Selecting FDO Features inside a given boundary (Polygon)

By Partha Sarkar

Another question I have come across: How do I select FDO Features inside a given boundary (polygon) using API?

 

Following C# code snippet demonstrates usage of MgFeatureQueryOptions.SetFilter() to select features inside a given boundary (polygon) :

 

  //spatial relationship inside a basic filter

  MgFeatureQueryOptions query = new MgFeatureQueryOptions();

  query.SetFilter("Geometry INTERSECTS GeomFromText('POLYGON ((135450.170691914 176714.481673732, 136292.021019111 176121.027356537, 135961.299875354 175651.879698467, 135119.449548157 176245.334015662, 135450.170691914 176714.481673732))') ");

 

  //Get the features

  MgResourceIdentifier resId = new MgResourceIdentifier(fsId);

  MgFeatureReader ftrRdr = fs.SelectFeatures(resId, className, query);

 

Hope this is useful to you!
