Sorting observations to highlight observations that represent the largest range expansions for a taxon

[pisum]

@russell_engelman

This would also encourage users to make observations in areas to “fill in” gaps in the native range of species where they probably occur but just haven’t been sampled yet.

this sounds like the base idea for a geostrategy game. for any given taxon, create the biggest polygon with observations within, say, 1000km of each other without any other observations forming a line that bisects your polygon.

…

i don’t know if the calculation that you’re talking about – distance to nearest other observation of a taxon – actually is a good measure if range expansion though. so i’m not sure how practically useful a number like that would be.
