Topic: Unverified datasets on the Atlas.
There is a large and developing thread over on the "UK Bees, Wasps and Ants" page at present. One of the group members wondered where an apparent sudden "invasion" of records for the Hairy Footed Flower Bee Anthophora plumipes had come from, as the NBN Atlas map was suddenly covered with records. Digging into the Atlas maps, is is easy to see that the majority of these records come from a very large dataset consisting mostly of unverified records. See https://www.facebook.com/groups/1590641 … 969198999/
Within the thread are two species distribution maps, one based verified data from iREcord over the last 5 years, and one from the NBN Atlas including the large block of unverified records. Spot the difference.
