[Mapserver-users] shpxy

[Paul Spencer]

Hi,

I'm using the [shpxy xf="," transform] in a template to create imagemaps 
... the imagemap  onmouseover/onmouseout dynamically positions a dhtml 
div element over the feature in the map.  This works exceptionally well 
for points but it doesn't work for polygons.

Is there anything I can use in a template to get a centroid value for a 
polygon (rather than all the points)?

Also, has anyone tried to do this for lines?  I'm using mapscript and 
generating the template dynamically based the type of a selected layer. 
  Right now my approach is to get the points that make up lines and then 
create polygons by buffering the lines ... this is obviously quite a lot 
of work in php :)

Cheers,

Paul
