gps_extractor

https://github.com/aashishsaini/gps_extractor

A command line application that recursively reads all of the images from the supplied directory of images, extracts their EXIF GPS data (longitude and latitude), and then writes the name of that image and any GPS co-ordinates it finds to a CSV file. Results are written to a file in the pwd as the scan runs. CSV files will be produced by default, use -html for HTML files instead. If the app is not installed as a gem, HTML output requires configuration.
