A World War II Loran receiver

The Return of Loran

An obsolete WWII navigation system is making a comeback In the 1980s, I used Loran-C to navigate on sailing trips off the U.S. East Coast. It had an accuracy of a few hundred feet and required interpreting blue, magenta, black, and green lines that were overprinted on nautical charts.  The system was a modernized version, launched...

Apps: GnssLogger & Google’s Play in GNSS

GnssLogger? Many surveyors are familiar with the U.S. National Geodetic Survey’s Online Positioning User Service (OPUS), a cloud-based processing service that allows them to upload a Receiver-Independent Exchange (RINEX) file and receive results in minutes. Soon, they may be able to achieve centimeter accuracy by accessing raw GNSS measurements on their Android phone. Google announced...

LightYX’s Beamer One projects laser lines from blueprints on to the con-struction site, giving crews highly accu-rate guidance and greatly facilitating communi-cation on changes to all stakeholders.

Seeing the Light: Laser Accuracy with LightXY

On a construction site, cement and concrete finishers, carpenters, framers, electricians, plumbers, flooring installers, and other trades people spend a lot of time taking measurements and interpreting blueprints before they can even start any of the specialized tasks they are trained and paid to perform. Until recently, it was not possible to project the blueprints...

Ground Control Points as a Service?

Ground control points for aerial, satellite, and UAS imaging and remote sensing projects, large and small, can be downloaded on-demand—what a service! We look at an example service, and link to an upcoming webinar of the subject. With cameras pointed at Earth from hundreds of cubesats and tens of thousands of UAVs, in addition to...

Aerial Surveys Weathering Corporate Consolidations

How Aerial Surveys, an independent aerial photogrammetry company, survived the wave of consolidations and continues to grow. Featured image: An Aerial Surveys International aircraft flies the Colorado River in Utah. Aerial Surveys International (ASI), based in Watkins, Colorado, provides aerial photogrammetry services using digital mapping cameras, film cameras, and lidar devices. It has remained independent...

Hidden Infrastructure in 3D: Visualizing with AR

A visualization platform overlays data displays on your view of a job site by fusing data, AR software, and mobile-device sensors. From Superman’s x-ray vision, to current technologies that use radio waves to sense objects through walls. The ability, fictional or actual, to “see” through obstacles has long been a source of fascination. (Above: An...
