The Australian NTv2 Grid Conversion module and command line script enables conversions between AGD66/AGD84 and GDA94 coordinates using national grid files. It is intended as a partial replacement of the GDAit transformation software provided by The Office of Surveyor-General Victoria. National grid files obtained from the ANZLIC Committee on Surveying & Mapping are bundled with this application. If you find any issues, or re-use the code for your own projects, please take the time to send a note and let us know how it works for you. Python code is available on pypi, or via pip install australian-ntv2-grid-conversion. Source code is available from bitbucket with some documentation.
