Lumira Extension for routes on maps

Dear experts

Few weeks ago I found an interesting extension from Lumira that can draw a route given a set of GPS data points. I found that extension very interesting, but I lost the link. Now, after hours and hours searching for it again, I'm not able to find it.

Does anybody know about a Lumira extension that can draw a path/route on a map give a set of coordinates?

Appreciate your hep!
