Related to my previous question today, what is the nature of "TIFFFetchDirectory:Sanity check on directory count failed" error?
:: gdal_translate -co compress=zstd -co predictor=yes -co level=17 -co bigtiff=yes -of cog -a_nodata 0 Finlayson9488_SP7_08Aug2017_150cm.rgb-nir.vrt out\Finlayson9488_SP7_08Aug2017_150cm.rgb-nir.tif Input file size is 41114, 22580 0...10...20ERROR 1: TIFFFetchDirectory:Sanity check on directory count failed, this is probably not a valid IFD offset ERROR 1: TIFFReadDirectory:Failed to read directory at offset 16879620 ...30...40...50...60...70...80...90...100 - done. The translate run finished successfully and `gdalinfo -mm ...` reports no errors on the output file structure. Visually the image appears intact. (Is scanning for minmax the best way to test for a valid file? I've been using it that way for years but maybe it's not best practice.)
