Partial polygonization means building polygons only for a subset of selected centroids in polygonal layer.
  1. Before running polygonization based only on a subsample of centroids available in polygonal layer, you have to prepare and compile simple OnLayer BeforeBuildPolygons script event


begin

Globals.SetGlobalVariable('ConsiderSelectedCentroids', 1);     

end.


For additional tips how to prepare a user-defined script in Field-Map see Scripting help.



  1. Select those centroids to be considered in polygonization process
  2. Click Polygonization button



  1. Set parameters of polygonization

See Non-overlapping polygonization for details

  1. Click OK



  1. In the next message window, you will be asked to confirm that you really want to use only selected centroids. Click Use selected centroids only button.



  1. The Poly-Shape appears



  1. Go to the polygonization process in a same way, as described in Non-overlapping polygonization to get the result
