Australian mining company VA Erberg tests the GS!* T at one of their operations. They're particularly interested in the safety aspect—to be able to make observations while standing back from dangerous edges—and immunity to the many magnetic hazards of the mining sites.

Full Tilt

Beyond the electronic bubble: Integrating self-calibrating, magnetically immune tilt compensation in a high-precision GNSS rover. This is not just another rover with an electronic bubble and tilt compensation. This new technology represents a genuinely significant step in the evolution of GNSS rovers. We are presenting this look at—and inside—the Leica Geosystems’ GS18 T not as...

Getting out Is a Good Thing

Field Notes Although I have been active in the surveying profession in several ways over the years, including serving as the editor of Field Notes, I really haven’t ventured out much to seek face-to-face encounters in various venues and settings, but that recently changed a bit and has produced a new perspective for me. In...

Tunnel Monitoring from Above

UAV digital monitoring delivers significant benefits as part of a major German tunneling construction project. The German city of Karlsruhe plays a decisive role in transport planning in the southwest of that country, with more than 300,000 inhabitants, 160,000 vehicles in the main part of the city, and 190 million train passengers every year. Highway...

Over Roads and Quarries

A surveyor with a construction company in Northern Ireland uses UAVs to develop highway construction and for adjoining quarry quantities. Improving infrastructure has become crucial to local and global economies due to increased strain on roads and public transport from a rising population. When GRAHAM Construction and its partner, Farrans, were jointly awarded the contract...

Law & Order

The sunlight had magically poked through the winter aspen forest in such a way as to warm through two areas in the snow, both of them survey monuments lying about four feet apart. One was a 3 and 1/4-inch aluminum cap, stamped with the surveyor’s state license number, posted with a government-issued, yellow “Forest Service...

Improving GNSS in the Urban Canyon

To prepare you for the this blog post, I wish to point out that I am a geospatial expert and can hold my own around the ins and outs of survey, so going to an event at the Ordnance Survey on “3D mapping for the improvement of GNSS in urban areas” was an eye-opener. You...
