Surveying Scientists: The USGS Does It Right

As is often the case in our tightly networked profession, one thing leads to another. In early 2017 I was contacted by the US Geological Survey (USGS) hydrologist, Brenda Densmore, from the USGS Nebraska Water Science Center. Brenda had found me through the NGS State Geodetic Coordinator web page and reached out to me for...

An Interview with Charles Kennelly – CTO Esri UK

Charles Kennelly became CTO of Esri UK in 2008, and, unlike many people in similar positions, he takes time to listen to “the little man.” I fondly remember giving a talk at FOSS4G UK a few years back and seeing Charles there front and center in the audience. After I finished he immediately told me...

Keith Belsham Branch Manager at Spatial Technologies

Spatial Technologies was started by two partners in Calgary in 2000, and we expanded first to Edmonton, then to Vancouver, BC in 2009. We are the only full-line Leica distributor in Western Canada, supporting everything from handheld Disto laser distance meters to iCON 3D machine control systems, robotic total stations, and GNSS equipment. We also...

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...
