The City of Rotterdam is developing a digital twin of the city. 3D vector and image data of the above- and underground infrastructure, zoning regulations and city by-laws, data streams from real-time sensors, applications and […]
Recently Greg Johnston of Sensors and Software gave a very informative webinar on the factors that limit the depth to which ground penetrating radar (GPR) is effective in detecting objects. Greg showed how statistical averaging […]
It is estimated that unreliable location information about underground infrastructure represents a $50 billion drag on the U.S. economy. Comparing the United States and Japan reveals a startling difference in the annual incidents of underground […]
Montana has recently revised its statutes governing the installation of utilities on state highway right-of-ways. The revised statutes require Administrative Rules regarding utility occupancy on state highway right-of-ways. The updated Administrative Rules mandate that as […]
Without accurate maps of underground infrastructure, every construction project has the potential to become a disaster site. Incidents of underground utility damage are more frequent than many people realize. In the U.S. there are between […]
The effects of population growth, urbanization and climate change are motivating us to contemplate serious changes in how we build and maintain buildings and infrastructure. This change will require new tools. There are important industry […]
Engineering design is typically done on a desktop computer, using CAD or BIM software. Models are viewed in 3D or 2D on a monitor. Increasingly they can be viewed in mixed reality. At a SPAR3D […]
There have been significant advances in technologies for detecting underground infrastructure including inertial locating, novel radar technologies applied to ground penetrating radar (GPR), and software for post processing GPR signals to produce tomographic images. Each […]
