1 January 1988 A Method For Conducting Airborne Infrared Roof Moisture Surveys
Author Affiliations +
Airborne infrared roof moisture surveys can be conducted by using the following method. Maps of the area and plans showing the location of buildings to be surveyed are studied prior to the flights. Permission for the flights is secured and local authorities are notified of the work. An infrared imaging system is mounted on the helicopter and headsets are installed to ensure that all members of the team can communicate. Color airphotos are obtained of each roof early in the afternoon. The flight crew and the spotter are each provided with maps of the installation, with numbers and highlighting used to indicate each building to be surveyed. The spotter has a clear plastic overlay on his copy that he marks to indicate buildings completed. The daytime photographic flight serves to train the team for the more difficult thermographic survey that evening. The color film is submitted to an over-night print processor just after the flight.
