Wouldn't the spatial filter be more appropriate, since the clipper base actually alters ('clips') those polygons along the edge if they are not perfectly congruant with the base polygon.

Hi Richard,

You could try the clipper transformer. The clipper would be your
country boundary and the clipee would be the polygon input file. The
desired output would be from the inside and clipped inside options on
the transformer, which grabs all the features that touch the boundary of
your country polygon, or those that fall within. For further
information about this transformer look at the help option which is
thorough in its explanation.

Hope that helps a little.

Subject: [fme] Filtering Polygons

I have an input file of polygons. I require a filtered set of those
polygons based on our county boundary (available as a separate polygon).
The result should include all those that are fully or partly with the
county boundary.

I can't figure out which transform to use. Can anyone help with this
(simple) task.

Thanks
