Many of the technologies for detecting underground utilities and other infrastructure involve shooting some type of signal, electromagnetic or acousic, into the ground and measuring the reflection off underground objects. A major challenge for these […]
Knowing where things are underground has become important enough that in a number of jurisdictions around the world including the Netherlands, Singapore, and the U.K., initiatives are underway to create national digital twins which include […]
Inertial locating is an innovative technology that is used to accurately map underground pipe networks. But to date the technology has required non-pressurized pipes. Now a PHMSA-sponsored project has demonstrated that the technology can be […]
New regulations were released January 14 by the Colorado Department of Transportation (CDoT) that mandates (1) the electronic submission of high accuracy plans showing the location of of underground infrastructure prior to commencing a construction […]
There are fundamental differences between above- and below-ground data which may limit the usefulness of underground data in digital twins. For location data about the underground there are often data quality issues, legal restrictions on […]
Uncertain knowledge about what lies under the surface is a major cause of delays and budget overruns on construction projects. It is well known that not knowing the location of utilities and other infrastructure is […]
Mixed reality applications for visualizing underground utilities in 3D have been available from many companies for years, but have not been widely used. There are signs this is changing. For example, vGIS is an augmented […]
In the last few years there have been important advances in technology for detecting underground infrastructure including capturing ground penetrating radar (GPR) scans at highway speeds, combined GPR and LiDAR scanning for simultaneous above and […]
