The Earth in Ruby and Postgres

this Topic will be presented by Olek Janiszewski

at September Meetup 2015, hosted by Tobias Pfeiffer

What's the math behind the Earth's coordinates systems? What are projections? What's the most efficient way to store, fetch and manipulate geolocation data in Ruby and Postgres?

If you'd like to incorporate geolocation into your app's models (users, places, events, etc.), this talk may be for you.
