Using H3-py's h3_to_geo_boundary a WKT linestring (via shapley polygons) can be generated.

When later visualizing the hexagons, why are they distorted? How can this be fixed?

enter image description here

To my best knowledge, H3 works in EPSG:4326. As you can see on the plot, the base-map coordinate system is also set to 4326. And QGIS also interprets the CSV of WKT strings as 4326.

Why do I see the distortion? How can it be fixed?

  • what projection did the hexagons come with or what did you set the projection of the hexagons to? – Ian Turton Nov 25 '19 at 9:13
  • I kept the default output of H3. When loading it from QGIS it was interpreted as 4326. – Georg Heiler Nov 25 '19 at 9:15
