So if your map's units are meters, your height and width should be 30. But if for example your map's coordinate system is WGS84, than your units are degrees and not meters. You should use a much smaller value than 30 to approximate 30 meters (something like 0.0003).</SPAN></BODY></HTML> Tue, 06 Sep 2011 13:37:59 GMT CiprianLazar 2011-09-06T13:37:59Z Finding Features within distance (meter) in FeatureLayer https://community.esri.com/t5/arcgis-for-windows-mobile-questions/finding-features-within-distance-meter-in/m-p/385774#M1656 <HTML><HEAD></HEAD><BODY><SPAN>I am working on ArcMobile API (C#) and I want to get all features with in 30 meter distance of point after creating a point object on MAP.</SPAN><BR /><BR /><SPAN>What I am doing is creating </SPAN><BR /><SPAN>Envelope(CoordinateCentre,hieght,width)</SPAN><BR /><SPAN>then </SPAN><BR /><SPAN>CreatingQueryFilter based on that Envelope with GeometricRelationShipType.Intersects</SPAN><BR /><SPAN>Then passsing this queryfilter to FeatureLayer.</SPAN><BR /><BR /><SPAN>It's not working...!
