Hi, The exact use case is for the GDAL community help desk. I was wondering how this user https://gis.stackexchange.com/questions/469512/cannot-write-geotiff-larger-than-4gb-with-gdalwarp-despite-using-bigtiff-createo could check if their TIFF is created as BigTIFF or not.

Is there a key tool that doesn't understand BigTIFF? The only one I know of is Autodesk Civil3D.

I know that overviews may be standard TIFFs while the main image is BigTIFF but maybe the information from the header would be enough. Or have I missed some existing tool? I thought that tiffinfo at least would report TIFF/BigTIFF but it doesn’t. tiffdump does: $ tiffdump byte.tif byte.tif: Magic: 0x4949 <little-endian> Version: 0x2a <ClassicTIFF> vs $ tiffdump bigtiff.tif bigtiff.tif: Magic: 0x4949 <little-endian> Version: 0x2b <BigTIFF> Even -- http://www.spatialys.com<http://www.spatialys.com/> My software is free, but my time generally not. _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org<mailto:gdal-dev@lists.osgeo.org> https://lists.osgeo.org/mailman/listinfo/gdal-dev
