Now say I have the extents with me out of which I created and envelope How do I get the features only within an envelope Here is the sample code FeatureLayer f="http://gis.dev.fmh.com/ArcGISWEB/rest/services/OracleData/ORACLE_BaseLayers_Mapping/0"; f.where="1=0" //no features .......................... ......................... Envelope env = new Envelope(); env.XMin = double.Parse(unitExtents[0].ToString()); env.YMin = double.Parse(unitExtents[1].ToString()); env.XMax = double.Parse(unitExtents[2].ToString()); env.YMax = double.Parse(unitExtents[3].ToString()); //now I want to get the features only within the envelope. I tried like this but know it is not right. f.where="1=1"; f.Geometry=env;
You will find however that there will be cases when Intersects() will return true even if the geometries are not touching. For example, the screenshot where green box is my envelope. It is found to intersect with all 3 geometry.Extents (point, line, area) when my real interest is only the point. For this case, you might need to write an extension that checks for all vertices intersecting the envelope.
