On the website including the upload page and observation page, using Firefox for Mac,
and other images from the same trail camera scheme using exif metadata
yield a correct textual description of the location (Sonoma, California, USA) but show up on the map off the coast of North Korea. In other words, the metadata are being read correctly to describe where it is, but then it is being mapped in the Eastern rather than Western Hemisphere.
I was given tens of thousands of images from trail cameras in the park taken over several years. A program from http://www.colorpilot.com was used to embed exif metadata in these images prior to my acquiring them.
I dragged and dropped a few of these into the upload page, including this bear observation:
Step 3: Looking at the observation both on the upload page and at https://www.inaturalist.org/observations/65454941 I see that the location is listed correctly in the text, but is mapped in the wrong hemisphere.
Step 4: Opening the photo in Preview or Photos on my Mac, it maps in the correct location.
I searched the forum for topics describing this problem and could not find one. I hope that I am not wasting your time. Thank you.
