Volume Calculation
Menu: Civil / Start / Surfaces / Stockpile / Volume
The Volume Calculation interface in VisionLidar’s Civil Module allows users to determine the volume between a surface and a fixed elevation or between two surfaces. This tool is essential for earthwork calculations, cut-and-fill analysis, and excavation planning.
1. Key Features of Volume Calculation
✔ Supports Multiple Volume Calculation Methods – Choose between Triangulation for precision or Grid-based for speed.
✔ Handles Breaklines and Differential Contours – Improves accuracy and visualization of surface comparisons.
✔ Supports Custom Surface Boundaries – Use polylines to define specific calculation areas.
✔ Automatically Generates Resulting Surfaces – Save and visualize the intersection of calculated surfaces.
2. Understanding Volume Calculation Methods
A. Reference Surface Selection
Existing Surface – Compare against a defined 3D surface.
Z Levels – Use a flat reference plane at a given elevation.
B. Calculation Methods
Method | Description | Accuracy | Speed |
---|---|---|---|
By Triangulation | Creates tetrahedrons by projecting each surface onto the other. Accurately accounts for breaklines and intersections. | ✅ High | ⏳ Slower |
By Grid | Generates a grid-based volume calculation using prisms between grids. Less precise but faster. | ⚠️ Lower | 🚀 Faster |
✔ Breakline Consideration – Improves precision by incorporating breaklines into the calculation.
✔ Convert Triangles to Breaklines – Ensures a more faithful representation of the original surfaces (most accurate but slowest).
3. Additional Calculation Settings
✔ Swell Factor – Adjusts the porosity expansion factor of the soil due to external influences (e.g., freezing, tilling).
✔ Draw Grids or Triangles – Visualizes grid cells or triangles used for volume computation.
✔ Save Resulting Surfaces – Generates new surfaces representing the shared portion of two compared surfaces.
✔ Make Differential Contours – Creates contour lines indicating elevation differences between the two surfaces.
✔ Delimit Volume – Allows volume calculation within a specific polygonal boundary instead of using the entire surface.
4. Best Practices for Volume Calculation
✔ Use triangulation for projects requiring high accuracy (e.g., excavation, grading).
✔ Grid-based calculations are suitable for quick estimations in large-scale projects.
✔ Enable breakline conversion for the most precise representation of existing conditions.
✔ Define boundaries with polylines to calculate volume only in specific areas.
✔ Use differential contours for visualizing terrain changes effectively.
