It combines palaeogeographic maps developed as a part of the PALEOMAPS venture – led by geologist and palaeogeographer Christopher Scotese – and information from GPlates, an open-source repository of geoscience information.

“I am amazed that geologists collected sufficient information to truly plot my dwelling 750 million years in the past, so I assumed you all would get pleasure from it too,” Webster wrote on Hacker Information in 2018.

“Although plate tectonic fashions return exact outcomes, you must take into account the plots approximate (clearly we are going to by no means be capable of show correctness).

You possibly can discover what the world appeared like on the time of various occasions from a drop-down menu on the correct, though based on Webster’s GitHub repository for the positioning, final up to date 5 years in the past, a few of the info could also be old-fashioned by now.

“My software program ‘geocodes’ the consumer’s location after which makes use of (Scotese’s) fashions to run their location backwards in time,” Webster instructed CNN. “I constructed the interactive globe visualisation and the geocoding and GPlates integration myself so that folks may plug in their very own areas.”
