A robotic total station turns a two-person crew into one and lets the rod-holder drive the instrument. But it is not always the right tool. Here is how our field teams decide — by job, sight lines, prism tracking, and crew economics.
We fly drones over highways, farmland and construction sites every week. Here is how our crews choose between a photogrammetry camera and a LiDAR payload, how altitude trades against coverage, and what lands on the client's desk.
Across more than 3000 km of roads, our crews have learned that a highway lives or dies on its control corridor. Here is how we set control, stake an alignment, and measure earthworks so the design that leaves the office is the road that gets built.
RTK gives you a fixed solution in seconds, but a green 'fixed' light does not mean the point is good. Here is where the millimetres leak — multipath, PDOP, baseline length, the atmosphere — and the field habits our crews use to hold tolerance.
