Polygons are not filling the shape of the Antarctic continent #189

Open patriklaszlo opened 5 months ago

Describe the bug In the Hexed Country Polygons example, the Antarctic polygons are not properly filling the shape of the continent.

Expected behavior Antarctic to be made up of polygons the same way rest of the continents are.

@patriklaszlo thanks for reaching out.

This is related to the issue in H3 on the difficulty to handle polygons which include poles. Such is the special case with Antarctica. The issue is here: https://github.com/uber/h3-py/issues/285

The recommended approach is to slice up that specific polygon in slices like a pizza. That's a pre-processing that needs to be performed on the input geojson. I haven't had the chance to do that to see if it fixes the issue, but I suppose it should.
