Store a city, a country or even a planet in your DB

Since MongoDB 1.8 a spherical model is also supported:



db.cities.find( { location: { *$nearSphere*: [ -0.088, 51.489 ] } } );



db.runCommand( { geoNear: 'cities', near: [ -0.088, 51.489 ], *spherical: true* } );

• Location needs to be: longitude, latitude in a field.

• For 50°N and 13°E:

• [13, -50]

• { lon : 13, lat : -50 }

• { lat : -50, lon : 13 }
