All that is required is elevation data from LiDAR or UAV photogrammetry in the form of point clouds which can then be converted into a Digital Elevation Model (DEM)/Digital Surface Model (DSM) as per this tutorial. It is a relatively simple process that can be performed with free and open source software in a few simple steps. If the stockpiles overlap, use Interpolate Z feature to draw the boundary.Calculating volumes of earth, aggregate or holes over varying terrain is a challenging mathematical task that can have a huge impact on project budgets or predicted revenue.Use the top-down 2D mode to get a better volume annotations visualization within the Viewport.For example, if you have to regularly monitor stockpiles that keep the same bases, you can import a DXF bases file. It is possible to import a DXF file to define stockpile boundaries.You can launch multiple stockpile calculations in one click by selecting multiple boundaries before clicking on the Stockpile button.Set the appropriate export format in the box and click Export Stockpiles. You can also export stockpile values as a spreadsheet (.csv) or GIS file (.shp). You can create a Stockpile PDF report by clicking on the PDF Export button. In the Export tab, there are multiple options to export the stockpile calculation results in the Stockpile group. Tick the Volume checkbox in the annotation settings found in the TOOLS for Stockpile tab to display the net volume value within the Viewport. Stockpile inventory results are available in the Volume section of the HOME tab. The stockpile calculation is done between the current terrain and the selected reference type. Launch the stockpile calculation by clicking on the Stockpile button in the Volumes group of the TOOLS for Stockpile tab. Notes! It's possible to change the material after the stockpile creation via the TOOLS for Stockpile. "Undefined" is the only available option by default. You can create and manage materials using the Material Editor. Select the material for the stockpile type from the Material dropdown menu. This feature is only available when the project contains multiple Terrain States (Peak user only). Select Terrain State and choose the reference Terrain State in the drop-down menu. Select the Flat method and set the level value in the elevation box.Ĭompare with the previous surveys and analyze stockpile differential. Select the Flat Minimum method to generate a reference surface under the stockpile at that ground level.Ĭompare the stockpile to a defined flat floor level. You won't need to take care of the vertices elevations, but you should ensure that at least one vertex is placed on the ground in front of the stockpile. Use a boundary that follows the walls to create the baseline. In that specific case, it is not possible to draw a boundary at the bottom of the stockpile. Stockpile areas are sometimes organized with walled spaces. It is essential to accurately draw the line along the bottom of the stockpile. Select 3D Surface, the base surface is triangulated on the vertices of the stockpile boundary their Z values are very important. You can choose the reference type in the Volumes group of the TOOLS for Boundary tab. Select the appropriate reference type depending on the use case. Note! Peak users can activate the Guided Breakline Tool to make the line selection easier and quicker around freestanding stockpiles. In general, the first step is to remove those objects by using Replace Terrain tool. Conveyors and machines-like wheel loaders-are often over stockpiles. It is important to remove objects that hang over the pile before launching a stockpile calculation you don't want to include them in the material volume calculation. This article describes a step-by-step guide to help you calculate your stockpile. It is also possible to automatically generate a user-friendly PDF report or export the results as. Virtual Surveyor includes tools that help surveyors generate stockpile calculations in a simple and accurate manner, from the drone data. It's now quicker, safer, and easier to collect data over large stockpiles however, it can still be difficult to use drone data to generate stockpile calculation reports. Drone surveying is a game changer in those situations. Surveyors measure stockpile volumes on construction and mining sites as well as quarries, aggregates storage sites, or landfill areas.
