Spot levels drop onto the terrain, contour lines drape the hills at a 2 m interval — then press Plan view and watch the 3D world flatten into the familiar contour map engineers read every day.

The survey team records ground elevation at well-distributed spot points across the site.
Software interpolates between the points and threads a contour line through every equal elevation — here at a 2 m interval.
Close contours mean steep ground; wide contours mean gentle slopes — rotate the hill and see why.
Switch to Plan view: looking straight down, the 3D terrain becomes the 2D contour map delivered with every topographical survey.
Stylized real-time simulation. Deliverables include contour plans at 0.5 m–5 m intervals, DEM/TIN surfaces, sections and earthwork volumes.
