Re: [mapserver-users] Keeping labels clear of a specific path

[thomas bonfort]

There is no such functionality explicitly baked into MapServer as far
as I know. You should however be able to force the labelcache to avoid
intersecting labels like this, if you are not too worried about the
performance overhead (YMMV, you probably would want to evaluate the
overhead). I have not tested this.

layer
  name "trails"
  class
   style
#trail style
   end
   label
text "[trail_name]"
angle follow
size 9
color 0 0 0
priority 10
   end
   label
#force empty characters everywhere else on the line segment
priority 9 #less than the actual trail label, but more than the
labels from other layers
text " "
angle auto
repeatdistance 1
size 9
color 0 0 0
   end
 end
end

This is a rather ugly hack. You can contact me directly if you would
like to fund the implementation of native geometry avoidance for
labels.

[mapserver-users] Keeping labels clear of a specific path

[Matt McClelland]

Hi All

I am using mapserver 7 to make maps for a hiking website.
I am wanting to keep labels from covering the main hiking path for each map.

Labels such at the park name, waypoint names etc tend to sit over the main
track and at times hide the intersections.

I am using a map file and WMS requests to make the maps

Is there a way to kindly ask mapserver to create a label buffer about a
particular line feature? (so that no labels are drawn over that line)

thanks

Matt  :)
