Part 1: Foundations for Computing Error Ellipses
Standard Error Rectangle and Error Ellipse What is an error ellipse? One of the advantages of a least-squares adjustment over other methods is that a byproduct of the adjustment is not only the most probable values for the unknown coordinates but also standard deviations on these values Suppose for a moment that we are computing...
Back to the Moon? Or—Straight on to Mars?
Editor’s note: at xyHt and Pangaea we’ve been adding “geo-space-al” content into our geospatial mix, and readers have been responding positively. Surveying on Mars is a great example. When you think about it, geospatial technology and space are inextricably intertwined; from GNSS to satellite-based remote sensing, we rely on space-based technology to tackle almost every...
HyperStacking GPR
A new technology shows promise for enabling users to see deeper targets and operate in noisy conditions. By Jeffrey Feigin, PhD Editor’s Note: The field of ground-penetrating radar (GPR) is experiencing a new wave of development. For many of our readers, first impressions of legacy GPR gear included a lot of limitations and confusing images....

Leveraging Point Clouds
Above: This image illustrates the transition from point clouds to modeled deliverables. These non-BIM solids were later used for com-putational fluid dynamics analysis to ensure proper airflow throughout the room. Three ways you can derive value from point clouds past the pre-design phase. By Daniel Chapek Reality capture is a powerful way to digitize the...
