Contouring
Turn raw levels, total-station exports or GPS point clouds into clean, contoured surfaces you can actually design on — interpolated, smoothed and labelled the way a drawing office expects.
Generate precise contour maps from survey data.
Generate precise contour maps from survey data. Read the land before you shape it.

Built for the real job.
Point cloud ingest
Import CSV, DXF or total-station exports of northing, easting and reduced level.
Triangulated surface
Build a TIN over the surveyed ground points — culvert inverts, benchmarks and structures are held out of the surface, not contoured.
Contour generation
Choose minor and major intervals, smoothing and index labelling.
Long & cross sections
Cut sections along any alignment you set, taken off the terrain model.
Contour a sample surface.
Change the interval and relief — the surface is re-contoured live.
Indicative sample — a simplified calculator, not the module. The module runs on your own data, and the figures and standards it applies are the ones you enter.
Four steps, start to drawing.
- 01Upload or paste your survey point data.
- 02Set coordinate system, interval and smoothing.
- 03Review the generated surface and breaklines.
- 04Export contours to DXF, PDF or the earthworks module.

BESPA Expert Systems is suitable for the preliminary design and feasibility study phase of civil infrastructure projects. Outputs are engineering aids, not certified designs: a qualified professional engineer must check and sign off any output before it is issued for construction.
Land Preparation
Compute cut and fill against a platform level — or find the level that balances them.
Estate Layout
Fit plots and internal roads to a surveyed boundary, on your own terrain model.
Geometric Road Design (Lite)
A lite alignment module for the roads and streets inside your estate layout — centrelines, grades and cross sections.
