In every industry there are two ways of getting things right. One is to rely on the individual brilliance of the people doing the work: a steely-eyed foreman, a time-served fixer with a sixth sense, a site engineer who can spot a millimetre at thirty paces. The other is to design a process that makes […]
Orthomosaics turn routine drone imagery into accurate, georeferenced maps that project teams can trust for measurement, planning, and claims. Behind every clean, CAD-ready image is a repeatable workflow that starts on the ground—before a single prop spins—and ends with deliverables your engineers can drop straight into their drawings. Between June and December 2024, 26 weekly

Ground Control Points (GCPs) remain one of the most important tools in aerial photogrammetry. Even with the rise of RTK and PPK drones that capture accurate geotags in real time, GCPs provide the reliable control that ensures an orthophoto or 3D model truly matches the ground. By surveying and marking precise points on site, we
Photogrammetry has transformed drone surveying over the past decade, and right now it’s perhaps the single most important technology driving innovation in mapping, earthworks, site progress, and as-built modelling. As photogrammetric software and hardware get smarter, easier to use, and more accessible, the way that site engineers, planners, and surveyors work is changing rapidly. Experts
