In the early 1990s our attempts to eliminate ground control were by establishing a fixed base at the airport and a rover on the plane. Using post-processing software, we were able to add precise coordinates to each photograph.

We Are Aviators First

With UAS, surveyors are becoming aviators. As we adopt new technology, we should heed old advice. I flew my first photogrammetric mission in the early 1980s while I was completing my geodesy degree during tumultuous times at my alma mater. While the rest of the world had disco fever, students at Universidad Central de Venezuela...

This breakwater in Costa Rica was built in the 1970s and now needs serious repair, as assessed by this image taken by a UAS.

Copter Power

A UAS rotocopter pilot directs the successful imaging of a breakwater project in Costa Rica. Unmanned aircraft systems (UAS) are finding their way into geospatial applications beyond the obvious commercial topography, volumes, and inspection applications. One particular application that is poised to take advantage of the lower cost associated with UAS data acquisition is environmental...

Aerial Mapping

Above: Fusion of data from multiple sensors is becoming a common request from geospatial users.  Here, a 10cm RGB image was fused with a classified lidar point cloud that was collected at 25 ppsm. The resultant data provides users with an enhanced ability to support a wider array of applications than each dataset used discretely.  New...

From Traditional Photogrammetry to UAS

Photogrammetry has changed substantially in the past three decades. When Jeff Yates began in the business 32 years ago, he used a projection system known as a Kelsh two-bucket plotter. “That was four generations ago of photogrammetric systems hardware,” he recalls. “From there, we went to the analog stereo plotter. That was the second big...
