Plastic Islands No More
4Ocean uses geospatial technology to clean oceans, helping to reduce and reimagine plastic waste. The mess is big enough that it can be seen from outer space. These days, satellite imagery reveals massive islands of plastic in oceans, and the waste is so vast that various groups and inventors are trying to combat the problem...
Outstanding Geospatial Trends at INTERGEO 2019
INTERGEO, the world’s largest summit in positioning and geospatial tech, wrapped up last week in Stuttgart, Germany, proving that even after 25 years it still can be a great show. It’s the biggest geospatial event of the year where companies around the world showcase their current innovations for the industry, and the xyHt team was...
InSAR Quake “Rainbow”
This graphic, which some folks call a rippling rainbow effect, is part of the valuable post-quake analysis of the 6.4 and 7.1 magnitude earthquakes—and thousands of minor quakes—in the vicinity of Ridgecrest, California in early July 2019. This map—produced by the Advanced Rapid Imaging and Analysis (ARIA) team at NASA’s Jet Propulsion Laboratory in Pasadena,...
New GNSS Kids on the Block
Test driving a new Tersus rover: There is more to the story than a $3,000 price tag. The advent of a $3,000 high-precision GNSS rover holds a certain appeal, even more so when a test drive reveals that it holds its own with top-end rovers in many ways. But there is more to this story...
Inexpensive Does Not Mean Cheap
A revolution is happening in affordable surveying and geospatial instruments and solutions: high-precision positioning has become much more accessible and affordable for existing and emerging end-user constituencies. Many folks may have found high-precision prohibitively expensive in the past or were resigned to low-precision choices, but now there are a lot more solution developers, manufacturers, and...
Survey-grade PPP

Has real-time precise point positioning finally hit prime time for surveying applications? The answer is a qualified yes. The dream of being able to achieve survey-grade (2cm horizontal and 5cm vertical) GNSS-derived positions without post-processing, a base,...
