05Report
The report is generated from the calculation.
Sample data is synthetic. Everything is calculated in your browser; uploaded files never leave your device.
The idea
Surveyed coordinates in, a volume you can trust out.
The tool turns XYZ survey points into triangulated terrain surfaces, compares the existing ground with the excavated surface, and integrates the difference across every triangle. It also cuts section views along the excavation, so the result can be checked the way engineers are used to, and writes the quantities to an Excel report.
How the volume is calculated
- Survey points (easting, northing, elevation)
- Triangulated surfaces (TIN): existing ground and excavated surface
- One composite TIN carrying both levels at every vertex
- Volume = existing ground − excavated surface, integrated over every triangle
It is not area × average depth: where the two surfaces cross, a triangle is clipped at that line, and the depth is integrated exactly over each part.
About the demonstration
The Excavation Volume Engine above runs entirely in your browser. The three samples are generated example sites (synthetic data); you can also upload your own X,Y,Z points, which never leave your device. The numbers, sections and the Excel report are computed from the surfaces, live.
