A method for reporting of positioning data in a communication network comprises obtaining () of positioning data comprising a definition of a polygon in a lateral plane with information of altitude associated to each polygon corner. The method further comprises approximating () the polygon with an ellipsoid point having altitude and uncertainty ellipsoid and reporting () of the ellipsoid point having altitude and uncertainty ellipsoid over an interface of the communication network as a representation of the positioning data. A node in a communication network comprises a report converter arranged for obtaining positioning data and approximating a polygon with an ellipsoid point having altitude and uncertainty ellipsoid.
