Mongoose geolocation inaccurate response

this is my schema:

var onlineStatusSchema = mongoose.Schema({
    loc: {
        type: {},
        default:[]
    }
});
onlineStatusSchema.index({loc:'2d'});

and this is my query:

var query = onlineStatus.find({
     loc: {$nearSphere: [myLat,myLong], $maxDistance:10}});
query.exec(function (err,pros) {//response});

I am getting inaccurate data, i have tried changing 2d to 2dsphere also but it gives me all data which is within 10km or outside 10km

Solution

  • Try to divide the $maxDisatnce value with earth's radius ie, 6371 approx for KM.

    $maxDistance:10/6371

    This will help.
