mongodb中的地理空间数据

Question

How to store Geo-spatial data in Mongodb? How MongoDB supports or stores Geo-spatial data compared to normal data? How to command/suggest Mongodb to consider the inputted data(JSON Object) as Geo-spatial data? What are the various features/support provided by MongoDB for Geo-Spatial data?

Please help me with good documentation/Reference link as I am new to MongoDb and the concepts of Geo-spatial data.

Thanks a lot in advance.

I'd start with the MongoDB docs: https://docs.mongodb.com/manual/geospatial-queries/

And continue with my webinar: https://www.slideshare.net/mongodb/getting-started-with-geospatial-data-in-mongodb

MongoDB treats geo data like other data since the Document model permits arbitrarily complex shapes. In general, a geo field is a substructure with a type fields and a coordinates field, eg

{
  name: "Buzz",
  location: { type: "Polygon", coordinates: [ array of rings, each ring is an array of points, and a point is small array of [lon,lat] ]}

}
