Photogrammetry: a very modern solution

Photogrammetric Surveys enable rapid data capture using specialist cameras. These are either fitted to Unmanned Aerial Vehicles (UAV) or attached to tripods and masts. Photogrammetry as a methodology is as old as modern photography. Whilst its use declined with the development of laser scanning, in recent years with the rising popularity of UAV's, and improvements in associated software, photogrammetry has ‘taken off again’.

Meet the Aerial Expert of Stonehenge

SUMO Aerial-Cam’s Adam Stanford has gained expertise over a career spanning more than 30 years. As a leading pilot within the industry, his involvement has been vital in many well-known archaeological projects across the globe. This includes Adam’s long-standing participation in the Stonehenge Riverside Projects. We took some time to ask Adam about his participation in the projects so far...

SLAM for Measured Building Surveys When Is It Appropriate?

Simultaneous Localisation and Mapping (SLAM) was first used by autonomous vehicles, to concurrently map and navigate through an unknown environment. 'SLAM' is not a particular algorithm or piece of software. Rather it refers to the problem of trying to simultaneously localise (i.e. find the position/orientation of) a sensor around its surroundings. This happens at the same time mapping the structure of that environment.

The Adventures of a Geophysicist on Holiday

SUMO’s Dr John Gater recently ventured on holiday to the Mediterranean, a short break away from Yorkshire and Real Ale. Whilst wondering around the local archaeological remains John noticed the abundance of highly visible utility services. Features that would typically require specialised survey equipment to identify, were in plain sight. In many instances, they were actually above the ground.

In a World Focused on 3D Working, Why Is There Still a Demand for 2D?

In an industry that is constantly evolving and looking towards the newest methods of working, it can come as a surprise that although there is a will to move forward there isn’t always the way. SUMO’s Tony Rogers explains why although we are seeing an increasing shift towards full 3D outputs, we are regularly asked for traditional 2D deliverables.

Are You Willing To Risk Hitting Buried Utilities?

It’s well known within the survey industry that underground mapping surveys completed at the pre-demolition stage of a project yield all-round benefits. However, in our experience many clients don’t understand the importance of the survey work being completed pre-demolition. This and can end up demolishing more than just their site, but also the quality of their survey results.
