      Description

      The following CRS (on uDig projections database) do not have the necessary TOWGS84 parameters:

      Lisbon (Lisbon) (4803) - TOWGS84[-304.046,-60.576,103.64,0,0,0,0],AUTHORITY["EPSG","6803"]

      Lisbon (Lisbon) (deg) = Lisbon (Lisbon) (4803)

      Lisbon (Lisbon) / Portuguese Grid (20791) - TOWGS84[-304.046,-60.576,103.64,0,0,0,0],AUTHORITY["EPSG","6803"]

      Lisbon (Lisbon) / Portuguese National Grid (20190) - TOWGS84[-304.046,-60.576,103.64,0,0,0,0],AUTHORITY["EPSG","6803"]

      This cause a displacement of 200-300 meters in Portugal mainland.

      It is also necessary to provide the equivalence between the following ESRI projections:

      ESRI:102164: "Lisboa Hayford Gauss IGeoE" is equivalent to EPSG:20790

      ESRI:102165: "Lisboa Hayford Gauss IPCC" is equivalent to EPSG:20791

      ESRI:104106: "GCS Datum Lisboa Hayford" is equivalent to EPSG:4207

      ESRI:102161: "Datum 73 Hayford Gauss IPCC" is equivalent to EPSG:27493

      ESRI: "GCS_Datum_73" is equivalent to EPSG:4274: Datum 73
