根因分析
在具有 2dsphere 索引的集合中,文档包含格式错误的 GeoJSON 对象,缺少必需字段(type/coordinates),或坐标值无效(例如纬度超出 ±90 或经度超出 ±180)。
English
Documents in a collection with a 2dsphere index contain GeoJSON objects that are malformed, missing required fields (type/coordinates), or have invalid coordinate values (e.g., latitude outside ±90 or longitude outside ±180).

-
使用脚本查找无效文档:`db.collection.find({ "loc": { $not: { $type: "object" } } })` 或检查缺失字段:`db.collection.find({ "loc.type": { $exists: false } })`。然后更新或删除它们。 -
使用 `db.collection.aggregate([{ $addFields: { loc: { $cond: { if: { $eq: [{ $type: "$loc" }, "array"] }, then: { type: "Point", coordinates: "$loc" }, else: "$loc" } } } }, { $out: "collection" }])` 将旧式数组转换为 GeoJSON。 -
如果坐标超出范围,进行钳制:`db.collection.updateMany({}, [{ $set: { "loc.coordinates.0": { $min: [ { $max: [ "$loc.coordinates.0", -180 ] }, 180 ] } } }])`(对纬度重复)。
无效尝试
常见但无效的做法:
-
95% 失败
The invalid documents remain in the collection and will cause the same error when the index is rebuilt or when querying.
-
80% 失败
2dsphere indexes only support GeoJSON format; legacy pairs require a 2d index, not 2dsphere.
-
60% 失败
Human error can introduce additional malformed data; a scripted approach is safer.
