Hi
When I read some raster files (in particular thermal JPEG files), a side
car file .aux.xml appears next to it.
I would like to avoid the creation of this side car file, but I want to use
any .aux.xml file if it is already there. Yes, I could imagine there is a
performance impact if I read it several times, but I am going to read the
file only once.
The config option GDAL_PAM_ENABLED seems to be completely disabling PAM
functionality:
https://gdal.org/en/stable/user/configoptions.html#persistent-auxiliary-metadata-pam-options
Reading the documentation, I would imagine that the PAM is completely
disabled, not only the creation of the side car file while reading a raster.
Is it posible to not create the .aux.xml, but use it if present?
I see that Even has just added a patch specifically for dji images.
in general, one other option might be to not give the running process
write permission on the directory (perhaps with a read-only (re)mount) ?
