PostGIS and Rails presentation by Ryan Dlugosz (@lbwski) for Cincy.rb in May 2015. Includes a brief introduction to PostGIS and a discussion of how to integrate it into a Rails app without the use of special gems or Active Record extensions.
See included PDF of presentation and demo Rails app. A database dump has been included for easy access to some geocoded tweets.
