Part 1: Foundations for Computing Error Ellipses

This entry is part 1 of 6 in the series April 2017Standard 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...

Should we settle on the Moon before Mars?

Back to the Moon? Or—Straight on to Mars?

This entry is part of 22 in the series PangaeaEditor’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,...

Leveraging Point Clouds

This entry is part 6 of 6 in the series April 2017Above: 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...
