Export OrthoMosaic with nodata_value

[sven_a]

Hi,

Maybe at the wrong location in this forum but I am now using this function to export an orthomosaic with a nodata value of -10000 in Python:
       
chunk.exportRaster(db.rgb_pg_path, nodata_value=-10000, save_alpha=True, white_background=False, source_data=Metashape.OrthomosaicData, image_compression=compression)

Sometimes when we have issues with the automatic processing we would like to export an orthomosaic with the normal user interface. However I cannot find an option to set the nodata_value there?

Kind regards,

Sven

Hello Sven,

No-data value is saved only if the output data format is Float-32bit. In this case in GUI you'll see the No-data Value field instead of the Background Color option.

You can use Raster Calculator and have output bands similar to input bands, in this case No-Data Value will appear when you switch to Index Value option in the Export Orthomosac dialog.
