I have not managed to find much by Googling. I'm happy to continue investigating if anyone is happy to provide any pointers to where I should be looking. Any advice, pointers or help would be greatly appreciated. Many Thanks Scott Smith Open Cosmos p.s. I'm not sure if this is relevant or helpful, but I have managed to have some partial success with an older version of gdal and some "single variable" files I created from the original. Included for information, the gdal version is GDAL 3.3.2, released 2021/09/01 and a file which worked with gdalinfo is https://drive.google.com/file/d/1r4R2gy0w2nyEv1fwmMNNR8CHhwjvayIk/view?usp=sharing<https://eur06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdrive.google.com%2Ffile%2Fd%2F1r4R2gy0w2nyEv1fwmMNNR8CHhwjvayIk%2Fview%3Fusp%3Dsharing&data=05%7C01%7Cjukka.rahkonen%40maanmittauslaitos.fi%7Cc25e0b0ca843423558f608da8c33a3d2%7Cc4f8a63255804a1c92371d5a571b71fa%7C0%7C0%7C637976450669208186%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=IhJTrg4lnBCIABpwpwTKiKBA3rJF0B%2FcLvIz%2BrOpqjM%3D&reserved=0> .
