I was surprised when I first learned (in October 2020) what observations are eligible for training, and I still am. People often assume only Research Grade observations are eligible (this surfaced in a recent forum thread), but unless something has recently changed, this is not the case. An observation is eligible to be in the training set if it has an accurate location, an accurate observed date, and a photo. For details, see this thread: How can I search for observations eligible to be in the training set?
The purpose of the current thread is twofold: first, a reminder of the fact; and second, a further plea for a straightforward method to search for observations that are eligible to be in the training set. Unless I’m missing something, the Identify tool should default to this set of observations.
Comments welcome, of course.
