<p>A question, is this database only intended for very large polygons, or also rather small?</p>
<p>From my mapping perspective here in Sweden fuzzy polygons exist down to say ~1 km size (generally speaking names of hills, valleys, peninsulas etc). In fact the most I run into is in the 2 - 10 km size. I also come across many bays and straits of similar sizes, those can be defined (and rendered) in OSM already today, but I now understand that many don't like that they exist, so maybe those should be managed in this type of separate database too?</p>

<div>So you could license this as CC0, but it does not mean that other limitations are</div>
<div>not applying (limited extraction of just some shapes from OpenStreetMap may</div>

<div>For the avoidance of doubt, there is currently no data from OpenStreetMap in OpenGeographyRegions, and there will not be in the future, so that the data can be used without limitations. My intention is using it together with OSM data, but of course you can use it with whichever data you want. </div>
</div>
<div> </div>
<div>These regions, although it would be legally possible, should not be imported in OSM either, because they are in medium and large scale resolution and not suitable by their nature (not well defined on small scales, fuzzy boundaries, etc.).</div>
