I received a message from another iNat user informing me that a large proportion of my >20,000 observations are useless because they lack “Location Accuracy” data.
I mostly use an interchangeable lens camera to record images (DSLR and mirrorless cameras). I only infrequently use the camera app on my phone. Phone images are geotagged automatically. For images taken with other cameras, I have used various methods over the years to geotag them - (i) recording GPS tracks with phone or a GPS device and synching GPS locations with time stamps, (ii) a Bluetooth connection between camera and phone that allows the camera to grab GPS coordinates from the phone in real time, and, most recently, (iii) a mirrorless camera with built-in GPS capability. I then upload images through the web interface.
Regardless of what camera or phone was used and the method of GPS tagging, the “Location Accuracy” field is by default left unpopulated the vast majority of the time. On occasional phone images, I sometimes see a value in the “location accuracy” field.
I’ve been told I need to go back and add some arbitrary value to the “location accuracy” field for these observations in order to make them useful, but I’m unlikely to find the time to do that. If I did, what value would I use - some arbitrary number? Doesn’t seem very scientific. I have two questions:
Are my data really of no use without the location accuracy information?
Is there something I should be doing differently moving forward?
