Aerial Imagery Meets Underground Infrastructure

Posted by Nick Bean on Mar 9, 2017 9:12:45 AM

xyHt Magazine explores how aerial imagery combined with geospatial data improves the analysis of buried infrastructure

In his article in the March 2017 issue of xyHt, Converging Worlds: Data, Imagery, and the Pipes Below, editor Nicholas Duggan discusses how Hydromax USA utilizes georeferenced high-resolution images to mitigate underground risks. Some may find it ironic that aerial imagery is used to analyze information laying beneath the ground. However, in Hydromax USA's case, truth on the ground is critical to understanding the real risk of aging water, wastewater, and natural gas conveyance systems (i.e. imagine the potential impact on buildings, homes, and people). 

Current, clear visual detail is key to Hyrdomax USA's analysis, and allows them to make better informed decisions. Duggan explained how Hydromax accomplishes this with a combination of high-resolution aerial imagery from Nearmap, data collected from field technicians, and GIS systems. "Nearmap allowed Hydromax to make more accurate decisions so that they didn’t need to send field personnel onsite to do unnecessary inspections or send them to the same location multiple times because they’d missed something. Furthermore, by using Nearmap, which maintains a large historical data archive providing temporal data, Hydromax can verify assets using time-enabled analysis, therefore finding newly built infrastructure."
