For a new project I’m working on, I will make extensive use of Google Maps. At this moment I’m doing some research to find out what the best practices are to use Google Maps in Rails applications. I also want to find out what tools there are.
The first projects I ran into are the tools which simplify the creation of a map: Cartographer and YM4R. These two projects give the user a Ruby based approach for building maps. According to Andre Lewis in his Google Talk about Ruby and Google Maps you’ll run into the limitations of these projects very soon if you’re building complex applications. Andre is one of the writers of the new book about Google Maps and Rails, called “Beginning Google Maps Applications with Rails and Ajax: From Novice to Professional”.
B.t.w. It looks like the cartographer project is dead, so if you want to use this way of building maps, there’s only one solution left, YM4R.
