Precisely Shot

Aerial imaging, GIS, and GNSS play a crucial role in the success of golf’s 2018 U.S. Open Championship. “Basically, we need to construct a small city—every year and in a different location,” said Timothy Lloyd, senior manager of U.S. Open operations at the United States Golf Association (USGA). Lloyd’s team is charged with planning and...

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...

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...

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...

Radiant Earth

Connecting the global development community to Earth imagery and primary analytical tools. Nonprofits working on global development issues have had great difficulty acquiring and using a staple source of geospatial data in the form of Earth observation imagery collected by satellites. Anne Miglarese, the founder, and CEO of Radiant.Earth is working to change this. Miglarese...
