Creation of .tif.xml and .tif.aux.xml

I'm processing some geoTiffs for a colleague using geoserver.

  • The files I have supplied that include .tif.xml work.
    • these files include proper header info "<?xml version="1.0" encoding="UTF-8"?>"
    • these are older files and I'm not sure how they were processed;
    • but, they contain Ersi and ArcGIS tags so I assume they were generated by Arc

  • The ones that have .tif.aux.xml (and no .tif.xml) do not work
    • these are currently being generated when I load files into ArcMap 10.2.2
    • these files start with "<PAMDataset>", so no 'proper' xml header info

The original tifs are from the same supplier and didn't have any xml files supplied with them - the only difference seems to be the ones I looked at in the past have .tif.xml's and the ones I'm looking at now have .tif.aux.xml's and it seems both of these xml's have been created by ArcMap.

So is there a way I can get Arc to generate .tif.xml instead of (or as well as) the .tif.aux.xml?

Hi,

in short:

The *.aux.xml File is ArcGIS specific. ArcGIS stores information there – e.g. after calculating statistics – so this information is available later. If you go to another system, they might be of no use …

The *.xml Files are – as you detected – standard XML Files and widely adopted by many systems to store and read metadata that might or might not be in the header of the files, too

If you got TIFF-Files (and TIFF knows a lot of header-information itself), you might be fine just using them, … you can easily use GDAL to read/list what the header in the file says. See previous posts.
