Benchmarks note illustration

The instrument datasheet is a laboratory number, and your site is not a laboratory

Range accuracy quoted at one standard deviation on a calibrated target says very little about registration residuals across a real control network.

Method note illustration

Corridor captures drift, and a scale bar will not save you past sixty metres

Accumulated scale error in unbraced photogrammetric runs is predictable enough to plan around. Two control placements remove almost all of it.

Digital twins note illustration

A twin without provenance is decoration

If nobody can tell what the geometry was measured from, when, or with what, the model cannot support a maintenance decision five years later.

Wet surfaces: what actually happens to phase-shift returns

Both sensor families degrade in the rain, but the degradation curves differ enough to change which instrument you should mobilise.

Processing note illustration

Decimation that quietly destroys the feature you were measuring

Mesh reduction settings chosen for file size routinely remove the edges dimensional checks depend on. Here is what to test before batch processing.

Capturing for a re-processing you will not be around for

Conservation capture has a different success criterion: the raw data must remain usable when today's software no longer exists.
