I’d like to develop a Ruby on Rails app, specially with a mobile web interface, It’s a really simple Google Maps powered app, where the user will go in and get directions for a given Place inside a Complex.
Can anyone point me in the right direction? Regarding tools and what tips/tricks I should keep in mind?
I also have a doubts regarding how to determine the user location from a mobile device. How is this accomplish?
You can get location information from the browser using the HTML5 geolocation API.
The best library I have found that supports this cross-browser is: http://code.google.com/p/geo-location-javascript/
The google maps v3 API is very easy to use, so just go start playing with that: http://code.google.com/apis/maps/documentation/javascript/
