Re: [HOT] Idle thought time drones
Hello Steve, I did check this out, it looks like Linix only for now. Will check further, looks to have great potential. The point cloud technique is quite amazing. The Swiss system can produce very good results, even without ground control points. Thanks again, Cheers . . . . . . . .

Re: [HOT] Idle thought time drones
Hi Jon, How did that work out in Haiti? Was it just for reconnaissance of damage or for georeferenced mapping? I would think that the data would be collected to suit a specific purpose. Reconnaissance, eye in the sky flying is relatively easy to do, good georeferenced imagery is a few steps up from that. Not sure how well crowd sourcing would work for that. Cheers . . . . . . . .

[HOT] Idle thought time drones
There is something mysterious called precision farming or basically flying a drone over a field then increasing crop yields based on the information obtained. Essentially mapping but mapping fertilizer deficiencies etc. It's not HOT mapping in the conventional sense but if someone could manage to open source software and create a low cost drone with sensors it could potentially generate wealth in the areas we are trying to help recover. Could one of the Universities help perhaps? The imagery could be used for OSM as well. Cheerio John ___ HOT mailing list HOT@openstreetmap.org https://lists.openstreetmap.org/listinfo/hot
