4.2.5.5 GetIntersectingPolygonAreas

Prototype:

function GetIntersectingPolygonAreas(const SearchPolygonLayerName: string; const SearchPolygonID: integer): TMultivariantListWrapper;

Description:

The GetIntersectingPolygonsAreas is the extended version of FindIntersectingPolygons. This function returns list of IDs of polygons overlayed by selected polygon together with the area of overlay.  

Syntax:

variable := Layer.GetIntercectingPolygonsAreas(SearchPolygonLayerName, SearchPolygonID);

Part

Description

variable

A variable declared as an instance of TMultivariantListWrapper

Layer

A reference to a Field-Map layer as defined in Field-Map Project Manager

SearchPolygonLayerName

A reference to a polygonal layer where the object for which intersecting polygons should be found is located

SearchPolygonID

An identification of a reference polygons for which intersecting polygons should be found

Return value:

a multivariate list of IDs of intersecting polygons (1st column) with areas of overlay (2nd column)

Note:

For Field-Map ver. 14 this function returns a string attribute containing IDs of intersecting lines with specific areas delimited with the "|" sign (e.g., 123=23.4|34=0.01)
