[gdal-dev] An issue when trying to add TIFFTAG_DATETIME to BigTIFF raster

[Андрій Марчак]

Hi,

I have an issue when trying to add TIFFTAG_DATETIME to BigTIFF raster. Here
the input metadata:
ExifTool` Version Number         : 11.79
File Name                       :
cushing_north_high_high_mosaic_7.45cm_utm14_wgs84_meters_2019-01-17.tif
Directory                       : D:/temp
File Size                       : 3.4 GB

File Permissions                : rw-rw-rw-
File Type                       : BTF
File Type Extension             : btf
MIME Type                       :  image/x-tiff-big

I run this code:
<gdal_translate
D:\temp\cushing_north_high_high_mosaic_7.45cm_utm14_wgs84_meters_2019-01-17.tif
D:\temp\cushing_north_high_high_mosaic_7.45cm_utm14_wgs84_meters_2019-01-17_Copy.tif
-mo *TIFFTAG_DATETIME="2019:01:31 09:00:00-07:00"* -co COMPRESS=LZW -co
BIGTIFF=YES>

And I got the following metadata for some reason:
ExifTool Version Number         : 11.79

Image Size                      : 28194x38514
Megapixels                      : 1085.9

I need to add a tag *"Date Time", but not "Modify Date"*. I was doing the
same for a few BigTIFF rasters, but with the same results.

Ideally, I want to add a tag *"Capture Date Time"*, but, I found, that GDAL
can deal with the following baseline TIFF tags as dataset-level metadata:
