Here in SA, we have a container deposit scheme.
Homeless folk often are able to add a little revenue to their lives by collecting the 10c per can reward.
This benfits all involved, keeping areas clean, waste down and providing a limited sort of charity.
Given the low costs of digital cameras, gps, wifi and ardunio boards, is there a hidden opportunity for businesses?
For example, geocoding and address matching is an unsolved problem - we have data sets but they are not open, or can grow stale quickly.
Grabbing a photo of a location is possible from streetview, but again it is not an open data set.
Could rugged gps enabled cameras, with a 5c per photo reward, be a good solution?
Uploading and tagging against open street map, automatically?
Given a limited amount of review, this seems a feasible alternative to ocr solutions, with a real world benefit to people in need.
For the homeless involved, the fee is less than a can or bottle, time to take photo a bit more from location to location, but easier to carry.
Obviously there would be a discomfort factor for some home owners, but I would wager most folks already harvesting recycables deal with this already.
What other data could the homeless collect, given the right infrastructure?
