How to Use Custom Surface Comparison


Measuring material on uneven or stepped ground, stored in bins, stacked against benches, or in overlapping piles can require more customization than the interpolated base used by the Smart Volume

Custom Surface Comparison allows for precise adjustment of individual vertex points that make up the outline of a volume measurement. Adjusting the position and elevation of the vertices allows the measurement base to reflect the material in the stockpile accurately.

How to customize the base of a stockpile measurement 

From the measurement toolbar, select Polygon

Select from the options in the dropdown menu. In this case, select Stockpile.

Change measurement units

Select the most appropriate measurement unit for distance, area, volume, and density from the dropdown menu. This makes it easy to move between imperial and metric units as needed and create reports in your preferred units.
