Terrain intelligence

The ground, read closely.

Hachure turns survey data into terrain models you can check line by line. Built for geotechnical, forestry and infrastructure teams who sign their work.

01 Position

Most terrain tools show you a surface. We show you how it was drawn: every contour traced to a survey point, every class boundary open to inspection.

Every line has a source

Contours, slope classes and boundaries link to the survey or sensor reading behind them.

One model, any scale

From a single cut slope to a whole catchment, without rebuilding the data underneath.

Written for review

Outputs are laid out for engineers, auditors and permitting offices, not for wall screens.

02 Platform

One terrain model, read in layers.

Atlas holds the model. Slope reads it, Traverse feeds it from the field, Ledger turns it into documents a regulator can follow.

04 Method

Slow on purpose.

Survey

Ground control first. Lines, points and sensor series are logged with their error bounds.

Model

Surfaces are built from the survey and carry their revision, so any change is traceable.

III

Verify

A second reader checks classes against the ground before anything leaves the building.

Report

Findings are written with their limits, in a format the receiving office already uses.

Revisions

Every report names the revision it was drawn from.

06 Evidence

“We stopped arguing about which map was current. The model shows its sources, so the review is about slopes and not about files.”
