Another Curveball: Coronavirus and Geospatial
Out of the blue, we’re facing another curveball. The current global concern (COVID-19, aka the Coronavirus) was generally not anticipated, and the situation changes daily. It was hoped that, by the time this is published, the situation would have calmed dramatically—but sadly it has taken a turn for the worse. Thus far disruptions have only...
Smart Maps Guide COVID-19 Investigations and Actions
As hundreds of millions of eyes stay glued to the rising toll and reach of the novel coronavirus disease 2019 (COVID-19), map-based dashboards have become a compelling, near real-time way to monitor the outbreak. They’ve also substantiated the message that everyone must take precautions and alter daily interactions. When the World Health Organization (WHO) declared...
Measuring Montana’s Future
An ambitious pilot project, to deliver high precision measurement as a statewide amenity, is under way in Montana. Agriculture, transportation, construction, mining, commerce, public safety, and the sciences have benefited substantially from such initiatives, nationally and globally—will Montana take the next step? The World’s Measuring Tape GPS is already a very beneficial technology, but...
SPARTN – New Open Data High Precision GNSS Format
Announced January 27th, 2020, Sapcorda Services GmbH announced a new, open data format for GNSS high accuracy positioning in mass market applications. To understand just how much of a potentially big deal this is, a little background first: We are all familiar with formats, for high precision GNSS applications, like those for applications that use...
GNSS: Triple-frequency Constellations
Triple-frequency observations for high-accuracy positioning has been studied for years. It’s proven to greatly improve RTK performance (fix rate, reliability, and precision) in challenging scenarios for dual-frequency RTK, for example with a very a long base line, very active ionospheric motion, and a severe multi-path environment. Triple-frequency observations also help shorten PPP convergency time significantly....
What Is South Surveying and Mapping Instrument Co.?
South Surveying and Mapping Instrument Co., LTD. holds a substantial share in the largest single market for such products. Until recently, it was not well known in the Americas; a sleeping giant may be awakening. Years ago, I started seeing South’s booths at trade shows like Intergeo and Conexpo, but in recent years I’ve begun...
