Got to try out some new Spatial techniques here, very helpful learning experience.

Fun spatial challenge!  I got to the correct answer, but I'll be interested in how others solved it!

This was a fun spatial challenge, it gave me a good refresher into spatial Alteryx functions.  Thank you, Claire, @clmc9601

I split the Counties data set into detailed regions, but in this case splitting by Regions works as well, as we are not looking into which parts of the counties are considered 'Holes' in identifying islands, as the logic for the islands has already been defined by size of less than 5 sq km.

Can actually skip the Formula tool, as the Filter is already for islands of less than 5 sq km.   I should have taken it out, ooops!

Please see my updated solution.  I took out the duplicative Formula tool, it was no need for it.

I wonder if the length of intersection of the coastline of the continent is properly calculated...
