Line Labels (multiple Labels)

[Stephen Woodbridge]

I have asked about this feature in the past. It would be a very nice 
feature to have, but it is not available in mapserver yet unless you 
want to code it up :) maporama does it and it looks very nice.

I think it would be great if mapserver supported a more abstract label 
positioning grammar like:

LABEL
   LABELITEM <field>
   ...
   LOCATION
     POSITION ...
     PERCENT_ALONG <float>
     SIDE [LEFT|RIGHT|CENTER|INSIDE|OUTSIDE]
     OFFSET [X|Y|NORMAL] <float>
   END
END

Then you could attach multiple label blocks to a layer to generate the 
labels you want. Moving LABELITEM into the LABEL block allows each block 
too have its on item field.

This could also be used to display labels along polygon boundaries using 
INSIDE|OUTSIDE for things like administrative boundaries.
