What happens if my camera can't see all of the pile?
The app evaluates each measurement, displaying a 3D visualization with red on surface areas that the camera did not see. The app predicts the surface for these areas and estimates a volume. Users will improve accuracy and precision of measurements by capturing as much of the pile surface as possible.
Will SR Measure work for stockpiles in bins and bunkers?
Bins and bunkers are supported with an Enterprise subscription. SR Measure with a Professional license is limited to freestanding stockpiles.
Can the app measure trenches or pits?
No, the SR Measure app is purpose built to measure stockpile volumes.
Can SR Measure work indoors?
Yes, the app does not require precise GPS locations making it a convenient option for indoor stockpile measurement.
Is there a pile size or shape limitation?
The SR Measure app does not have restrictions on pile size or shape.
How repeatable are the measurement results?
Measurements in the app are highly repeatable because of the precision of our proprietary algorithms. For example, one of the largest contributors to variations in measurements is determining the pile toe. The SR Measure app determines the toe using a consistent process for scoring stockpile risks and attributes, ensuring consistency between measurements.

Is SR Measure a new app?
No. SR Measure was originally launched in 2013 using the name “Stockpiles”. The app was re-launched in 2021 with an improved design and a new name: SR Measure. In 2023, on-device measurements and single-user accounts were implemented.
Can I download measurement reports or share them via the cloud?
Users with an enterprise license can download measurement reports via a web portal. A professional license does not have access to sharing or downloading measurements.
Can I measure stockpiles in units other than cubic yards?
Yes, you can measure in: cubic feet, cubic yards, and cubic meters. Unit of measure is set in the Account tab.
