Hi Mifan Thats a good suggestion but then the features will be hidden behind, and the user will not have any idea what are the possible features we support till he draws the polygons.
According to my understanding "crossing" does not make since for polygons and it only works with lines and polylines and "approaching" make sense only with points. Why don't we have types of queries listed by default, then on the next step we can have an option to pick an existing object or draw another and this way we can have multiple queries can be written for same spacial object. We have to work on the implementation details though WDYT?
