Geospatial Data

If a collection contains a 2d or 2dsphere geospatial index, BI Connector maps the indexed field into an array of numeric longitude-latitude coordinates.

Example

Given the following collection:

db.points.createIndex( { pos : "2dsphere" } )
db.points.insertOne({
    pos : { type: "Point", coordinates: [ -73.97, 40.77 ] },
    name: "Central Park",
    category : "Parks"
})

BI Connector generates the following schema:

schema:
- db: test
  tables:
  - table: points
    collection: points
    pipeline: []
    columns:
    - Name: _id
      MongoType: bson.ObjectId
      SqlName: _id
      SqlType: varchar
    - Name: category
      MongoType: string
      SqlName: category
      SqlType: varchar
    - Name: name
      MongoType: string
      SqlName: name
      SqlType: varchar
    - Name: pos.coordinates
      MongoType: geo.2darray
      SqlName: pos.coordinates
      SqlType: numeric[]

BI Connector does not recognize geospatial fields when reading from a view.
