Hi,

Does&nbsp;anybody&nbsp;know&nbsp;if&nbsp;we&nbsp;have&nbsp;any&nbsp;functions&nbsp;to&nbsp;detect&nbsp;spatial&nbsp;conflicts?&nbsp;For&nbsp;example,&nbsp;one&nbsp;area&nbsp;is&nbsp;overlapping&nbsp;another&nbsp;area.

Thanks,

Wilson&nbsp;Jiang

Hi&nbsp;Wison,  
To&nbsp;check&nbsp;whether&nbsp;there&nbsp;are&nbsp;other&nbsp;shapes&nbsp;in&nbsp;the&nbsp;area&nbsp;of&nbsp;another&nbsp;shape,&nbsp;I&nbsp;think&nbsp;we&nbsp;can&nbsp;check&nbsp;the&nbsp;intersection&nbsp;between&nbsp;two&nbsp;shapes.&nbsp;Here&nbsp;as&nbsp;following&nbsp;is&nbsp;the&nbsp;demo&nbsp;code:  
&nbsp;  
`BaseShape shape1 = BaseShape.CreateShapeFromWellKnownData("POLYGON((10 60,40 70,30 85, 10 60))");BaseShape shape2 = BaseShape.CreateShapeFromWellKnownData("LINESTRING(60 60, 70 70,75 60, 80 70, 85 60,95 80)");// check the conflict between shapesbool isIntersected = shape1.Intersects(shape2);`  
  
Also&nbsp;you&nbsp;can&nbsp;refer&nbsp;to&nbsp;the&nbsp;installation&nbsp;sample&nbsp;“Samples/&nbsp;QueryingFeatureLayers/&nbsp;SpatialQueryAFeatureLayer.aspx”&nbsp;for&nbsp;detail.  
&nbsp;  
Thanks,
