Stockpile Measurement - Need to mark perimeter points?

Hi, I am new to all this using my 2 x Phantom 3 Pro's and would like to know if it is necessary to put reference markers on the ground at key points on the perimeter of the likely boundaries of a stockpile which will then be visible on the MME map to use as a guide to the polygon tool, or would you just eyeball it as per the example at http://support.dronesmadeeasy.com/hc/en-us/articles/206292003-Volumetrics-Tool ?
Links to any on line tutorials for beginners would be appreciated

As long as the data is taken using our Map Pilot app and the ground reference images are uploaded along with the rest of the images you should get some good accurate elevation data.

Make sure you elect to generate the web-based volume measurements checkbox at the time of upload too.

The whole idea behind that tool is that you won't have to mark anything. To get the best results, it helps if the stockpile is well defined and on an existing flat surface. We usually switch to the elevation map so we can see the extent of the stockpiles better. Then you just use the polygon tool to draw around the perimeter and measure the volume.

Let us know if you have any other specific questions. We hope to redo our videos soon.

Tudor,
Many thanks & noted; I am looking around for companies with stockpiles who will let us do some practice mapping. Whilst searching Google earth yesterday for an aerial view of one that I had identified from the roadway, I noticed that the resolution of the latter was much higher than I had noticed elsewhere locally. This site is on the edge of my local city of Milton Keynes, UK, which I didn't realise has been mapped at a much higher resolution than the surrounding areas & it made me wonder if companies could already obtain this higher resolution 3D data from Google Earth and do the volume measurements themselves such that outside agencies were not needed. I haven't yet had time to contact this company as of yet.
See 52°04'14.18" N 0°43'04.55" W on Google Earth with 3D Buildings selected. If you go to 52°10'55.42" N 0°43'29.06" W which is about 12 miles away where my current maps are located, the resolution is much less in Google Earth than the previous.
