Advanced Merge Wizard

Merges two polygon data sets. The result does not contain overlaps

Inputs:

• Base layer - a polygon layer that will keep all attribute fields
• Merge layer - a polygon layer that will be merged to the Base layer.
• Priority of the Merge layer as described below
  • Priority of  "-1" (Erase) - the polygons from the Base layer are erased with the polygons of the Merge layer
  • Priority of "0" (Low) -  only the polygons (or portions of them) from the Merge layer that do not overlap with these of the Base layer are added to the new layer
  • Priority of "1" (Standard) - Creates intersections where the polygons from the Merge layer  intersect these from the base layer. The intersection polygons carry the attributes of the corresponding polygons from both layers
  • Priority of "2" (High) - The polygons from the Merge layer are entirely preserved. Only these polygons (or portions of them) from the base layer that do not overlap with the polygons from the Merge layer are added to the output.

Outputs:

• New  Polygon feature class
  • No overlaps present. The polygons from the Base and the Merge layers are overlaid depending the priority of the Merge layer
  • All the attributes of the Base layer are preserved
  • Only the attributes in fields with the same name and type as these from the Base layer are preserved for the features from the Merge layer. Exception makes priority of   "1" which copies the attributes from the merge layer as well.
  • Base layer always have a Priority of "1"

Examples:

Input Layers		Base layer table
		Merge layer table
Result: Priority of "-1" (Erase)		Result table
Result: Priority of "0" (Low)		Result table
Result: Priority of "1" (Standard)		Result table
Result: Priority of "2" (High)		Result table
