Start work
Your terrain, your criteria, your study.
-
Load terrain, set terminals and road criteria, then run the screening search.
-
Evaluate supplied alignment
A different job. It measures a supplied alignment against terrain and reports what it finds. It generates nothing, and it cannot fall back to generating anything.
-
Reopen a study already saved on this backend.
Engineer demonstrations
Worked examples, to look at before you commit terrain of your own.
-
The frozen v1 generator's cached run: 40 candidates, one family.
-
A landform on which the same unchanged search finds three materially different corridors.
-
One worked example of the engine refusing a corridor, and the reason it gives.
-
The smallest end-to-end run, on a synthetic fixture. Flagged DEMO DATA throughout.
Both demonstrations are cached runs of the frozen v1 generator — not mine data and not Solomon data. The real-terrain demonstration runs on public-domain USGS 3DEP lidar; each demonstration names its own terrain source on its own page, read from the run. The corridors shown are HaulLens screening outputs, not as-built roads and not engineered vertical profiles. The recovery programme record shows the real-terrain run is not the only candidate corridor within the declared grade limit on that ground; see the validation page.
Validation & evidence
What has been tested, what passed, and what failed.
The register carries the cases that were held or refused as well as the ones that cleared, with the evidence each rests on.
