UAS and ALTA Surveys
Part 3 Precision, accuracy, and completeness are the end goals of UAS post processing, but how you get there to meet ALTA standards requires extra care. In Parts One and Two of this article in the September and October 2022 issues of xyHt we looked at the time/cost/precision proposition of using UAS for elements of...
New Digital World Needs Data
Next-generation surveyors require specialized education and training to fill the role of geospatial data specialists. Many emerging geospatial applications, such as digital twins, 3D modeling, monitoring, virtual reality, and autonomous vehicles, are based on big digital datasets. Building a 3D digital world starts with accurate data that ties to a point on the ground, so...
Sky High
UAVs deliver practical and highly technical mobile mapping Collecting imagery with uncrewed aerial vehicles (UAVs) is ideal for a variety of applications including topographic mapping, forestry ground and canopy measurements, powerline corridor mapping, Digital Terrain Model (DTM) generation, high-resolution digital imagery, and orthophoto production, along with support for a variety of other mapping needs. Historically,...
Is High-Precision GNSS Coming to Your Smartphone?
We have seen over the past four decades how our traditional profession of making maps went from obscurity to mainstream to widely adopted, everyday reality. When I attended university for my geodesy degree in the early 80s everyone who had a car also had a road map in the glove compartment—from a basic road grid...

Looking Forward: Up Above and Down Below
by Jeff Thoreson TWO MAJOR ASPECTS OF THE FUTURE OF THE GEOSPATIAL INDUSTRY don’t have much to do with surveyor boots on the ground—or the ground at all. The next few years of progression in our fields will have a lot to do with what flies above and what lies beneath. Unmanned aerial vehicles—a politically...
