Geo-positionning across the years

In order to revise my visualization paper, I have been reading about geo-positionning. I found and interesting article quite old but that I think is a good summary. It is when reading such articles and comparing to what is feasible today (remember the video on bing's maps) that we can see how technology is evolving very fast. Many expectations have been realized such as the 3D visualization, the improvement on the quality of the pixels etc.

The references sections also list some helpful websites.
