  1. I like these ideas – but you’re a few KG over carry on weight 🙂

    So you take a genset – what are your fuel requirements for N hours of power, where N is the time it takes to push out a rasterised map? (assuming a downsampled raster DSM/orthophoto that can be quickly pushed over a mobile phone network is the desired product)

    What is the power draw on all these bits of gear? Would the equivalent weight of batteries do the same job? Are you constrained by transport mode (helo, or 4wd?)

    Super keen to see a parallelised ODM – I’d be happy to test against another (not free) system I have access to using a neat set of 50MP imagery I have to hand.

    1. Total weight for this unit is just under the 50lbs limit, and it qualifies as carryon (just barely in both cases).

      The power draw is about 1410Wh for the processors alone. I’d budget 1600W for the whole kit and kabootle (I’m not sure what the network switch consumes, but I wouldn’t guess it’ll eat 200 watts).

      As far as power sources, lead acid batteries might be ok for powering this, though monstrously heavy. Lithium polymer would set you back a pretty penny. 3 of these batteries could run this array for an hour: https://www.maxamps.com/lipo-23000-7s-25-9v-battery-pack (if I’ve done my math right), but ouch the $2100 for just that hour.

      Gasoline generator could do the trick, e.g. https://www.amazon.com/WEN-56200i-Starting-Generator-Compliant/dp/B00SMNLF4M/ref=sr_1_9?ie=UTF8&qid=1490923747&sr=8-9&keywords=generator but that one gallon tank would last 2-3 hours before needing refilled, so a bigger tanked generator might be necessary.

      And I don’t know about transport requirements, TBQH. I would assume a 4WD would be your transport of choice for this rig, but as it is carryon size, you might be able to transport it on smaller vehicles.

      1. OK, carry on luggage is limited to 7-10kg most places I’ve been. But yes, definitely air-transportable.

        What’s the availability of big SLA batteries in your field locations? I wonder if it is more convenient to source batteries in the field. Even in Antarctica, most stations have a battery (or five) you can borrow if you play the game properly.

        However it rolls, I look forward to a follow up post of the system in action!

  2. Dear Smathermather,
    I’m a civil engineer using gis and drone.
    I just find your ODM project and I think it’s amazing. The ODM is the first opensource project of map processing.
    I’m trying to deploy DOM on my computer. Also, I have used other two online map service which is

    Above two websites are aiming at oblique photography and 3d gis online. And indeed, the accuracy and quality of models are very nice.
    I wonder whether ODM can do this now.
    Besides I’m now learning the cesiumjs, I think ODM + cesiumjs will be a more powerful project.
    Thank you for your work!
