It will be 1/200th of the width of the selected area feature, or 1/200th of the height of the pile - whichever is the smallest interval. The sample spacing is determined by the width of the area feature and the height of the pile. The elevation values for each sample will be where the elevation value from where the sample point intersects with the loaded elevation model. Pile Volume(s) will calculate the volume of a pile as defined by an area feature by creating sample elevations along the perimeter of the selected area feature to form the 'base' surface. PILE VOLUMES - Calculate the Volume of Selected Piles If you have multiple area features selected, you can also calculate theĬombined cut-and-fill volume of all of the selected area features. Specify if the Base Heights in the vertex list are above ground or above sea level values. Use the option to Specify the Base Height to use at Each Vertex to manually set the heights for each vertex in the selected feature. Selecting the option to Use Heights from Terrain Surface at Boundary will measure Pile Volumes. With the Above Ground option selected for use with Use Same Base Height for All Vertices or Perform Multiple Calculations Over a Range of Base Heights options, the base height will be determined by the user-defined height above ground, relative to each vertex in the selected feature. Volume Units - Select from acre-feet, acre-inches, barrels, barrels of oil, cubic feet, cubic meters, cubic yards, or gallons.īase Height for Volume Calculations - Allows you to manually set the base height for volume calculations, areas above the base height will be the cut volume and areas below the base height will be considered fill volumes. Use the Projection dialog to edit the linear ground units. Sample Spacing - Here you can manually specify the sample spacing to be used for determining volumes, with a large area defined over a high resolution terrain model using small values can increase processing time. Volume Calculation Type - Allows you to use a line feature to define the area for the cut and fill calculation by setting up a corridor, or an area feature for use in selling up a calculation.

Additionally, the base height can specified for all vertices, or In the Volume Calculation Parameter Setupĭialog you can specify the calculation type, sample spacing, and volume Of the area feature(s) cut the terrain surface. This will generate the Volume Calculation Parameters Setup dialog (below)Īnd measure the cut and fill volume relative to how the edges / vertices Volume (Cut and Fill) under the Analysis/Measurement right-click menu. Right-click menu to access VOLUME - Measure Selected with the Digitizer tool, use the If you have one or more line or area features This option is found under the Analysis Menu. can used to measure the volume between two terrain surfaces loaded in the workspace, the boundaries for the calculation are the edges of the terrain models. This option is also on the Analysis/Measurement Digitizer right-click menu. PILE VOLUMES - Calculate the Volume of Selected Piles allows you to quickly measure the volume of selected piles, as defined by the selected area features. This option has numerous options for editing vertices, base height values, and options to further define the volumetric calculation. Volume is found in the Analysis/Measurement Digitizer right-click menu and will measure the cut and fill volume relative to how the vertices of selected feature intersect with a terrain surface. Volume (Cut and Fill), and Pile Volume volumetric calculations work by dividing the area of interest up in to small rectangular pieces, and then calculating the sum volume of the small 3D rectangles between the two terrain models (Measure Volumes Between Surfaces) or the terrain model and the cut surface (Cut and Fill or Pile Volumes). The Measure Volume Between Surfaces., VOLUME - Measure Pile volume and cut and fill calculations are frequently used for determining the costs associated with moving material to or from a specific site, but may also be used for estimating agricultural yields, and determining the impact of a landslide event by comparing before and after volumetric calculations. Of material between two terrains or surfaces. The commands to measure or calculate the volume between surfaces commands allow you to calculate the volume Calculating the Volume Between Two Surfaces Calculating the Volume Between Two Surfaces
