• Abstract:
  As more bridge inspection programs incorporate unmanned aerial systems (UAS) as a tool to enhance the inspection process, fact-based information on optimum specifications for the sensors UAS can carry and other key operational considerations impacting UAS imagery will aid bridge owners and inspectors when considering the acquisition and operation of UAS. Research for this TechBrief and its companion report was conducted both in the field as well as in a laboratory setting to capture and analyze data that will assist agency decisionmakers when considering integrating UAS into their inspection programs. This TechBrief discusses the testing conducted at the University of Maine to examine the key parameters that can be controlled or managed by the operator to positively impact the quality of UAS imagery.
