Corridor LiDAR processing pipeline
We built an end-to-end corridor LiDAR processing pipeline that turns raw mobile-mapping scans into engineering-ready DTM deliveries, holding positional drift under 3 cm on bridge decks and shipping about 200 km of corridor per week with a single operator.
The situation.
State road authority, 4,100 km of sealed corridors resurveyed on a rolling two-year cycle.
ScopeEnd-to-end pipeline for linear-corridor mobile-mapping scans: RAW trajectory smoothing against a CORS network, scan-to-trajectory registration, ground/non-ground classification, breakline-enforced DTM generation, and delivery packages conforming to the authority GIS schema. Acceptance criteria were positional accuracy per 100 m segment, not per dataset.
Target throughput of ~200 km of corridor scans per week with a single operator, accuracy certificate issued per delivery batch.

What made it hard.
Registration drift of 6-11 cm appeared on bridge decks where GNSS multipath peaked: we introduced control-point constraints extracted from the previous epoch and constrained-spline trajectory blending, holding drift under 3 cm.
Classification confused sparse understorey with low vegetation in riparian segments: we added a local height variance feature and a width-of-return classifier pass, cutting manual correction area by 71%.
