I'm looking forward to it so long as it is not as lame as the M210 or M600 implementation of "RTK".

Thank you, Alexey.

I think I remember that generating a DEM with the demo version is not possible.  Is that correct or I am mistaken?

Global Mapper is only $500 and then you'll be able to do much more than Pix4D.

Global Mapper would still require an additional SFM application, correct?

Hello dpitman,

PhotoScan Pro can perform basic measurements, that include volume measurement based on the DEM - you can draw a polygonal shape in the Ortho view, right click on it, choose Measure option and switch to Volume tab. There currently you can choose between three options of the base plane: mean level, custom level and best fit.

You have used mesh-based volume calculation and that procedure is more complicated that measurements on DEM.

I was just following the tutorial.  Is there a documented workflow for the DEM approach?

Thanks for the input.  I was hoping I was missing something in Photoscan.  Pix4d can do this pretty easily but of course is 2x+ the price.

I am using the demo version of Pro in order to evaluate whether it is a good fit for processing stock piles.  I followed the tutorial which worked ok.  But it seems like a lot of steps to isolate and measure piles when there are a lot of them.

Is it true that each pile must be isolated, holes closed and then it can be measured?  Is there a better workflow when dozens of piles need measured?

Thank you.
