issue creating large geotiffs from virt driver

[aleks]

I'm having some trouble creating geotiffs in certain scenarios and i can't figure out if it's something different happening when it works vs when it doesn't work or if it's simply a bug in gdal.

so I have two test cases attached.. one where a large (100k x 100k pixels) geotiff creates successfully and one where a similar image with just different data does not create successfully.

I define "successfully" if the default system viewer on my platform is able to open/recognize the image. they are from a different 100km square region in the UK but otherwise should be identical so they should both work fine.

The two test cases are of 1:10000 scale raster maps. One is the NK data set which fine and one is the NL data set which will not be recognized as a valid file. Both are created from using gdal_translate on a .vrt file pointing to 100 smaller tiles. The command used to create them both is:

$ for i in NK.vrt NL.vrt; do gdal_translate -mo TIFFTAG_XRESOLUTION=254 -mo TIFFTAG_RESOLUTIONUNIT=2 -mo TIFFTAG_IMAGEDESCRIPTION='1:10000 TILE '${i/.vrt/} -mo TIFFTAG_YRESOLUTION=254 -a_srs EPSG:27700 -co NUM_THREADS=ALL_CPUS -co BIGTIFF=NO -co COMPRESS=DEFLATE -of GTiff $i ${i/.vrt/.TIFF}; fi; done

I am using BIGTIFFF=no as i found the system won't be able to read the files ever if i use YES, I also tried to use -co PROFILE=BASELINE to form a perhaps more compliant TIFF file but the system still claims the created file is damaged/unreadable format.

BTW, my entire data set (of which these two files are just a sample of good vs bad), is 57 TIFFs, and 14 of these are unreadable (and with all these, the created .TIFF files strangely always result in under 100 meg mark when bad, seems any file produced over 100 megs end up being one of the 43 working .TIFF files).

I have uploaded both the good/bad created TIFFs, as well as the .vrt used to make them, as well as the source 200 .TIFF files the .vrt references:

The attached file is ~263 megs big, md5 sum is: 5475898a5e3cf625d09f8ffb1b17ebef

My platform is Mac OS X 10.8.5 (build 12F2560) on a macbook pro (15" retina model from 2012). And the default system viewer is called 'Preview'. It is also built-into the system and can 'quick-view' images showing a thumbnail/preview, instead of opening the standalone 'Preview' app. Neither works for the second test case.

I am using GDAL as compiled by the Anaconda python distribution with the following package versions:

gdal 2.1.0

geos 3.5.0

geotiff 1.4.1

libgdal 2.1.0

libtiff 4.0.6

Here is the output of tiffutil -dump on both images:

seems there's a size limit for the built in file-attachment system, so i uploaded them to dropbox:
