I would appreciate the ability to download all my data off of iNaturalist in the case that iNaturalist dies for one reason or another, or my account is deleted, etc. It would be a huge shame to lose both my effort in observing and posting observations and the effort of so many identifiers who have helped name them.
Currently there is the option to export all your observations into a spreadsheet, but that doesn’t include the photos. I have all my photos backed up on a hard drive, but I know of people who don’t, and reuploading them here or somewhere else from scratch would be awful. Ideally downloading them from my iNat observations would have them formatted to be compatible with the spreadsheet or something like that so that information about which photos are associated with which observation and identification is kept.
I’m not planning to leave iNat anytime soon, and I don’t see any of these unfortunate events as likely to happen any time soon, but it’s just something I think about occasionally. Google, facebook, Flickr etc. have similar features.
