Dronestagr.am launches to showcase the world's best aerial drone pix - 4 views

  •  
    Demand for drones is exploding! Dupin wants to aggregate aerial imagery from around the globle at Dronestagr.am. In the near future we could experience something close to google maps, made with aerial pictures.

    Fun, but what would be the added benefit over high resolution satellite images?
  •  
    Remember that drones have top-view camera and front-view camera which gives more possibilities in terms of what you can do with collected data. With such a huge database and a little bit of 3D geometry we could get e.g. a 3D map of the world... I guess google can derive something like that already from their streetview images however obviously street view covers some relatively small part of the globe and also can not access places that UAV can.

    Here there's an example of a 3D picture of Tokyo (in high resolution). It is not made by drones, but I think it is something we can use them for. http://360gigapixels.com/tokyo-tower-panorama-photo/

Inferring individual rules from collective behavior - 2 views

  •  
    "We fit data to zonal interaction models and characterize which individual interaction forces suffice to explain observed spatial patterns." You can get the paper from the first author's website: http://people.stfx.ca/rlukeman/research.htm

    PNAS? Didnt strike me as sth very new though... We should refer to it in the roots study though: "Social organisms form striking aggregation patterns, displaying cohesion, polarization, and collective intelligence. Determining how they do so in nature is challenging; a plethora of simulation studies displaying life-like swarm behavior lack rigorous comparison with actual data because collecting field data of sufficient quality has been a bottleneck." For roots it is NO bottleneck :) Tobias was right :)

    Here they assume all relevant variables influencing behaviour are being observed. Namely, the relative positions and orientations of all ducks in the swarm. So, they make movies of the swarm's movements, process them, and them fit the models to that data. In the roots, though we can observe the complete final structure, or even obtain time-lapse movies showing how that structure came out to be, getting the measurements of all relevant soil variables (nitrogen, phosphorus, ...) throughout the soil, and over time, would be extremely difficult. So I guess a replication of the kind of work they did, but for the roots, would be hard. Nice reference though.
