labels
you'll really have to finesse POSITION, FORCE, LABELMINSCALE,
LABELMAXSCALE, PARTIALS, and possibly other parameters just right for
each layer.
