Over 10 years ago I started shooting RAW Images and worked with others that GPS data would be useful. I wrote about this story here.
Story of Adobe & Apple High-Value Digital Image Applications, Adobe's angst developing for the iPad, and how Microsoft missed this battleMONDAY, MAY 17, 2010 AT 3:25AM
I have a iPhone 4S and it goes with me everywhere, has GPS, but 8MP jpg with then small lens is not high enough quality. Some of my friends and I want to build a product for the data center market and we need a great lens with high resolution. So, I just got my Canon S100 with 12 megapixel, GPS, great lens and a bunch of other great features.
Much better than my first RAW camera.
And, my other RAW camera a Canon 7D.
