Some of the bird data used is available in https://www.GBIF.org (website + APIs + data dumps) but not all of it. For a visualization like this, the place to start is probably the most recent monthly data snapshot which is availa

GBIF track the use of data we provide to scientists, where they later publish papers citing that data [1]. For iNaturalist, the list of known citations is at [2]. In most cases a download of data from GBIF will include data from more than

This looks great! I hacked around with OpenMapTiles to generate vector tiles in Arctic, Antarctic and WGS84 projections (the latter with 2×1 tiles at zoom 0) [1]. The time spent waiting for PostGIS to do reprojections etc made development

There are around a million names for plants, but due to changing scientific hypotheses, limitations of science and communication centuries ago, new technologies (DNA sequencing etc) and so on, over 600,000 of those names are synonyms for
