How can I set the orientation and origin in a DFS2 project by extracting this information from a GeoTIFF?

[elche6]

I am working on a Python Jupyter Notebook script to convert a GeoTIFF file into a DFS2 format. While the script is functioning overall, I have not yet been able to correctly write the geographical information extracted from the GeoTIFF into the resulting DFS2 file. Specifically, I am struggling with the following:

1. Map Projection Type
2. Origin and Orientation, including:
   • Geographical coordinates (input type, longitude, latitude, Y-axis pointing north)
   • Projected coordinates (easting, northing, grid rotation)

Although I managed to define the map projection by using an existing DFS2 file as a template, my goal is to extract all necessary information directly from the GeoTIFF file, without relying on a DFS2 template.
To support this, I’m sharing the following files for your comments and suggestions:
a) The Jupyter Notebook currently used to process the input GeoTIFF and template DFS2 (note: the template contains the map projection only as a comment)
b) The GeoTIFF files (.tif and .tfw)
c) The DFS2 template
d) The resulting DFS2 file generated by the Jupyter script

I would greatly appreciate your thoughts on how to best extract and apply the spatial metadata from the GeoTIFF to correctly configure the DFS2 file, including orientation and origin.

Looking forward to hearing from you.

Kindest regards,
Alex

Hi @elche6, have you tried using the WKT string from https://spatialreference.org/ref/epsg/26912/prettywkt.txt ?
