UAS: It’s Unstoppable and Headed Your Way

From time to time I like to stop and think about the mission of Pangaea and explain that mission to you. My task is exposing you to new, emerging geospatial technologies. But why bother? Here’s a little analogy I thought of to help explain why keeping abreast of new geospatial tech is critical. Imagine emerging...

Above: The Z-Boat 1800 on a riverine hydrographic survey using sidescan sonar. Unmanned & Unlimited Unmanned aerial systems (UAS) get the lion’s share of media coverage, which is just not fair. Hardworking unmanned marine platforms, both surface and subsurface, have a lot to offer in the hydrographic surveying and inspection space. As a big bonus...

CADS Survey used two total stations facing each other to ensure that both ends of the 1.3-mile-long jetty met in the middle; this total station provided 1-cm accuracy when measuring from caisson to caisson.

Stretching Surveyors across the Water

Surveying the Gorgon Jetty Project on Barrow Island off Western Australia involved integrating structural, mechanical, and hydrographic surveying technologies and skills.  Barrow Island is described by some as Australia’s answer to the Galapagos Islands. The 202 km2 (78 mi2) island and its surrounding ocean are home to diverse and unique fauna, including marsupials, reptiles, sea...
