How to fill "holes" in Raster / Polygon?

[JosuaInauen]

Is there a way to automatically fill such holes which aren't really holes?

Thx in advance!

We use the Fill tool. Spatial Analyst Tools > Hydrology > Fill

For a vector, a handy trick is to use the Union geoprocessing tool with only one input and the 'allow gaps' option disabled.  It is however a bit temperamental.

You could use the Con tool

How would this be implemented Steve? is there some way to look for containment?

Or for the case being shown...

• Expand the raster (maybe by 2 cells) the buffer equivalent for rasters, then a
• Shrink the result of the above by the same amount

This Expand/Shrink sequence can be used to get rid of inner inclusions and exterior fiddly-bits as well.  You can repeat the above overwriting the temporary grids,  It is an alternative to pointing at the screen and saying get rid of that bit
