Sorry, I should have explained why I do all of that.
I combine all of that data to try and come up with interesting routes to cycle - OpenStreetMap is great for detailed cycle path data, Streetview allows me to judge whether I want to cycle along a road (I prefer offroad) and Geograph is the closest you can get to an offroad Street View. And if I am going anywhere serious (well out of town) then I replace OpenStreetMap with OS maps from Bing.
