<PolygonGeo variable>.Difference (Function) In french: <Variable PolygoneGéo>.Différence Returns a geometry representing the difference between a geographic polygon and another geometry. Syntax
<Result> = <Geometry A>.Difference(<Geometry B>)
<Result>: Variable of type MultiPoint2D, MultiPointGeo, MultiLinestring2D, MultiLinestringGeo, MultiPolygon2D or MultiPolygonGeo Difference. This geometry contains a collection of geometries of a given type: If the difference between two geometries consists of a single element, the collection will contain a single element.
If the difference is empty (for example, by calculating the difference between a geometry and itself), the collection will be empty.
If the result of the difference is disjoint (e.g. by splitting a polygon into two), the collection will contain several elements. <Geometry A>: PolygonGeo variable Name of the PolygonGeo variable to be used. <Geometry B>: Variable containing spatial data Geometry to be compared against Geometry A. This geometry can correspond to one of the following variable types: Business / UI classification: Business Logic
