Free field-data tool for Australian farmers

GDA94 to GDA2020 ISOXML Converter

Keep your existing AB lines, paddock boundaries and obstacles when changing machines, correction services or Australian datums.

Australian broadacre harvesting where saved AB lines and paddock boundaries are reused between machines
Saved guidance lines are part of the farm. Changing machinery should not mean mapping every paddock again.

Why old guidance lines may no longer match

Australia's GDA94 and GDA2020 datums describe the same land using coordinates that differ by roughly 1.8 metres. A receiver can have a perfect RTK fix and still miss an existing AB line if the new machine and the saved field data are using different datums.

That mismatch can appear after changing tractors, displays, receivers or correction providers. Re-mapping every paddock is not the only option.

What the converter does

  1. Upload your field dataLoad an ISOXML package or another supported spatial-data file from your machine or USB.
  2. Identify its datumSelect GDA94 or GDA2020 when the source file does not identify the datum itself.
  3. Clean the packageVKLink retains guidance lines, paddock boundaries and obstacles while leaving out coverage, fuel and task records.
  4. Download either datumReceive clean ISOXML packages in both GDA94 and GDA2020, ready for your next display or fresh USB.

Every coordinate is transformed

The converter does not apply a rough 1.8 metre shift to the whole farm. It processes every coordinate point using the official seven-parameter GDA94/GDA2020 coordinate-frame transformation documented in the GDA2020 Technical Manual.

This preserves the shape and location of straight AB lines, curved guidance patterns, field boundaries and mapped obstacles in the selected Australian datum.
