Level of expertise required for this Chapter: Advanced; general Map Maker training
If you have a polygon with ‘holes’, which you can not easily ‘fill’, for example with the Join-tool from the toolbar left, you have to run the following process:
1. With the Polygon-tool from the toolbar left, define a polygon around the ‘hole’, and give it the same display label as the main polygon (in this example: 17)
2. The result should look like this:
3. With the Select-tool from the toolbar left you select the main polygon and the new polygon:
The Selection Manager should show the same display labels (2 column).
4. In the Selection Manager window: Actions > Polygon manipulation > Join adjacent polygons of the same display label > (If a warning message of overwriting appears: Yes)
5. You might have to run the previous process (step 4) again, to have the result below.
6. The result should like this:
Note: If there are more units with different labels: Selection Manager > Actions > IDs and labels > Amend labels and IDs > Amend labels and IDs window: Set all display labels to: Enter the most appropriate code for the label (here: 68) > OK
