Volume measurements with increasing snow depth?

Yes. This is the question. A potential customer just mailed me and asked me to send them a proposal for volumetric measurements over piles of logs and chipped logs once per month one year ahead.
In my part of the world there can be 1 - 1½ meter of snow slowly building on the ground beginning in late october and I’m thinking that an increasing snow layer over a pile slowly smoothens out the differences between the pile and the surrounding making this measurement increasingly inaccurate until becoming impossible.
Any thoughts?

Hi @KRWaara,

This sounds like a tough one. Snow in general can be pretty hard to process given its homogenous nature. That in general may make it hard to process.

The volume measurements may also be inaccurate because of the snow fall. It is going to be hard telling volume of snow from log if they partially or fully covered. Unless you are able to remove the snow on the ground directly around it and what covers it, this may be hard to do.

One thing I just thought of that might get you close. Can you sample the snow depth and use that depth to subtract from the volume reported? It might be a small hassle, but I think this is one of those things where you can’t replace boots on the ground. I run into this fairly often in flying when trying to topo vegetated or shredded sites where you still need a fairly close grade. We regularly shoot checkpoints and then bring that into Carlson to correct. We can break the model into the number of checkpoints and re-calibrate.

Thanks for the input. I gave them a proposal but ONLY for volumetrics during the spring-summer-autumn. The only technology that might solve this is radar measurement, and as far as I know there are no such gadgets to add to my drone.

I think your right, but it depends on the tolerance they need. It may not have to be 1-2cm.
