Our interdisciplinary team consist of experts in the fields of Geophysics, Physics, GIS, Mechanical, Computer, and Civil Engineering. Additionally, we have expertise in multi-sensor system design and application for large-scale above and below ground monitoring of civil infrastructure, including design and implementation of various geophysical measurements system such as Ground Penetrating Radar and Electromagnetic Induction systems.

We develop mobile multi-sensor platforms using the latest and custom-designed sensor technology of many domains. Our expertise extends beyond sensing system design and includes the efficient handling and visualizing of large-scale data streams within a GIS framework. Another core competency of StreetScan is the development of automated algorithms for distilling pertinent information from large volumes of multi-sensor data (Knowledge Discovery in Big Data) and visualizing those results in web-based applications to allow informed decision making.
