The TruAngle turns a horizontal angle based on a reference point and is not subject to magnetic interference. –Handheld datalogger with range pole assemblyĪnother common configuration of the LTI volume solution is to use the LTI TruAngle (pictured below) which yields highly precise XYZ data. Even when the piles are misshapen, the software will calculate volumes well within 10% of my book volume.” “I have found the MapSmart software very easy to use and extremely accurate for measuring my wood chip piles. He had this to say about the LTI volume solution that he recently adopted. It allows one person to gather the necessary data quickly, safely and accurately.Ĭhris Childers is the fiber supply manager at Ponderay Newsprint in Usk, WA. Of all the methods, the Laser Technology (LTI) solution is the simplest and most cost effective way to measure volume. UAVs (unmanned aerial vehicles) are highly capable but there is restricted use and FAA paperwork to contend with. Others are expensive and weather dependent. Some are very accurate but time consuming, often with a higher risk of injury. However, there are pluses and minuses to each method. For example, high accuracy GPS, traditional survey equipment, or a Cessna 172 and aerial camera are all common. There are a number of methods available to calculate volume. The repeatability is normally acceptable but it can be difficult to achieve good accuracy if the pile has a lot of peaks and valleys.Ĭommon Stockpiles: Wood chips, coal, aggregate, logs The amount of guess work and number of measurements depends on how irregular the shape. The volume of a pile is often calculated by taking several width and height measurements and recording the results on paper. It’s understandable given that piles can be worth millions and their volume critical to plant operations. Their numbers are pretty good although the accountant is uneasy and wants something more repeatable and accurate. They can glance at a pile between sips of hot coffee and tell you the tonnage. These are folks who wear the sole off a nice pair of leather work boots in a single year. We aren’t talking about armchair quarterbacks here. It is amazing how fast certain people can estimate the volume of a stockpile.
