      I have a large GeoJSON collection with some polygons that crosses the date line. Because of that these polygons, I am not able to create a 2dsphere index on the collection.

      Different GIS tools handle this use case differently. Some opts to support longitude that < -180 and > 180 to represent shapes that cross the merdian the short way, instead of the long way (across the other side of the globe).

      MongoDB as a database system that stores these data, should be generic enough to handle this use case.
