[mapserver-users] Get the nearest layer with mapscript...

[Fawcett, David]

Paul, 
 
I would guess that this really is about the client-side map interface and not about MapServer.  Does your interface only allow them to click/select the topmost layer?  Do you pick which layer is selectable?  Do you let them pick which layer is selectable?  Is it random?  
 
Tells us more about the client-side app.
 
David.

	Thanks Pano...
	But It´s not that simple...
	What I need is figure out what LAYER was clicked...

		Probably don't understand what exactly you are trying to achieve here but it is not as simple as map.getLayer(0) to get the topmost layer? And once you have the layer object use one of the query function to select the record? E.g.  myLayerObj.queryByPoint ?

		Hello guys...
		I have several layers (lines, points, poly) ...
		I´m developing a measure tool... User can click on map and I have to select that layer to calculate de Area with postgis...
		
		

		I´m trying to do that WITHOUT using "LAYER ACTIVE SYSTEM"...
		
		

		Is That possible using mapscript? How Can I find the nearest and toppest layer ?
		
		Thanks!
		
		Paul
