Introduction To Geospatial Queries In Mongodb

What Is Geospatial?

What Are Geospatial Queries?

Shapes In Geospatial Queries

1. Point → A single position
2. LineString → A series of points connected by straight lines
3. Polygon → A closed area defined by multiple points
4. MultiPoint, MultiLineString, and MultiPolygon→Collections of points, line strings, and polygons, respectively
5. GeometryCollection → A collection of different geometric types

Location Document Collection

Creating An Index

db.locations.createIndex({ location: "2dsphere" });

Geospatial Query

db.locations.find({
  location: {
    $near: {
      $geometry: {
        type: "Point",
        coordinates: [73.8567, 18.5204]
      },
      $maxDistance: 500  // Distance in meters
    }
  }
});
