Lately, I have been curating quite a lot of observations that had an obviously wrong location, such as plants or insects in the middle of the ocean. For example, observations supposed to be in Central America end up in the Indian Ocean, some in South Africa are off the coast of Lybia, some from New Zealand in the Northern Pacific, some from Germany near the coast of Ireland and so on… Also, you will find a lot of them around the coordinates 0,0.
A few examples:
These errors were easy to spot because they fall in the ocean, but how many went unnoticed because they are on land?
Could it be possible to add a way to automatically check that coordinates agree with the other locality data provided by users? Or to automatically send some kind of warning to the users when the coordinates seem strange, letting them confirm that they are indeed correct or change them?
