Assesses the recorded biodiversity of an area around a point: how many distinct species appear, how many records support them, how recent those records are, how many separate datasets contributed, and the breakdown by kingdom. The trap this service is built around is that record density measures observers, not organisms — a city park with heavy footfall carries more records than a roadless reserve and is not thereby richer.
