Geospatial features in MongoDB
Geospatial features in MongoDB are designed to support the creation of location-aware applications and facilitate location-based queries, catering to a diverse range of users. Through its specialized indexes and operators, MongoDB can efficiently manage geographical data, which makes it suitable for a wide range of applications, such as maps and location searching.

GeoJSON objects are of three types:
Point: Represents a single point in space with longitude and latitude coordinatesLineString: A series of two or more points that...
