Add geographic filtering level to Compare / Suggestions larger than country


When trying to compare species either through “Compare” button in Explore mode or through Suggestions tab in Identify mode there are different levels of geometric filtering. The last level is “country”. Unfortunately that is not very good as the coverage of current data is insufficient for uncommon species or less known groups. It is possible to remove the Country filter, but that brings up results for whole world, which is not reasonable in most cases.

Therefore, I would propose adding another filtering level below Country. It could be either “Continent” or some geometric radius from the current coordinates. It may be that the latter is technically difficult, but if it is not, some 1000 … 2000 km radius would likely suffice in most cases. It might even make sense to add both with the radius set at the lower value.



You should be able to enter any place, including continents:



I see. Yet writing seems an unnecessary step - just selecting one would be faster. It should also help against wrong continent IDs.

Come to think of it, in many cases it might be good if you could not go wider than continent (= clear defaults to continent) except writing World or such in the search box.

@kueda — any reason not to include the continent on Compare/Suggestions? Most helpful for observations located in smaller/less observose countries than, say, the US.



We can do that, but if you’re identifying a beetle in Belize, is it really all that helpful to compare it to all beetles in North America? This might be useful in, say, Belgium / Europe, but not really in Belize, Benin, Bhutan…



Less useful for a hyperdiverse group like beetles, but, say, looking for birds or mammals of South America when the observation falls in Guyana, Venezuela, Suriname, or snakes of Africa when looking at observations in Liberia, Sierra Leone, Guinea, etc. Flora of Europe when looking at obs in Luxembourg, turtles of Asia when looking at obs in Laos, etc.

Fair enough. Also, “observose”: wonderful.

I loved observose.

Maybe too query intensive, but what about a 500 km perimeter and include only the species within? Just a thought.
