Not a TIFF file

vlc27
Dear community,

I am posting this message in order to seek your help. I have searched throughout the whole forum, trying to find the answer, but none of the results was related directly to the error message I got.

So, as far as I know, there have been a couple of problems in ILWIS regarding tiff files.
I exported my topograhic map from ArcGis (.ecw format) in .TIF and then imported in Ilwis as .TIF (at least I have tried).

Each time I am trying to import the .tif file in ilwis, I get the following error 'Not a TIFF file". I tried to reexport the file for several times and even used ilwis 3.4. and 3.8.5 for that.

The file's size is 10.1 GB.

Do you have suggestions? Have you ever encountered this problem?

As per the posts, I understand that it is better to import from gdal>raster, but there is no .tif format, just geotiff and other formats different from arcmap's export possibilites.

Thank you in advance,

Regards.

Ilwis imports geotiff which is a flavor of tif.  We generally use the underlying (external)gdal library for this import and I believe it only accepts geotiff ( not 100% sure).
