Applying a Multispectral Remote Sensing Approach to Underground Electric Manhole Inspections

Woolpert and Ameren collaborated on this article for POWERGRID International, sharing a patent-pending method of providing safer and more effective utility manhole inspections.

“This collaborative, multi-industry approach increases the safety of workers and the public, efficiently maps the manhole using the latest sensor technology and GIS capabilities, and minimizes traffic impacts by reducing the time required in the field to collect data.”
