WebAug 6, 2024 · you may want to try the other approach - turning the s2 processing off - first. It is a quick and dirty approach, may be deprecated in the future and does not resolve the underlying issue (it just reverts to a less sophisticated fallback method) but if you require just a quick plot it may do the trick – Jindra Lacko Aug 6, 2024 at 12:28 WebExercise 4.1. Straight GeoJSON lines. How does the GeoJSON format define “straight” lines between ellipsoidal coordinates (section 3.1.1)?
