How do you do the map? Just put the info in the URL?
How do I do it?
I use the url
https://www.inaturalist.org/taxa/map?taxa=
I then go to the species pages and search for the species: e.g.
Fourtoe Sengi = https://www.inaturalist.org/taxa/43226-Petrodromus-tetradactylus
so I add 43226, to the url
[actually I go to the genus in the Elephantulus case, and open all the species from the listed children]
& repeat until all taxa are on
then I click on the url to activate it, zoom and pan the map until I am happy (which adds the position text "#6/-26.333/28.602" (the zoom factor plus the central latitude and longitude)) and then copy paste the url.
Which is the long way of saying what you already said. I "just put the info in the URL"
Brilliant! Thank you :-)
