Tunnel Monitoring from Above
UAV digital monitoring delivers significant benefits as part of a major German tunneling construction project. The German city of Karlsruhe plays a decisive role in transport planning in the southwest of that country, with more than 300,000 inhabitants, 160,000 vehicles in the main part of the city, and 190 million train passengers every year. Highway...
Over Roads and Quarries
A surveyor with a construction company in Northern Ireland uses UAVs to develop highway construction and for adjoining quarry quantities. Improving infrastructure has become crucial to local and global economies due to increased strain on roads and public transport from a rising population. When GRAHAM Construction and its partner, Farrans, were jointly awarded the contract...
Law & Order
The sunlight had magically poked through the winter aspen forest in such a way as to warm through two areas in the snow, both of them survey monuments lying about four feet apart. One was a 3 and 1/4-inch aluminum cap, stamped with the surveyor’s state license number, posted with a government-issued, yellow “Forest Service...
Improving GNSS in the Urban Canyon
To prepare you for the this blog post, I wish to point out that I am a geospatial expert and can hold my own around the ins and outs of survey, so going to an event at the Ordnance Survey on “3D mapping for the improvement of GNSS in urban areas” was an eye-opener. You...
Data Collector and Tablet Mashup – TSC7
Can’t decide between a tablet and a data collector? The TSC7 is a bit of a “mashup” between the two. A new DC (data collector/controller) was announced today by Trimble: the TSC7. The big tablet-style screen on a handheld data collector is the most visible attribute of the TSC7, but of course there is a...
Assessing the Potential
UAS-based Topobathymetric Lidar Surveys Understanding stream channel and floodplain morphology is critical for a number of efforts—from hydraulic modeling and stream-restoration design to aquatic habitat assessment. These applications require description of conditions both inside the channels and in the adjacent riparian zones. Gathering these data has typically relied on individuals on the ground or in...
