I just found this:

Street View Partner Program
Invite the world to explore your property
If you manage a unique property, such as a park, pedestrian mall, or university campus, you can request a free visit from the Street View team. With the Street View Partner Program, we can visit your property and collect imagery using a car, trike, trolley or even snowmobile. Once the images are added to Street View, anyone can preview your property on Google Maps and you can showcase it on your website using our APIs.

And this:

Be the Next Trekker
If you’re a tourism board, non-profit, university, research organization or other third party who can gain access and help collect imagery of hard to reach places, you can apply to borrow the Trekker and help map the world.

Google Maps has a camera mounted on a pedicab to take pictures of parks, campuses, zoos and heritage sites. I don’t see why they couldn’t use it for flatter paved bike trails (but probably not hilly paths).

Street View Trike

If Google Maps got around to mapping some key trails, either with the Street View Trike or the Trekker backpack set-up, you could then create a simulated video of any segment of that trail. A third-party site allows you to do this with any Street View mapped route currently available on Google Maps. Just type in the start and stop points and it automatically fetches and plays a simulated video of all the Street View images in sequence.
I posted about that site a few months ago: http://bikearlingtonforum.com/showthread.php?5722-Animated-Street-View-of-part-of-the-15th-St-cycletrack
This is the “video” of the 15th St. cycletrack that I created on that site. It only took about 10 seconds for me to enter the info. The site does the rest of the work.

EDIT: Oops. I thought you all were asking about mapping bike trails like the MVT. If the street is already mapped in Street View, then just use the TripGeo site to create a video. It only takes seconds, plus a little extra time to edit the route if the automated site takes you around the wrong corner. Even then, it won’t take more than a minute or two in most cases. Then save or bookmark your map animation and click on Play. Easy as that.
