This is a simple example to create a TGIS_ShortestPath object.

var
  rtrObj : TGIS_ShortestPath ;
  layerSrc : TGIS_LayerVector ;
  GIS: TGIS_ViewerWnd;
begin
  // let's get a source layer
  layerSrc := TGIS_LayerVector( TGIS_LayerSHP( GIS.Items[0] ) ) ;
  if not Assigned( layerSrc ) then exit ;
 
  // create a TGIS_ShortestPath object and attatch data from the source layer
  rtrObj := TGIS_ShortestPath.Create( GIS ) ;
  rtrObj.LoadTheData( layerSrc ) ;
  rtrObj.RoadName := 'NAME';
end ;
