AI Technical Summary

Benefits of technology

The present invention provides a device called SOTDiAL that can remotely measure soil conditions, such as in embankment slopes, without the need for expensive instrumentation or laboratory testing. The device is easy to transport and can provide 360-degrree data with unsurpassed spatial and temporal resolution. It is useful in applications such as remote sensing, electrical engineering, civil engineering, geotechnical engineering, and geo-environmental engineering. By eliminating the need for expensive instrumentation and reducing the risk for hazardous sites, the invention offers significant cost savings and safety benefits.

Problems solved by technology

Current practice requires expensive in situ instrumentation that must be installed and removed by personnel in the field.
Furthermore, data collection is sparse (point-wise) and is collected from individually-calibrated devices.
This practice is time-consuming and costly, while results have been shown to be poorly reproducible.
