I'm aware of this challenge but the polygon checker cannot handel the conditions of the challenge.
The checker can do the first 15 islands, no problem but the second list 4 out of 8 islands is a problem. The checker can be set that you must have 19 island but this does not mean that the first 15 are in the result..

So at the moment it is not possible to use the polygon checker unless the CO alters his conditions

... or if someone improves the script.

So technically it's possible, but it might be hard to find someone who wants to spend time on it.

I've already looked to this challenge some time ago, but I've found that no one has found it yet. So I've see that the checker is not need. However, now, as there is the request, I can modify my checker for this challenge. Once I'll found a bit of time, I'll do it.

Do the polygons exist for this one?

The polygon exists only on OSM. I've tried to extract something, but hopelessly there are a lot of work not only on extract polygons, but also on modify the checker to check multiply polygons.
The problem is, that the polygon from OSM is not simple polygon, but a set of polygons (one object, in this case the isle, can be defined by 2 or more distinct polygons) and also by set of excluded polygons (a hole inside the polygon).
It's impossible to verify by hand the polygons exported by osm, so the checker should accept exactly this complex format.
The procedure for extract polygon from OSM has few parameters for simplify the polygons (raw polygons has about milion points), so you should find a compromise.

here is the polygon creator:
http://polygons.openstreetmap.fr/index.py

If I use the same setup for the polygons as for the script "Generic Poly Checker with open polygon support(by sloth96)" the json file will only take me a couple of hours.

sloth96 can this script be altered for the challenge?

I believe it can be altered. I just need to divide the list and run two checks.

A couple of hours sound like much work.

If I get the time I'll work on it tonight but it will take a couple of days before it is uploaded into the system

Howdy,

Here is a checker for this one.

I do not have an example of anyone who has completed it. Running it with janko42 the co only has a partial completion.

The polygons look spot on.

Feedback appreciated.

Wow. Great work!
Complimenti.

The heavy lifting prize goes to vogelbird for the polygons. The rest is window dressing.
