Madrid to ED50 Polynomial – Global Mapper

The Madrid to ED50 Polynomial transformation method allows for transformation of coordinates between the Madrid 1870 datum and the ED50 datum.

For a detailed reference on the Madrid to ED50 Polynomial transformation, refer to 2.3.1.3 "Polynomial transformation for Spain" in the EPSG Surveying and Positioning Guidance Note Number 7, part 2: http://www.epsg.org/guides/G7-2.html

NOTE OF CAUTION: This datum shift has been computed for a specific area of use and specific datums. The base Geodetic Datasource contains the standard datum transformations using this method. Creating new transformations using this method or using the transformation for data outside of the pre-determined envelopes may cause unreliable results.

The "MadridToED50Polynomial" DatumShift has the following Parameters:

Parameter Name	Type
A0	Double
A1	Double
A3	Double
B00	Double
B0	Double
B1	Double
B2	Double
B3	Double
