KML anyone

[Hal Eden]

hi, i've been hacking around for some demos here and came up with a  
version that will generate KML for polygons (based on the GML code),  
which allows me to specify a WFS url in google earth and overlay  
shapes onto the terrain.

it's pretty quick and dirty (for example it is hardwired to use  
either ELEVATION or ROOFELEV attributes in our shapefiles to  
determine the z-coordinate), but it shows the concept.

my questions:

	is this useful for anyone else?
	how might it fit into the bigger picture? is there any movement toward
		3D data from mapserver?
	how might extension into WFS options be best approached? (e.g., if i
		 want to specify in the query what attribute to use for the z- 
coordinate?)

any feedback welcome
