      In the following example, I have some stored polygons located over the Baltic sea (between Sweden and Finland). Whenever I draw a polygon over the area where the polygons lie, they are correctly detected, namely all 609 objects are found. (see query and Screenshot_1)

      db.geojsons.find({
        location: {
          $geoIntersects: {
            $geometry: {
              type: "Polygon",
              coordinates: [
                [ [17.314453, 61.648162], [17.314453, 64.434892], [26.542969, 64.434892], [26.542969, 61.648162], [17.314453, 61.648162], ],
              ],
            },
          },
        },
      });
      

      However, the strange behavior occurs when submitting a wider query polygon a little bit below (see Screenshot 2 and 3 with the corresponding queries).

      db.geojsons.find({
        location: {
          $geoIntersects: {
            $geometry: {
              type: "Polygon",
              coordinates: [
                [ [-4.482422, 61.93895], [46.318359, 61.93895], [46.318359, 58.585436], [-4.482422, 58.585436], [-4.482422, 61.93895], ],
              ],
            },
          },
        },
      });
      

      As well as:

      db.geojsons.find({
        location: {
          $geoIntersects: {
            $geometry: {
              type: "Polygon",
              coordinates: [
                [ [-4.482422, 61.93895], [36.318359, 61.93895], [36.318359, 58.585436], [-4.482422, 58.585436], [-4.482422, 61.93895], ],
              ],
            },
          },
        },
      });
      

       

      Hereby, I also attach three example GeoJSONs that I use:

      Hello everyone,

      I am currently working on a project, where I store polygons using the native GeoJSON format and then perform geospatial queries to locate these based on both $geoIntersects and $geoWithin operator. Indeed, everything seemed to be working fine.

      However, yesterday I discovered a strange behavior, which I am going to reproduce with an example.
