Reservoir surveys put two demands on a capture method that photogrammetry alone cannot meet: bare-earth levels under dense embankment vegetation, and consistent capture across large water-bounded sites. This guide explains why UAV LiDAR is the tool of choice and how the workflow is built.
Any UAV survey can quote an accuracy figure. The question that separates a survey you can build from one you can't is whether that figure was measured against independent check points or simply asserted. This guide sets out the QA/QC methodology that produces a verified, RICS-referenced accuracy statement.
Drone surveys have become the default capture method for UK quarries and surface mines — faster, safer, and more accurate than traditional GNSS rovers for volumetric monitoring. This guide explains the volumetric accuracy you can expect, the regulatory context, and the typical capture cadence.
Drone photogrammetry turns hundreds of overlapping aerial photos into a 3D model of a site. This guide explains how the technique works, what accuracy you can achieve with a Ground Control Point network, when to choose photogrammetry over LiDAR, and what to put in a brief.
Traditional CCTV pipeline inspection has been the industry standard for 40 years, but drone-based inspection — both external aerial and internal collision-tolerant UAVs — is changing the cost and safety equation for many asset owners. This guide compares the two methods honestly.
PAS 128 is the British Standards Institution specification for underground utility detection. It defines four Quality Levels — QL-D, QL-C, QL-B and QL-A — that classify how a buried service was located and how confident you can be in its position.
A point cloud is a 3D set of measured XYZ points that represents a real-world object or site. This guide compares the three core capture methods — terrestrial laser scanning, UAV LiDAR, and UAV photogrammetry — and gives you a decision framework for choosing the right one.
How thermal imaging actually works: the long-wave infrared physics behind a thermogram, the weather and Delta-t conditions a valid survey needs, the difference a Category 2 thermographer makes, when a drone beats a handheld camera, and how to read the result without over-claiming it.
Every project inherits the quality — or the errors — baked into its survey data. Here is what professional accreditation actually means in the UK, and the real risks of appointing a firm that holds none of it.
The UK’s drone regulatory framework has changed significantly in 2026. A clear account of class marking, Remote ID, the shift from OSC to SORA, PDRA fee increases, and what it all means for prof
The proliferation of drones in the UK has raised a lot of questions around the legalities of where you can fly them. If you’re wondering, can you fly a drone over private property, the simple an
Road corridor surveys map and analyse long, narrow areas such as roads, railways and pipelines. These surveys help you plan, design and maintain transport and…
