$minDistance

$minDistance

Filters the results of a geospatial $near or $nearSphere query to those documents that are at least the specified distance from the center point.

If $near or $nearSphere query specifies the center point as a GeoJSON point, specify the distance as a non-negative number in meters.

If $nearSphere query specifies the center point as legacy coordinate pair, specify the distance as a non-negative number in radians. $near can only use the 2dsphere index if the query specifies the center point as a GeoJSON point.

Important

If specifying latitude and longitude coordinates, list the longitude first and then latitude:

  • Valid longitude values are between -180 and 180, both inclusive.
  • Valid latitude values are between -90 and 90, both inclusive.

Consider a collection places that has a 2dsphere index.

The following example returns documents that are at least 1000 meters from and at most 5000 meters from the specified GeoJSON point, sorted from nearest to farthest:

db.places.find(
{
location:
{ $near :
{
$geometry: { type: "Point", coordinates: [ -73.9667, 40.78 ] },
$minDistance: 1000,
$maxDistance: 5000
}
}
}
)

Consider a collection places that contains documents with a location field and has a 2dsphere index.

Then, the following example returns whose location is at least 1000 meters from and at most 5000 meters from the specified point, ordered from nearest to farthest:

db.places.find(
{
location: {
$nearSphere: {
$geometry: {
type : "Point",
coordinates : [ -73.9667, 40.78 ]
},
$minDistance: 1000,
$maxDistance: 5000
}
}
}
)

For an example that specifies the center point as legacy coordinate pair, see $nearSphere
