ivebeen is a simple tool for extract EXIF out of images taken by smart phones(iPhone, Andorid), and converts those information to geojson.

So basically, the geojson is very handy to be rendered on Maps, like google maps.

First you need to install it:

gem install ivebeen

and then simply use the generate sub-command to generate the geojson file.

ivebeen generate "/Users/jtqiu/Dropbox/Camera\ Uploads"

and after a while, you should find a file named places.geojson in current folder.

That's it.
