I would like to be able to know and have embeded the temperature of a location when a photo was made. AI could also research past time and temperature data to add this information to historic photographs that already have time and GPS location embedded. Thank you.
There are multiple historic weather APIs available (example), it should be pretty trivial to write a script to read the location and time from the EXIF data of your images, call the API, and them dump the info into a list or back into the image metadata.
Not been done (as far as I know) fully integrated into commercially available camera software. This could be as ubiquitous as location and be widely popular.
It wouldn’t be difficult to write this script as a darktable plugin, but I imagine you’d struggle to convince the maintainers to merge code to allow for searching or categorising based on a custom metadata tag.
I’m less familiar with other programs, but I don’t see any of the proprietary options implementing this.
