Stream EM from IDS North America is a vehicle-towed radar solution for extensive 3-D mapping of underground utilities and features. To accomplish this task, it uses massive arrays of multi-polarized, multi-frequency antennas. The use of a massive array enables it to perform fast scans of large areas while maintaining a high level of accuracy. Being multi-polarized provides optimal detection of both longitudinal and transversal features without the need to perform multiple scans. It is easily dismountable, enabling it to be transported in a van. It can be reconfigured for mapping sidewalks and difficult areas. It includes a massive array of 40 antennas in two polarizations, the ability to be towed by a vehicle up to 9 mph while running continuously, accurate to as little as 2 inches with GPS or total station integration, professional subsurface survey with ability to transfer data to CAD and GIS formats, and advanced acquisition and navigation software. 303/681-8775; www.idscorporation.com.
