There was a bit of discussion on one of my observations about the accuracy field. What’s the best practice for setting accuracy when the location was set automatically from the photos geotag metadata, when that was from a phone GPS?
Unfortunately my camera app and no camera app that I’ve found will embed the GPS DOP into the EXIF metadata.
I was able to record a GPS trace separately which does record the GPS DOP and I could correlate this back into the EXIF metadata into the standard GPSDOP field.
However when then using this photo as my observation, iNat didn’t try to set the accuracy from the GPSDOP. I realise that DOP is not a direct accuracy in meters, but apparently the app I was using to record it was just setting it based on the error in meters anyway.
Should I still be attempting to set an accuracy per observation derived from the GPS DOP? If iNat could derive it from the GPSDOP EXIF field that would make it much easier to provide this information?
Is there a better way to say the location is from GPS and hence has GPS level accuracy, and not bother with the exact error in meters?
The person who commented in https://www.inaturalist.org/observations/58310748 said they just ignore observations without an accuracy and suggested to just use 10m instead, but that feels wrong to just make up an average number. Maybe if I could say 10m as an average but could be anywhere from 1m to 100m depending on the factors that affect GPS accuracy that would be more helpful (essentially saying it’s GPS accuracy).
