    read

    read

    This function will read an RDD layer based on a query.

    K

    Type of RDD Key (ex: SpatialKey)

    V

    Type of RDD Value (ex: Tile or MultibandTile )

    M

    Type of Metadata associated with the RDD[(K,V)]

    id

    The ID of the layer to be read

    numPartitions
