does anyone know a gem / plugin / class with methods to do calculations
based on lat/lon coordinates? E.g. calculate the distance of 2 points on
the earth surface. I tried to implement my own stuff, which does not
quite give me exact results.
(quite a repost from a recent railsfrance ML thread, sorry for people
subscribing to both lists)
Not specifically a gem for the moment, but you may find the information
Are you trying to compute bird-flight distances, or driving distances ?
for bird-flight distances:
for driving distances it’s more complicated (and google API doesn’t
this functionaly AFAIK, although it’s available in maps.google.com
hope this helps
