How to set qgis2fds to NOT shift coordinates during FDS code generation?

[donish-getstand]

I am generating FDS code from a digital terrain map (UTM 10 N) using the :

processing.run("Export to NIST FDS:Export terrain", {
    'chid': CHID,
    'fds_path': OUTPUT_PATH,
    'extent': EXTENT,
    'pixel_size': 1,
    'origin': None,
    'dem_layer': INPUT_FILE,
    'landuse_layer': None,
    'landuse_type_filepath': '',
    'fire_layer': None,
    'wind_filepath': '',
    'tex_layer': None,
    'tex_pixel_size': 10,
    'nmesh': NUMBER_OF_MESHES,
    'cell_size': CELL_SIZE,
    'export_obst': True,
    'debug': False
})

But, qgis2fds centers the data based on the EXTENT's centroid. How do I adjust the settings so that all of the coordinates (x,y,z in UTM 10 N) are preserved when going to fds?

I've tried put (0, 0) and (500000, 0), which is the origin for UTM 10N in for the 'origin' parameter, but with no luck. The x, y, and even z coordinates experiences a shift.

Any help would be greatly appreciated!

Hi Donish, this is an interesting request. Let me take a look at it. I am very busy these days, it is going to take some time. Emanuele

Hi Emanuele,

Thanks for taking the time to look at this issue! I did play around with the parameter values for 'origin' but I couldnt figure out how to nullify any coordinate shift; it feels like there should be an easy answer, but maybe not. Any help on this matter would be greatly appreciated!
