HOT already has some experience of drones in Haiti using volunteers. If we can grab the images from them then I'm sure they can be processed in a similar way to the way they are being done in Haiti, we just need to work out what to do with the data. The sensors I strongly suspect just use a different part of the electromagnetic frequency, infra-red / UV for example.
Crowdsourcing bit is more map the outline of the fields and give some of the programmers and GIS people something to play with. Initially if we can get 20% of the gains for 1% of the cost of a commercial system then I think its doable and we can build on that. If it works then there will be a lot of people very interested in mapping their bit of the world in OSM to get the benefits.
I just float ideas sometimes.

- Good thoughts John,
- This is well underway with much hardware and software having been developed. As with everything, it has challenges. Googling should turn up tons of info on presion agriculture and crop health.
- The cameras, drones and image processing require fairly high technical knowledge, not likely a crowd activity.
- Drones have many other uses and may be useful for reckon/mapping in the Nepal disaster. They might be useful to augment helicopter reconnaissance and as a local eye in the sky for ground teams.  I have a back pack drone with an HD camera which can do local inspections for about 20 min. per battery. Very good for inaccessible areas.
- Drones will be our friends unless misuse brings an early demise.
- Cheers . . . . .  Spring Harrison

- I created a grid as a separate data layer using JOSM and saved it to my computer. I pull it in when I need it. The grid interval is based on my preferred zoom level.
