Quick way to fill in multiple (i.e. thousands of) 'holes' in a polygon feature?

[Marty Rocks]

Hi everyone. So I've a polygon of Australia, which includes all the lakes and ponds in the country which number in the thousands. All I want to do is 'fill them in' leaving em with a solid polygon that has one single outline and no holes. Is there a quick (or at least efficient) way to do this in Mapinfo? To my eternal shame, I've been toying around with ESRI's donut hole filler tool but to no avail and was hoping for a similar tool in Mapinfo...?

Cheers everyone!

Select the polygon and go Objects -> Disaggregate, select All Objects and un-tick 'Retain Holes in Regions'

This should turn all the holes into separate polygons which you can then remove etc

Looong time before MapInfo had it as a built-in feature, I added it to the RouteWare ToolBox:

You can even get the source from the download page.

Thanks Uffe. Tim's method works but some of the datasets are enormous, causing my computer to crash. I'll give your tool a try and let you know how I get on!

Another method but less data intensive.

1) zoom into somewhere on the outer border so that you can see individual nodes.

2) with layer editable, go into node mode (CTRL-R) and click on a node.

3) Holding CTRL key, click on the same node. You have now selected every node in that outer polygon.

4) Ctrl-C (copy).

5) Make sure the layer you want is editable and paste.

6) The new object is a polyline. You can convert it to region via the objects menu.

I missed this somehow Eric, thanks for that, that worked perfectly!
