I believe unless there's a small population of Natterjack toads in Null Island, surveys which are completed without a location properly specified (either not input or no gps etc.) are being given coordinates 0,0.
This would put them in Null Island (a very small island with its centre at 0,0 degrees) just off the West African coast.
Haha. It's a well known population.
I just realised I posted the wrong video also - now updated.
These points were generated in ArcGIS Pro, and are not the result of a survey. If there is no location data associated with that point, then why would it show up in that particular location on the map? I agree it must be reading a null location somewhere, but I'm perplexed as to how it is then still showing the point in the correct location.
I might possibly rebuild the spatial index on your points and check the extent of the feature class. Toadally not much use with Explorer I'm sorry as don't use it. Does it behave as expected in Pro?
