    Description

      It would be nice for GEO queries to find stored Big Polygon documents, after the 2.8 release that allows $geoWithin and $geoIntersect queries that reference Big Polygon GeoJson objects.

      Big Polygon means a polygon with area larger than one hemisphere.

      The following mongo shell script would work with the feature addition.

      // current CRS
      var CRS = {};
      CRS.type = 'name';
      CRS.properties = {};
      CRS.properties.name = 'urn:mongodb:strictwindingcrs:EPSG:4326';
       
      // Big Polygon covering both poles
      // this document will NOT be found in the 2.8 release
      // b/c this feature does not recognize stored big polygon objects
      var bigPoly = {};
      bigPoly.geo = {};
      bigPoly.name = 'big polygon/rectangle covering both poles';
      bigPoly.geo.type = 'Polygon';
      bigPoly.geo.crs = CRS;
      bigPoly.geo.coordinates = [
                    [ [ -130.0, 89.0 ], [ -120.0, 89.0 ], [ -120.0, -89.0 ], [ -130.0, -89.0 ], [ -130.0, 89.0 ] ]
                  ];
      db.foo.insert(bigPoly);
       
       
       
       
      // Triangle around Shenzhen, China
      var shenzhenPoly = {};
      shenzhenPoly.type = 'Polygon';
      shenzhenPoly.coordinates = [
                                   [
                                     [ 114.0834046, 22.6648202 ],
                                     [ 114.2736054, 22.4047911 ],
                                     [ 113.8293457, 22.3819359 ],
                                     [ 114.0834046, 22.6648202 ]
                                   ]
                                 ];
      shenzhenPoly.crs = CRS;
      db.foo.find({geo: {$geoWithin: {$geometry: shenzhenPoly}}});
