Hi Andrey, I am aware that this is not ogr2ogr solution, but you can watch my lecture on this kind of problem and procedure to avoid this problem in QGIS - and then maybe you can apply the same procedure/logic using only ogr2ogr.
See this video, you can skip to around 45 minutes. https://www.youtube.com/watch?v=5M-Q0AinuiY&t=2702s uto, 14. lis 2025. u 22:02 Andrey VI via gdal-dev <[email protected]> napisao je: > Unfortunately, the result is still incorrect. > The empty areas are still here around 88-89°N and some polygons are still > broken (for example at -67°W, 76°N): > Example <https://i.ibb.co/CpQGWdpk/Example.png>. > These polygons turned out to be hidden under others, although in the > original data all polygons are adjacent but not overlapping.
