[mapguide-users] mapagent operation=QUERYMAPFEATURES

[Traian Stanev]

The input point is probably not *exactly* equal to the feature point and hence a point query with Intersects will not work. I would use a small rectangle query with the EnvelopeIntersects or Intersects operation. Note that by small rectangle, I don't mean a zero size rectangle, but something with width and height of say 1e-6 for example.

	Hi There,
	
	  I am having trouble selecting elements on a point layer. Query looks
	something like this :
	
	
	....&operation=QUERYMAPFEATURES&geometry=POINT(663293.447226639%205431187.3623488685)&selectionVariant=INTERSECTS...
	
	  I have tried WITHIN for the selectionvariant with no success.
	  I have also tried a polygon geometry where the Min=Max with no success.
	  Note that using a polygon geometry around a point element selects the
	element as expected.
	
	  Any idea what I am doing wrong ?
	
	Thanks
