That is a fairly toothless criterion because you will very often be able
to achive this simply by mapping the coastline in more detail (making
A more robust and tighter criterion would be that the length of the
non-water part of the boundary needs to be shorter than the square root
of its area. Geometrically this limit is equivalent to a square shaped
peninsula connected at one of its sides. Ultimately any such criterion
is an arbitrary limit of course.
Practical examples of things frequently called peninsulas that exceed
this limit are the Balkan Peninsula:
and the Indian subcontinent:
But i think if you really want natural=peninsula to be meaningful
geometrically you need to go at least to this limit.
