I am querying a polygon, to check if a point is inside of it or not, but no results are returned. I am in the mongo shell: (MongoDB shell version: 3.2.6)
db.restPolygons.find();
{
"_id" : ObjectId("586e663175c32828be59e3a9"),
"zoneCoordinates" : {
"type" : "Polygon",
"coordinates" : [
[ 2, 0 ],
[ 6, 0 ],
[ 6, 2 ],
[ 2, 2 ],
[ 2, 0 ]
]
}
}
db.restPolygons.find({
"zoneCoordinates": {
"$geoIntersects": {
"$geometry": {
"type": "Point",
"coordinates": [3 ,1]
}
}
}
}).count();
0
Your polygon is invalid, it's missing a level of enclosing array in the coordinates field. This one should work:
> db.geo.find()
{
"_id": ObjectId("586e663175c32828be59e3a9"),
"zoneCoordinates": {
"type": "Polygon",
"coordinates": [
[
[2, 0],
[6, 0],
[6, 2],
[2, 2],
[2, 0]
]
]
}
}
> db.geo.find({
"zoneCoordinates": {
"$geoIntersects": {
"$geometry": {
"type": "Point",
"coordinates": [3 ,1]
}
}
}
}).count()
1
You can check the validity of your GeoJSON object in GeoJSONList
