3D GNSS data and the GEOID

January 19, 2017By

As high-precision GNSS horizontal and vertical data becomes less expensive to collect, greater attention must be paid when reconciling vertical datasets. In 2013, I wrote two articles entitled “Nightmare on GIS Street: Accuracy, Datums, and Geospatial Data” and “Part 2: Nightmare on GIS Street – Accuracy, Datums, and Geospatial Data” as well as conducted some webinars on horizontal datums. Reconciling... read more

How to use structure from motion to produce 3D models

December 19, 2016By

Structure from motion (SfM) is a photogrammetric range imaging technique for estimating three-dimensional structures from two-dimensional image sequences that may be coupled with local motion signals, according to Wikipedia, which I think is reasonably accurate in this case. Simply put, one can snap a series of photographs using the camera in your smartphone, unmanned aerial vehicle (UAV) or other photographic... read more

Going beyond GPS is the new order of the day

November 17, 2016By

Times have changed, and the technology landscape is much, much different today than it was as recently as ten years ago when GPS was the driving-force technology for geospatial users and geospatial equipment, and the exclusive concern of many companies in the industry. In that era, their challenges were to design the best performing receiver in terms of accuracy, size,... read more

Utility GIS users meet at Esri GeoConx

October 20, 2016By

I spent time this week at the Esri GeoConx conference in Phoenix, Arizona. The GeoConX conference is a gathering of ~800 GIS users from gas, electric and telecom utility companies. I always enjoy listening to GIS professionals from utility companies because they are faced with the most interesting GIS and data management problems. High on the list is data integration.... read more

ION GNSS+ a playground for high precision

September 22, 2016By

Every year, some of the brightest minds and most influential people in the GNSS industry that guide the direction of global GNSS system deployments (GPS, GLONASS, Galileo and BeiDou) and design the most advanced GNSS receivers in the world, gather at the ION GNSS+ conference. I almost always attend this conference, as it provides a look into what GNSS receiver researchers, designers... read more

High-precision positioning to improve as next-gen GNSS begins

August 24, 2016By

In Geospatial Solutions’ sister publication, GPS World magazine, I’ve written quite a bit about how high-precision GNSS is going to significantly improve over the next few years. Most GNSS users have receivers capable of using GPS (31 satellites) and Glonass (about 24 satellites). That generally equates to between 13 and 20 satellites in view with a clear sky and average... read more

FAA just gave US commercial drone industry major shot in the arm

June 30, 2016By

Mark June 21, 2016, on your calendar. This will be known as the day in geospatial history that the floodgates were opened for small drones to be used for business. On that day, the Federal Aviation Administration (FAA) officially introduced new rules (so-called Part 107) that allow businesses to fly small (under 55 pounds) unmanned aerial vehicles (UAVs) in the... read more

Esri introduces high-precision GNSS mobile GIS software

May 19, 2016By

The title of this column may surprise you. Esri has never built a high-precision GNSS mobile GIS software in its 47-year history. Its ArcGIS Collector did not differentiate between low-precision GNSS data and RTK GNSS receivers — until now. read more

FAA makes progress accommodating commercial UAS operations

April 22, 2016By

The Federal Aviation Administration (FAA) took a major step forward in expanding commercial UAS/UAV operations in the U.S. airspace. It’s chief said April 19 that the FAA is preparing to take another major step forward in further opening up commercial UAS/UAV operations by eliminating the need for a 333 Exemption for operating small UAS/UAV. On March 29, the FAA announced it was doubling... read more

What really matters to GIS professionals

March 17, 2016By

Surveyors are short-term, project-based data generators. On the other hand, GIS professionals are long-term data managers. Therefore, for surveyors, their data doesn’t require accuracy, it requires precision. On the other hand, GIS professionals value accuracy much more, or at least they should. read more
