Up, Up and Away: An article by Greg Stockton about Aerial Infrared Surveys
The imagery (IR) from aerial infrared thermal surveys of facilities, complexes, campuses, military bases and cities can be used for many purposes. Systems like supply steam and condensate return lines, hot water, lines, chilled water lines, supply water mains, distribution piping, storm water drains and sewer lines can be monitored by looking at surface temperatures/patterns. In the case of district heating systems, the distribution system can be flown rapidly and inexpensively to provide thermal data for asset management planning and predictive maintenance (PdM). As a result of finding and repairing leaks in the steam system, energy usage can be reduced with all the related benefits.
