I can think of two reasons why you'd want to use your data instead of Yahoo's:
1. Yahoo's images are copyrighted: If we consistently used their images instead of our data, they could be considered a derivative work, and possibly subject to copyright issues. 2. A second GPS would likely follow your track: your data is likely more accurate for the end-user of the data. Dave Gervase Markham wrote: > I just did a GPS track of some roads, and uploaded it.
