Straight answers on measuring stockpiles with Stockpile Reports®: how accurate it is, what it costs, and how it compares to a manual survey.
Coverage confidence, high, medium or low, comes with every measurement Stockpile Reports computes from imagery: a surface score, and a toe score wherever the pile has an open base. A walking-wheel figure or a visual estimate you enter yourself carries none, because we did not compute it. On iPhone, Stockpile Reports measures within 5% of stockpile volume, and within 1.6% with digital or physical safety cones.
You can start free. The Personal plan measures one freestanding pile a day at no cost. Professional is $20 a month or $200 a year for unlimited scans on one phone. Business plans for teams start at $100 a month, and organizations with 200 or more piles get custom pricing. New paid subscriptions include a 7-day free trial, so you can measure before you commit. See full pricing.
A manual survey means a crew, wheel-and-tape or GPS walkovers, and often a wait for results. With SR Measure®, one person walks around the pile with a phone and gets volume and tonnage in minutes. It removes the safety risk of climbing piles, and because every pile is measured the same way every time, results stay consistent from person to person and site to site.
